The P wave in the ECG represents atrial depolarization, which results in atrial contraction.
QRS complex has the largest amplitude and is produced by depolarization of the ventricles and somewhat insignificant repolarization of the arteries. P wave is produced during depolarization of the atria and should come before the QRS complex. T wave is produced during repolarization of the ventricles and comes after the QRS complex. 5. The P wave and the QRS complex represent depolarization of the atrial and ventricular muscle, respectively. Explain anatomically and physiologically why the QRS complex has a larger amplitude.
