Practice questions based on extended ECG mechanics.
Q1. Assertion (A): In an ECG, the T-wave represents the repolarization of the ventricles. Reason (R): Repolarization means the ventricular muscle is returning to its resting electrical state, signaling the end of ventricular contraction (systole) and the beginning of relaxation (diastole).
