ECG Wave Patterns

- ECG Wave Patterns Wave Pattern Corresponding Heart Activity Electrical Activity P Wave Atrial contraction that is initiated by an electrical Atrial depolarization impulse from the SA node QRS Complex ‘ Ventricular contraction of the heart Ventricular depolarization T Wave Completion of ventricular contraction; here, the Ventricular repolarization cells begin their resting phase before the process restarts U Wave ‘ Sometimes present and represents further relaxation A continuation of ventricular repolarization of the ventricles
