Depolarization (heart muscle contraction caused by electrical stimulation) occurs nearly simultaneously in the right and left ventricles 1-2 tenths of a second after atrial depolarization. The entire sequence of depolarization, from beginning to end (for one heart beat), takes 2-3 tenths of a second.

As the heart undergoes depolarization and repolarization, the electrical currents that are generated spread not only within the heart, but also throughout the body. This electrical activity generated by the heart can be measured by an array of electrodes placed on the body surface.

The sodium-calcium exchanger (NCX) was considered to play an important role in arrhythmogenesis under certain conditions such as heart failure or calcium overload.

A schematic frontal section through the human's heart is presented in the following figure. The heart pumps the blood by repeated contractions of its muscles. These cardiac contractions are produced due to an electrical phenomenon called depolarization, that takes place in the heart muscles' cells (myocardial cells).

The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to (and stimulate) the myocardium (Cardiac muscle). Th...

This initial phase of the action potential is called the depolarization phase. Now as the depolarization phase progresses, the status of the two physical forces that have been discussed changes.
