WebThe QT interval is a measurement that represents the total time from ventricular depolarization to complete repolarization. This process begins at the start of the q wave and extends to the end of the T wave. If there is no q wave, then the starting point would be the very beginning of the R wave. The QT interval is affected by many things. WebThe QT interval is defined as the time duration between the onset of the QRS complex and the end of the T wave as it returns to baseline ( fig 2 ), ideally measured using either lead II or lead V5 of the 12-lead ECG.
