Which ECG waveform represents ventricular repolarization?

Explanation:
Ventricular repolarization is the ventricles resetting after contraction, and on the ECG this recovery phase is shown by the T-wave. The P-wave reflects atrial depolarization, the QRS complex reflects ventricular depolarization, and NSR refers to a normal rhythm, not a specific waveform. So the rounded, after-the-QRS deflection—the T-wave—represents ventricular repolarization.
