Unformatted text preview: The P wave is a small wave that represents the depolarization of the atria. During this wave, the muscles of the atria are contracting. • The QRS complex is a rapid down-up-down movement. The upward movement produces a tall peak, indicated by R. The QRS complex represents the depolarization of the ventricles. • The T wave represents the repolarization of the ventricles. Electrical activity generated by the repolarization of the atria is concealed by the QRS complex....
