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

The QT interval reflects the total time for the ventricles to activate and then recover. It starts with the beginning of ventricular depolarization (the start of the QRS complex) and ends at the end of ventricular repolarization (the end of the T wave). The P wave shows atrial depolarization, and the U wave is not part of the standard QT measurement, while the R wave is just a portion of the QRS complex. So the endpoint is the end of the T wave.
