SA Node

The sinoatrial node, a group of cells located in the right atrium of the heart that initiates the electrical impulses governing the heart rate, often considered the heart's natural pacemaker.

The process by which the resting potential of a cell membrane becomes less negative, leading to the initiation of an action potential.

Heart Rate

The number of heartbeats per unit of time, usually measured in beats per minute (bpm), indicating the heart's workload and overall cardiovascular health.

Plateau Phase

A phase in some action potentials, notably in cardiac muscle cells, characterized by sustained depolarization that prolongs the action potential.
