WebIt is measured from the onset of the QRS complex to the end of the T-wave. The QT duration is inversely related to heart rate; i.e the QT interval increases at slower heart rates and decreases at higher heart rates. Therefore to determine whether the QT interval is within normal limits, it is necessary to adjust for the heart rate.
