Abstract:
Available evidence suggests that the ion channels that generate the normal action potential are also the basis for the arrhythmias that occur in disease states. Therefore, a thorough understanding of the function of the ion channels that generate the action potential is an important foundation for understanding the bases of arrhythmias and their treatment. This need is made all the more pressing by the discoveries in molecular genetics and membrane biophysics that have elucidated the fundamental mechanisms of a broad range of cardiac arrhythmias.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
