In cardiology theQT intervalis measured time between the start of the Q wave and the end of T wave on the electrocardiogram.
If it is abnormally prolonged it can generate ventricular arrhythmias.
The QT interval is dependent on the heart rate (the higher frequency the shorter the interval) and it has to be adjusted to that frequency for its interpretation.
