The Economy and the Impact on Students, Parents and Colleges Coursework
The Economy and the Impact on Students, Parents and Colleges - Coursework Example education and training of the countryââ¬â¢s workers. The wage rate of a particular country is affected by the education as well as training of a particular worker. It is a well known fact that a well-trained as well as educated worker is found to be more prolific and tends to earn more money in comparison to illiterate workers. It is the difference in the level of the training that has a propensity to separate the rich as well as poor nations. Most of the employers prefer staffs who tend to be efficient and productive as well as necessitate minimal management. There are various factors that need to be considered by the employer when making plan whether to pay for the employees training or not such as the enhancement of the productivity of the employees, loyalty of the employees and employees commanding a higher wage among others (Sturm, 2012). Most of the workers are found to be enhancing their earning capacity by emphasizing upon their capabilities about a particular job. The emp loyees are found to be interested in learning to operate the new technologies in order to compete for high wages. The employees are supposed to consider numerous factors when taking training. They need to consider the extra productivity that they expect to attain, the cost of training program and the trends in labor market for trained professionals. Most of the countries focus upon the creation of the education system so that they can attain skilled workers. The economy of the country is found to be flourishing with the increment in the number of the educated personnel (Sturm, 2012). Education and Its Impact upon Economy of New Jersey The impact of the recent economic downturn has been hard-hitting in New Jersey. This downturn has compelled the... This essay approves that two factors tend to determine how well a countryââ¬â¢s economy will do i.e. education and training of the countryââ¬â¢s workers. The wage rate of a particular country is affected by the education as well as training of a particular worker. It is a well known fact that a well-trained as well as educated worker is found to be more prolific and tends to earn more money in comparison to illiterate workers. It is the difference in the level of the training that has a propensity to separate the rich as well as poor nations. Most of the employers prefer staffs who tend to be efficient and productive as well as necessitate minimal management. Most of the workers are found to be enhancing their earning capacity by emphasizing upon their capabilities about a particular job. This report makes a conclusion that there is a considerable impact of education on the economy. With the increase in the number of the educated personnel in a particular economy, there is rise in the economy as well. It is the knowledge as well as the dexterity of the workers accessible in the labor market that determine the growth of the businesses as well as the economy. The economies possessing supply of skilled personnel brought up by means of school and college education and training is capable of capitalizing on this through creation of value added industries. The workers with high college degrees earn relatively high wages in comparison to the ones without college degrees. Hence, it is significant for the economy to place greater emphasis upon the training and education of the citizens.

Huckleberry Finn Term Paper Example | Topics and Well Written Essays - 2250 words
Huckleberry Finn - Term Paper Example n 19th century America in the South and the main characters are represented by low social castes and it is through their experiences and their view points that societyââ¬â¢s values and norms are challenged by the young protagonist. Twain presents Huck as a young, independent boy endowed with both strength and stamina of character. He is characterized by 19th century society as an ââ¬Å"outlawâ⬠and an ââ¬Å"outcastâ⬠(Johnson 1996, 5). Yet the reader is left with the distinct impression that this characterization of Huck is more of a condemnation of the society in which he is viewed as an outcast and an outlaw. Johnson (1996) explains that Huckââ¬â¢s outcast status is derived from societyââ¬â¢s failure. Huckââ¬â¢s childhood ââ¬Å"has scarcely been an idyllic one, nor has he lived the life of a typical carefree boyâ⬠(Johnson 1996, 5). Twain characterizes Huck as a sensitive and unselfish individual who struggles with moral choices, often questioning the hypocrisy of societal values and demonstrating his own sense of right and wrong. Huckââ¬â¢s society characterizes him as a misfit who is almost always in ââ¬Å"some kind of trouble, or out of sympathyâ⬠with those in control (Johnson 1996,5). Early on Huck is seen as an incompatible fit even with his good friend, Tom Sawyer and his gang. This characterization of Huck continues and strengthens as the plot moves along. For instance, in Huckââ¬â¢s brief encounter with the Grangerfords, he cannot understand their social values and contradicts it in helping their daughter escape with the son of a family the Grangerfords are feuding with. The biggest manifestation of Huckââ¬â¢s characterization as a misfit however, is his determination and efforts to help Jim the slave, escape the Phelps, rather than turn him into Miss Watson. In summary, Huck is characterized as ââ¬Å"continually at war with society, and with societyââ¬â¢s valuesâ⬠(Johnson 1996, 6). It is through his experience on the run with Jim, that Huck matures and is able to

