Definitions:

Arrhythmias

Irregular heartbeats resulting from abnormalities in the heart’s electrical impulses, which can affect heart function.

Isovolumetric Contraction

A phase of the cardiac cycle during which the ventricles contract with no change in blood volume, because all heart valves are closed.

Pressure

The force exerted by a substance per unit area on another substance or on a surface, measured in units such as Pascals.

Ventricular Repolarization

The process by which the heart's ventricles return to their resting state after contraction, indicated by the T-wave in an ECG.
