The heart is a muscular organ responsible for circulating blood through the body’s circulatory system. The pumping action of the heart is coordinated by electrical activity that propagates through the heart’s four chambers. This same electrical activity makes it possible to noninvasively evaluate some aspects of heart function from recordings known as the electrocardiogram (ECG). The ECG is currently the fundamental technology used by physicians to evaluate the electrical activity of the heart and diagnose conditions such as abnormal rhythms (arrhythmias), abnormal conduction, damage due to heart attacks, and abnormal chamber sizes.
