A. Atrial depolarization B. Atrial repolarization C. Ventricular depolarization D. Ventricular repolarization

Correct Answer is A

Explanation

A. The P wave on an ECG represents atrial depolarization, which occurs as the electrical impulse originates in the sinoatrial (SA) node and spreads through the atria, initiating atrial contraction.
B. Atrial repolarization typically occurs during the QRS complex and is not represented by the P wave. Atrial repolarization is masked by the larger QRS complex.
C. Ventricular depolarization is represented by the QRS complex on an ECG, as the electrical impulse spreads through the ventricles, leading to ventricular contraction.
D. Ventricular repolarization typically occurs during the T wave and is not represented by the P wave. Ventricular repolarization involves the recovery of ventricular muscle cells after contraction.
