Verified
During the cardiac cycle, ventricular depolarization and repolarization both begin at the apex of the heart and progress superiorly.
Ventricular Depolarization
The electrical activity that triggers contraction of the ventricles, the heart's lower chambers, during the cardiac cycle.
Ventricular Repolarization
is the process of restoring the heart's ventricles to their resting state after contraction, depicted as the T wave on an ECG.
Cardiac Cycle
The sequence of events that occur in the heart during one heartbeat, including systole and diastole phases.
