Action Potentials and The Cardiac Cycle
...contraction. Seeley, Stephens, and Tate (2007) further explicated that action potentials in cardiac muscles, just like the skeletal muscles and neurons, are characterized by depolarization followed by repolarization, only that cardiac muscles do have a period of slow repolarization, which, in turn, causes a prolongation of the action potential. Moreover, action potentials... ).
Repolarization OR the Early Repolarization Phase
During this phase, the Na+ channels close, at the same time, some K+ channels open, thereby causes early repolarization (Seeley, Stephens, and Tate, 2007: 333).
