C) T wave.
D) J point.

Question

Quizplus · Accepted Answer

Ventricular depolarization is represented on the ECG by the QRS complex, which reflects the electrical activity of the ventricles contracting. The P wave represents atrial depolarization, while the T wave represents ventricular repolarization. The J point is the junction between the QRS complex and the ST segment and does not represent ventricular depolarization.
