ECG also known as Electrocardiography is a process of diagnosing and recording the electrical activity of the heart over a span of time. It actually senses any sudden variations of the electrical signal sent out by the heart. This method is used to detect a problem in the heart from over the skin.

Electrocardiography is the process of producing an electrocardiogram (ECG or EKG[a]). It is a graph of voltage versus time of the electrical activity of the heart[4] using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle (heartbeat). Changes in the normal ECG pattern occur in numerous cardiac abnormalities, including cardiac rhythm disturbances (such as atrial fibrillation and ventricular tachycardia), inadequate coronary artery blood flow (such as myocardial ischemia and myocardial infarction), and electrolyte disturbances (such as hypokalemia and hyperkalemia
