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.

  • Describe the process and importance of ventricular contraction and relaxation within the cardiac cycle.

Final Answer :
True
Explanation :
Ventricular depolarization (QRS complex) starts at the apex and progresses superiorly, followed by ventricular repolarization (T wave) in the same direction.
