C)P wave

Question

Quizplus · Accepted Answer

The P wave on the ECG follows the firing of the sinoatrial (SA) node, which is responsible for initiating the heartbeat by causing the atria to contract. The P wave represents the electrical depolarization of the atria as they begin to contract. The QRS wave represents the depolarization of the ventricles, while the T wave represents their repolarization.
