Normal P Wave Size … WebbThe 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 philippine statistics on mental healthWebbFigure 19.3.2 – Relationship between the Cardiac Cycle and ECG: Initially, both the atria and ventricles are relaxed (diastole). The P wave represents depolarization of the atria and is followed by atrial contraction (systole). Atrial systole extends until the QRS complex, at which point, the atria relax. tru north carolina
