C)P wave (atrial depolarization),QRS complex (ventricular depolarization),T wave (ventricular repolarization)
D)P wave (atrial depolarization),QRS complex (ventricular depolarization),T wave (atrial depolarization of the next cycle)
E)P wave (atrial contraction),QRS complex (ventricular contraction),T wave (ventricular relaxation)

Question

Quizplus · Accepted Answer

The correct features of the ECG are: P wave (atrial depolarization), QRS complex (ventricular depolarization), and T wave (ventricular repolarization). The P wave represents the electrical activity of the atria, the QRS complex represents the electrical activity of the ventricles, and the T wave represents the recovery phase of the ventricles as they repolarize. Option C is the only one that has these correct representations of the cardiac cycle.
