The bioelectric activity of the myocardium during the excitation process, also called depolarization phase, is associated with a propagating front-like variation of the transmembrane potential which is the jump of the potential across the cellular membrane. In this phase the transmembrane potential undergoes an abrupt change from a resting to an excited value occurring in a moving layer about 1 mm thick and lasting about 2 msec.