Integrated Marketing Strategy Essay Example | Topics and Well Written Essays - 1500 words
Integrated Marketing Strategy - Essay Example Introduction In any form of business, the domain of marketing is regarded as quite significant and one of the prominent activities to be conducted in promoting as well as establishing the intended brand within the target market. It is important to note that for any business to promote or to convey information about its products or services to the targeted customers, the tool of marketing must be essentially put into efficient use. Contextually, it has been observed that companies communicate with the customers with the help of various tools of marketing, which comprise of advertising and other promotional activities to make them aware about what the business is offering to them. Unarguably, without proper marketing strategy, the success of business is quite likely to become highly uncertain and will probably remain unaccomplished upto a larger extent (Lamb & et. al 2008). Contextually, the primary intention of this report is to frame an integrated marketing strategy to promote Bullet Proof Vests as a newly launched product in the targeted market. Overview- Integrated Marketing Communication Integrated Marketing Communication (IMC) is conceptually explained as an unconventional domain of marketing management that involves the implementation of conveying succinct and all-inclusive information about the proposed brand across numerous and diverse marketing channels. It is defined by experts as an integrated approach of marketing, which is designed with the intention to ensure that all the communication activities in the domain of marketing management are applied in a unified form involving various other beneficial channels of communication (International University of science and Technology, 2013). For strategizing the promotional framework required in the launch of the product i.e. bullet proof vests, some of the tools of IMC including advertising, direct marketing, sales promotion, public relations, internet marketing, personal selling and publicity will be imple mented. These tools will together work towards the accomplishment of the set goals, which in this case is to promote the features of bullet proof vests to the targeted market and convince or encourage the potential buyers to purchase the same. Promotion Mix Strategy Promotion mix strategies mainly include two forms of approaches, which comprise pull strategy and push strategy, used according to the marketing intentions and product features to convey the information regarding products and/or services to the potential purchasers (Lamb & et. al 2008). Applying the push strategy approach, the product i.e. bullet proof vest will be promoted to the customers directly with the help of various tools of advertising during its initial introductory stage. It is worth mentioning in this context that application of a push strategy in the initial stage of the product launch will help it in gaining a percentage of market shares, countering the already existing competitive brands. In the subsequent phase, depending on the response from the customers towards the product, the pull strategy approach will be applied to encourage the customers to seek for the product from their end owing to its growing demand and preference in the market. Notably, as the armed forces and soldiers will be the targeted customers of the product, due attention will be provided towards quality

Business Case Study Example | Topics and Well Written Essays - 1500 words
Business - Case Study Example Owing to this reputation, Toyota has been able to enjoy several benefits including financial strength, customer loyalty and market share. According to research scholars Steinmetz (2010) and Quelch, Knoop and Johnson (2010), the rapid growth of Toyota had created stress on the manufacturing, engineering and design which may lead to the consecutive occurrences of quality issues. This had in turn demanded the company to recall the vehicles at the beginning of 2003. However, the quality related problem of Toyota gained national attention in September 2009, after the public release of a recorded complaint which was associated with a certain incident. There had been a recorded call to 911 regarding a car crash which was being driven by an off-duty California highway patrol officer. The crash had resulted in the death of the officer along with his family members. This accident was caused by uncontrolled acceleration due to the floor mat problem which sticks to the accelerator pedals. Owing to this incident, the company recalled 3.9 million vehicles in US on September 29, 2009. The matter gained attention in January and early February of 2010, when 2.3 million vehicles had to be taken off the roads due to the sticking pedals (Fan, Geddes and Flory 2011). Toyota stopped selling eight of their models in North America, had shut down their production plant and increased