The QT interval is measured from the beginning of the QRS complex to the end of which wave?

Explanation:
QT interval measures the total time of ventricular electrical activity, from the start of ventricular depolarization to the end of ventricular repolarization. That means it begins with the onset of the QRS complex and ends at the end of the T wave. The P wave reflects atrial depolarization and isn’t part of this interval, the R wave is just a peak within the QRS, and the U wave, when present, occurs after the T wave and isn’t included in the standard QT interval.
