Which statement correctly identifies the T Wave in relation to ventricular activity?

Explanation:
Understanding what the T wave shows on an ECG comes down to the sequence of ventricular electrical activity. After the ventricles depolarize and contract (shown by the QRS complex), they need to reset electrically in preparation for the next beat. This recovery phase is ventricular repolarization, and it appears as the T wave. So the T wave correctly identifies the ventricles’ return to their resting electrical state. For context, the P wave reflects atrial depolarization, while the QRS complex marks ventricular depolarization.