their intensity of recalls in China and Europe. The CEO and the president of the company had apologised for the recalls. Another recall associated with Prius Hybrid, one of their best selling vehicles, was initiated due to some banking problems. After this third recall, the total amount of recall between 2009 and 2010 totalled to eight million that included six million in US itself (Madslien 2012; BBC News 2012; Couts 2011; Mackenzie and Evans 2010). Critical evaluation of the business response using evaluation criteria Reputation: Owing to the crisis related to the uncontrolled acceleration, the responses by the business of Toyota had aroused concerns regarding the reputation of the organization. The car accident had affected the reputation of the organization to a lesser extent than the damages done by the disclosure and communications, recalls and apologies previously. The confidence of the customers was seen to exhibit a sudden fall. The customer reports survey showed that the pre-eminent reputation of the organization plunged from 30 percent to 19 percent (Dietz and Gillespie 2011). In case of Toyota, the recalls were done in the years 2004, 2005, 2007 and 2009-10 due to different problems related to brakes, engines and accelerators, which had totalled to over 8.5 million vehicles (Dietz and Gillespie 2011). This staggeringly high number was considered to be sufficient to damage the trustworthiness of the organization. A positive reputation can be said to be as good as the effort that is taken to create and sustain it. The excellence in reputation fails if immediate action for tr ust building contradicts this reputation. In this case,

Book Review How Did That Happen by Roger Connors and Tom Smith 2009 Coursework
Book Review How Did That Happen by Roger Connors and Tom Smith 2009 - Coursework Example Something we go to when we are very close to pulling all our hair out from sheer frustration. Summary In most cases, we just need a surefire way to fix our problem, something that will guide us to the step of recovery, to save us from what has gone incredibly wrong and probably made us lose more than just our money. In such situations, more than the financial losses, we are worried about the amount of time, effort and energy we had put into the project. More often than not, we stress over our projects and spend sleepless nights wondering if our plan will be accepted by our targets and if we would achieve the success we had set out to. And when our project fails even a little bit, we can all but hang our heads in shame and disappointment. In How did that happen Roger Connors and Tom Smith address such situations. In the scene of the global economic crisis and where it was born, all managers have at some point or the other asked how all their plans went awry and how everything they had done was washed down the drain. But itââ¬â¢s not often that one can get answers to such questions. For one, the answer to every how did that happen is completely different. And another, no one will take the onus to explain to you what went wrong when you executed a particular plan. It is almost always up to you, the designer of the plan, to figure out what went wrong in your master plan, and where. In this day and age, we have the option to outsource our problems to consultants. They do an in-depth study of our plans and arrive at what went wrong and give us suggestions on how to rectify it. ââ¬Å"Successfully holding others accountable to deliver on expectations, and doing it in a way that make others feel good about it, requires real effort and skill.â⬠(Connors & Smith, 2009, pg.15-16). In spite of this, organizations may find it quite embarrassing to hand over their failures to random strangers. It makes the most sense to find the loopholes in the plan we have worked s o hard on. Review They say prevention is better than cure. But when the disease strikes, we cannot sob over not having taken the prevention. It is time for action. However, in most cases, when such crises strike, we have no clue where to begin to clean up the mess. We know that we have to do something to save our company from drowning, to keep ourselves afloat, but when disaster strikes, we lose our cool in all the panic. We need guidance, someone to tell us exactly what to do, when to do and how to do it. The only problem is, no one ever wants to take the responsibility to be that someone, probably out of fear of flopping out again. This is when smart people decided to write about foreseen crises when they were in a sober state of mind, so that when the problem showed its ugly face, people would have somewhere to turn to - a guide, a direction to move in to rectify what has gone horribly wrong. In How did that happen, Connors and Smith have defined in a very simple and comprehensib le manner what one must do in case of such outbreaks. Rather than giving us vague illustrations and long, complex instructions that no one will understand and confusing us even more, they have managed to break down the whole concept and give us step-by-step instructions that are definite, as opposed to the ambiguity one usually finds in such books. This may be the most important factor of this book, that even in spite of being a self-help book, it actually

Inflation & The rise of cost Essay Example for Free
