Definitions:

Action Potential Propagation

The process by which an electrical impulse travels along the membrane of a neuron or muscle fiber, enabling the transmission of signals over long distances within the body.

Intercalated Discs

Specialized connections between cardiac muscle cells containing gap junctions and desmosomes, allowing rapid transmission of electrical impulses.

Plateau Phase

A phase during the action potential of cardiac muscle cells characterized by sustained depolarization, contributing to the lengthening of cardiac muscle contraction.

Abnormal Heart Rhythm

Refers to irregular heartbeats or arrhythmias, which may disrupt the normal flow of blood through the heart.
