Action potential the generation of an action potential is caused by depolarization of the membrane beyond threshold “all-or-none” event chain reaction. An action potential is a pulse-like wave of voltage that can like the resting potential, action potentials depend upon the permeability of the (about 2 µ.
The cardiac action potential is a brief change in voltage (membrane potential) across the cell membrane of heart cells this is caused by the movement of charged.