Inflation The rise of cost Essay Inflation can be defined as the rise of cost of goods and services in a country; and therefore the cost of living. Inflation can be measured when the cost of a product/service increases over a period of time and therefore decreases the value of money in an economy. Inflation is bad for the economy because of many reasons. One of the reasons is because inflation can decrease the value of money over time and therefore decrease the purchasing power for common people. Apart from that, it tends to create a lot of uncertainty in the economy for producers and buyers. When there is uncertainty in the economy, this leads to a lower level of investment as people are not confident enough to invest, and as a result this leads to a lower economic growth. Inflation also tends to discourage entrepreneurs to expand their businesses or to start a new business because of the high cost of goods and services. This therefore reduces competitiveness in the market which also affects international trades. When there are fewer businesses expanding or opening up, employment rate reduces which increases the level of unemployment rate. When unemployment rates are high, the crime rates increases as people find ways to survive and this affects the safety of the society. On the other hand, a lot of resources are wasted during inflation. For example, during the inflation period, people tend to save their money and spend less; therefore companies have a lower demand rate and have a high wastage on raw materials that were purchased earlier. High inflation rates also make the economy unsustainable as itââ¬â¢s not strong. Source from the US Inflation Calculator, 2009. The graph above shows the inflation rates from the year 2000-2009 in the US. As shown, there was a 3. 8% inflation rate in the year 2008, and has gone down to 0. 2% in 2009.

The Importance Of A Electrocardiogram
The Importance Of A Electrocardiogram An electrocardiogram is an important part of the initial evaluation of a patient who is suspected to have a heart related problem. There are 12 small sticky electrodes that applied to the patients chest, arms and legs. However, with some systems, the electrodes may be applied to the chest, shoulders and the sides of the lower chest, or hips. The wires are used to connect the patient to the electrocardiogram machine. The patient will be asked to remain very still while a nurse or technician records the EKG. The electrical activity created by the patients heart is processed by the EKG machine and then printed on a special graph paper. This is then interpreted by your physician. It takes a few minutes to apply the EKG electrodes, and one minute to make the actual recording. The EKG is extremely safe and there is no risk involved. In rare cases, some people may develop skin irritation from the electrode adhesive, but no serious allergic reactions have been reported. The EKG can provide i mportant information about the patients heart rhythm, a previous heart attack, increased thickness of heart muscle, and signs of decreased oxygen delivery to the heart, and problems with conduction of the electrical current from one portion of the heart to another. What Is EKG? The basic importance of electrocardiogram are diagnosing irregularities in the heart, record changes in the heart, and establish baseline for other EKG by using the electrocardiogram machine. An electrocardiogram (ECG or EKG) is a quick, painless test that records the electrical activity of the heart. It may be taken at rest or during exercise. It is the standard clinical tool for diagnosing arrhythmias (abnormal rhythms) and to check if your heart is getting enough blood or if areas of your heart are abnormally thick. Small patches called electrodes are placed on different parts of the body. Different tracings of the hearts electrical activity can be made and permanently recorded on paper or in a computer. Three major waves of electric signals appear on the ECG. Each one shows a different part of the heartbeat. The P wave records the electrical activity of the atria. The QRS wave records the electrical activity of the ventricles, and the T wave records the hearts return to the resti ng state. Doctors study the shape and size of the waves, the time between waves and the rate and regularity of beating. Importance of Electrocardiogram There are many importance of EKG but these are the main importance, diagnose irregularities in the heart, record changes in the heart, and establish baseline for other electrocardiogram. Diagnose irregularities in the heart means to provide what need to be done in the heart. It is important to know because there are different types of importance that need to be done in order to know the right heart record during the electrocardiogram testing. Some patient base on their history because a lot of their familys having failure heart problem too. This means that they need more exercise and eat more good meals. Arrhythmias may be seen on 12- leads ECGs strips of one more leads. This means that everything is required for the EKG test. It also improves the patient development because the doctor may tell the patient what is right or wrong. Condition Determined by EKG The condition determined by electrocardiogram