Question

Quizplus · Accepted Answer

Ventricular systole is not displayed as the QRS on the ECG. The QRS complex represents the depolarization of the ventricles, which precedes ventricular systole. Ventricular systole begins at the end of the QRS complex and continues until the beginning of the T wave, which represents ventricular repolarization and the beginning of ventricular diastole.
