WebThe P Wave: The P wave of an electrocardiogram (EKG or ECG) represents the depolarization (i.e., contraction) of the atrial muscles. The atria are the top two chambers of the heart. When these muscles contract, the atria pump blood into the bottom two chambers of the heart which are the ventricles. Answer and Explanation: 1