are previous heart attack, Heart blocked, Enlarged heart muscle, Rhythm disturbances. It takes a few minutes to apply the EKG electrodes, and one minute to make the actual recording. The EKG is extremely safe and there is no risk involved. In rare cases, some people may develop skin irritation from the electrode adhesive, but no serious allergic reactions have been reported. The EKG can provide important information about the patients heart rhythm, a previous heart attack, increased thickness of heart muscle, and signs of decreased oxygen delivery to the heart, and problems with conduction of the electrical current from one portion of the heart to another. Most of the Electrocardiogram physician and basically the one who help other people that has complaining about slow heart beat, fast heart beat, irregular heart beat or any symptom that they may encountered whatever they doing. It is very important to see the physician right away for ch eck up before the heart beat will become severe problem and this will cause them to death. Junctional Tachycardia Junctional Tachycardia is believed to be caused by enhanced automaticity and is commonly the result of digitalis toxicity (Shade Wesley, 2005). Another cause includes myocardial ischemia or infraction. It can also occur at the any age without a patient history of underlying heart disease. The patient will also complain to palpitations, nervousness, anxiety, vertigo, and syncope frequently accompany with dysrhythmia. When the patient get junctional tachycardia they may also sustained with rapid ventricular rates and retrograde depolarization in their atria because the ventricular filling is not as complete during diastole, leading to compromised cardiac output and the patient may occur heart disease. The rate of the person who has junctional tachycardia is 100 to v180v beats per minute and de P waves inverted may immediately precede, occur during the absent or follow the QRS complex (Shade Wesley, 2005). Myocardial Infraction Myocardial infarction is the death of injured myocardial cells. This may occur when the person has a sudden decrease or total cessation of blood flow through the coronary artery. It is also commonly occurs when the intimacy of a coronary artery ruptures, exposing the atherosclerotic plaque to the blood within the artery. The area of the heart normally supplied by the blocked artery goes through a characteristic sequence of events describe as zones of ischemia, injury and infraction. There are also three key EKG indicators of myocardial ischemia, injury, and infarction; they are changes in the T wave, changes in the ST segment, and Enlarged Q waves or appearance of new Q waves. This means that means that anyone of this changes maybe present without anyone of the others. Placing leads on the client and setting machine control This are the steps they physician need to do before hooking up the EKG leads and electrodes to the patient. First wash hands, assemble the equipment like the EKG machine with electrodes, electrodes pad, alcohol wipes or skin cleansing agent, bath and blanket or sheet, and the patient grown. The physicians need also to identify the patient to make sure they have the right patient. Explain what you are doing, and reassure patient that this procedure is painless but the electrodes are sticky and its little bit cold and the patient need to avoid applying lotion before the test. Position the patient on bed or treatment table in a supine position with are relaxed beside their body. Covers the patient with a blanket leaving the arms and legs exposed to provide privacy. Wipe the skin with a cleansing agent to remove oils, scaly skin, or perspiration and the physician are now ready to apply the 12 electrodes. The patient needs to arrive 15 minutes before the test. There is no pain during the test and the result of the test will send it to your doctor and they will share the result with the patient in 2 weeks. There are 12 leads that will be place in the the body which is the arm, legs, and chest. What is Pacemaker? An electronic pacemaker is a small device use to control the heart rhythm. The Pacemaker electrical device use to prompt the pulses of the irregular heartbeat to a normal heartbeat. Pacemaker is people who have bradycardia. Cardiac pacing is a recognized and widely used treatment for patients presenting with bradycardia. Physicians expect patients to return to normal activities almost immediately post implantation. However, patients themselves may perceive interference to pacemaker function by various routine activities and devices, and hence continue to lead restricted, disabled lives. The aim of this study is to determine if routine activities are perceived by pacemaker patients to interfere with their device function (Pacemaker, 2008). This means that most of the patient who needs to have pacemaker is the old people because they starting to have a slow heartbeat and they need the pacemaker in order to help them breathing. The Pacemaker contains two parts the generator and the part s. The generator is tiny, hermetically sealed computer (Fogoros, 2003). This generator is roughly the size of a 50-cent piece, and approximately three times as thick. The battery life of most pacemaker generators today is 5 to 8 years. EKG