<article><h2>Introduction</h2>ECG, also known as electrocardiography, is an electrical recording of the heart which is written down and converted into a graphical representation. Over time, it has become an indispensable tool in the diagnosis and evaluation of heart conditions. The use of ECG has become especially important in recent years due to the increasing prevalence of coronary artery disease, heart failure, and other cardiac problems in the general population. In this article, we will discuss the application field and working principle of ECG.<h2>Application Field</h2>The application field of ECG is wide and covers numerous different medical conditions. One of the most common uses of ECG is in the diagnosis and evaluation of cardiac arrhythmias. These are abnormal heart rhythms which are detected using the ECG. Other common applications include the diagnosis and management of unstable angina, myocardial infarction, and heart failure. ECG can also be used to provide an indication of the electrical activity of the ventricles and atria, which can help in the diagnosis and management of specific cardiomyopathies.In addition to its clinical applications, ECG is also used in sports medicine. An athlete\'s ECG recording can provide vital information on their fitness and performance level. It can be used to assess an athlete\'s cardiac reserves, as well as their suitability for competitive sports.<h2>Working Principle</h2>The ECG is based on a simple concept. When the heart beats, it generates electrical signals which are transmitted throughout the body. These signals are picked up by electrodes which are placed on the individual\'s body and transmitted to a device, usually a computer, which records and displays the signal.The electrodes pick up signals from different parts of the heart. There are 12 leads in the ECG, each of which is transmitted through different parts of the heart. Each lead measures a different aspect of the heart\'s electrical activity. When all 12 leads are combined, a graphical representation of the heart\'s electrical activity is created. This is known as an electrocardiogram or ECG.<h2>Conclusion</h2>In conclusion, ECG is a valuable tool in the diagnosis and management of cardiac conditions. It is based on the concept that the electrical signals generated by the heart can be picked up by electrodes placed on an individual\'s body. These signals are then transmitted to a device which records and displays the signal. ECG provides a detailed graphical representation of the heart\'s electrical activity and is used in a wide range of clinical and sports medicine applications.</article>
