What happens during the P Wave?

Explanation:
During the P wave, the atria are depolarizing. This electrical activation starts at the Sinoatrial node and spreads through the atrial muscle, triggering atrial contraction. The ventricles then depolarize during the QRS complex, and the ventricles repolarize during the T wave. Atrial repolarization does occur, but it is masked by the larger ventricular depolarization, so it isn’t seen as a separate wave.
