Definitions:

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.

Cardiac Muscle Cells

Specialized muscle cells found in the heart that contract rhythmically and involuntarily to pump blood throughout the body.