interpretation Electrocardiograms are diagnosing irregularities in the heart record changes in the heart. The patient needs to arrive 15 minutes before the EKG test. Avoid using lotion around the chest, arms, and legs because the electrodes pads are sticky. For the women they may have to use gown in the hospital to avoid privacy and for the men if they have hairy hair in their chest the physicians may have to shaved if so that the 12 electrodes can hook up good. There are 12 electrodes that need to be connected during the EKG test (Electrocardiogram, 2005). The physician needs to know if the patient has a normal heart beat or irregular heart that why its very important to go see the doctor right away when people have problems about the heart. It is very important because most of the people who having symptoms are just taking any kind types of medication. When the patient taking the wrong medication without the doctor prescription the body will affect and the body will become perilous. Horizontal li nes measure time (1mm square- 0.04 secs), the vertical lines measure voltage (1mm square- 0.01 mV), and the tic mark will identify 6 sec strip intervals. Heart rate computation has the identify rate which measure ventricular rate unless otherwise specified and its also measure the R-wave. They choose to method to determine or make sure that the rate has six second method box and box method. The six second method count the number of QRS complexes occurring within 6 seconds and multiply the number by 10. During the Holter monitoring or electrocardiogram testing make sure that the V3 leads is under the right nipple if the patient is under 15 years old and if its older than 15 they can hook it up like adult. During the hook up of the Holter monitoring the first step they need to do is to take out the battery compartment and place AA battery, then insert the flashcard with the lip facing downward. Second, push the enter key twice, they will hear the beep sound, then you will be able to e nter the social security of the patient by scrolling the up down side to side keys then select ok button. Third, scroll across the top check the channels 1-3 to make sure all the hook ups are all working and good. Fourth, they should also check the first time by scrolling across the date and time. Fifth, check the duration of the scan and pacer detector by going to the settings then go to start and press the enter button. Lastly, issue the patient what they need to do after 24 hours. The physician needs to hand his/her a log sheet for their activities and symptoms. Electrocardiogram Rhythm Sinus Rhythm is a regular normal rhythm of the heart set by the natural pacemaker of the heart called the sinoatrial node or sinus node. It is located in the right atrium and refers to the normal increase in heart rate that occurs during inspiration when they breathe. Its also a small, slow variation of the R-R interval variation of the normal sinus heart rate respiration (Medical, n.d.). There is also sinus tachycardia which means the sinus rhythm is 100 beats per minute. The QT interval decreases as the rate increases. The maximum rate in sinus rhythm is usually 220-age (Medical, n.d.). The sinus bradycardia or slow heart beat is 60 beats per minute and this may due to parasympathetic dominance at rest (Cardiac, n.d.). The premature ventricular complexes are observed in 60 percent of healthy adults in monitoring. This means that the patient can take home the Holter monitoring and they have a log sheet and they have to write the time and what are they doing. The sheet also is very i mportant because it will record all the information that the physicians need it. The Holter monitor is the recording the heart beat the every time the patient realize of feel that they having a funny heart beat they may need to press the middle button of the Holter monitor. Atrial fibrillation is when human has two upper chambers and the two low chambers. The upper chambers are called the left atrium and the right atriums are the plural of atrium in the atria. When the two lower chambers contact at the excessively high rate, and its an irregular way, the patient has atrial fibrillation. (What, n.d.) Atrial flutter is when a patient complaining about their heartbeat. Most of the patient that has atrial flutter heartbeat has stop beating, and they cant realize any feeling. There are also times that when the patient is lying down they may experience fast heart beat. Most old people have experiencing this because of their age. They may need to stop drinking coffee, soda, lemonade or any drinks that has acid because this will may affect their heart beats. For the patient that has atrial flutter they have to go to emergency room right away and make sure the doctors take x-rays of the patients heart and lungs. To prevent this people need to exercise and eat healthy food. Ventricular Tachycardia is very rapid tachycardia. The causes are cardiomyopathy and heart failure can occur without heart disease. Ventricular Fibrillation: Right and Left Main Coronary Artery The right main coronary artery originates from the side of the aorta and passes along the antrioventricular sulcus between the right atrium and the ventricle. They divided into two branches, the marginal artery and the posterior