ECG, which stands for Electrocardiography, is a common cardiac test prescribed to heart patients. Also referred to as EKG, the test is performed to record the electrical activity of the heart over a period of time. The process uses electrodes to detect the tiny electrical change on the skin that are arisen by the heart muscle depolarizing with each heartbeat.

Conventional 12 lead ECG process involves placing ten electrodes on the patient's limbs and chest. The 12 leads help measure the overall magnitude of the heart's electrical potential from twelve different angles, which is then recorded over a period of time (usually 10 seconds). This is how the overall magnitude and direction of the heart's electrical depolarization is detected at each

Apart from blood volume and contractile strength, the heart must sustain a regular cycle of relaxation and contraction to serve its underlying purpose. A series of complex electrophysiological events within the cardiac tissues predicate this regularity. These events are generally monitored using a device called an electrocardiogram (ECG or EKG). Many prefer EKG to ECG because it's less confusing with EEG, the abbreviated form of…show more content…
The heart principally has two cell types, such as working cells and specialized neural-like conductive cells. Working cells include the muscle or myocardium or the atria and ventricles, while the sinuatrial (SA) node, the atrioventricular (AV) node, and the Purkinje fibers are termed as specialized cells. These cells initiate and produce electrical impulses throughout the myocardium to regulate the rhythm of the cardiac cycle. Impulses are initiated by automaticity, also called a property of specialized cells. Automaticity reflects an ability to initiate electrical impulses spontaneously. Though it is independent of nerves or hormones, their actual rate of firing is influenced by autonomic nerves with increased sympathetics and decreased parasympathetics rate. Incongruity within this conduction will result in compromised cardiac
