Definitions:

Ventricles Repolarize

The process by which the heart's ventricles return to their resting state after contraction, crucial for heart rhythm.

Pacemaker Potential

The self-generated electrical potential that triggers the spontaneous depolarization of cells in the heart's pacemaker regions, leading to heartbeat regulation.

Depolarization

A reduction in the difference of electric potential across a cell membrane, leading to the possibility of producing an action potential.

Repolarization

The process by which cells restore their resting negative membrane potential after depolarization.