interventricular artery. The portion of the myocardium supplied by the right coronary artery includes the right atrium, right ventricle, inferior and posterior wall of the left ventricle and the one third posterior of the intarventricular septum. The right coronary artery supplies blood to the SA node in about 60 percent of the population and to the AV node about 90 percent of the population. Also the posterior-inferior fascicle of the left bundle branch. The left coronary artery originates from the left side of the aorta. It divides into the anterior descending and circumflex branches. The anterior descending artery perfuses the anterior surface and part of the lateral surface of the left ventricle and the anterior two thirds of the intraventricular septum. The branches of the anterior descending artery, the diagonal artery and the septal perforators, help supply blood to the lateral walls of the left ventricle. The circumflex artery supplies the left atrium, anteriolateral, poster lateral, and the posterior wall of the left ventricle. The heart needs its own blood supply because the demand for oxygen in the myocardial cells is extremely high. The coronary arteries provide a continuous supply of oxygen and nutrients to the myocardial cell. The heart works constantly to pump blood to the body, so the oxygen consumption of the heart is greater than that of single organs. The terminal branches of the arteries have many interconnections, forming an extensive vascular network. Reciprocal Changes The reciprocal changes are the mirror image that occurs when you have two leads viewing the same myocardial infarction from opposite angles. The infracted zone is electrically neutral, so the lead directly over the heart registers only an unopposed vector moving away from it. This cause the waveform to be negative. The T wave is flipped because of depolarization abnormalities generated by the areas ischemia and injury. The concept is important to relate while looking at the EKG traces because it shows the different areas of the heart. Reciprocal change was noted in all patients with inferior infarction. This means that the ST segment depression is higher. If the Electrocardiogram traces are change the heart will detect the symptom right away or the ST segment will change. Anatomy and Physiology of EKG The heart is a hollow muscular organ that lies in the middle of the thoracic cavity behind the sternum, between the lungs and just above the diaphragm (Pre-reading). The blood enters to the heart for the major veins of the body. The superior vena cava feed the right atrium and the left atrium. The left ventricle supply the left atrium and the right ventricle are in the middle to return blood in the middle. The heart beat consist of two contractions, when the atriums contract the blood is squeezed simultaneously from the right atrium through the tricuspid valve and when the ventricles contract the blood squeeze from the right ventricle through the pulmonary valve and to the lungs. There are also two major veins that deliver blood all over the areas of the body especially in the right atrium. They called this superior vena cava and anterior vena cava. They divides directly in the heart and have different construction. Different Waves P-waves moves in a compression motion similar to the motion of a slinky, while the S waves move in a shear motion perpendicular to the direction of the wave that is travelling. P-wave is basically electrical signature of the current that cause atrial contraction. It is also the portion of the electrocardiogram tracing that represent the depolarization of the myocardium. Its depolarized in the left atrium and reflects to the right depolarization. QRS complex is the portion of the EKG tracing that represents depolarization in the myocardium and the ventricle are activated simultaneously. T-wave is deflection of the normal electrocardiogram following QRs complex and it represent repolarization or recovery of the ventricle. Sinus Arrest A rhythm can also appear irregular when a SA node fails to initiate an impulse. This can be called sinus arrest and is seen as the pause in the electrocardiogram rhythm. They rhythm leading up to the pause looks normal. Sometimes there is also suddenly absence of the P wave as well as the QRS complex and T wave. These are one whos creating gap or pause of the heartbeat. If a SA node fails to fire, then the escape pacemaker from the atria call AV injunction will initiates and impulses. Irregularity may also cause by premature ventricular heartbeat during the electrocardiogram test and the rhythm making R-R interval pause. The rhythm leading up to the pause looks normal if the EKG test is no irregular. A slightly rhythm is where the P-P intervals and R-R intervals vary. The changes of the pacemaker from site to site can lead to this type of irregularities. A cause of the slightly irregular rhythm is when initiation of the heartbeat changes from site to site of each beat. Each of the he art beat is initiates to other area. The QRS ventricle depolarize and it will become larger muscle mass. The ST segment is normally isoelectric and gently blends into upslope of T wave. The point where the ST segment is located will takes off from the QRS ventricle and it goes to the J point.
