WebQRS complex = depolarization of ventricles, consisting of the Q, R, and S waves. QT interval = time interval between onset of ventricular depolarization and end of ventricular repolarization. R-R interval = time interval between 2 QRS complexes. T wave = ventricular repolarization. ST segment plus T wave (ST-T) = ventricular repolarization. is ellingham academy real https://sixshavers.com
