Related to QRS interval: QT interval. the duration of the QRS complex in the electrocardiogram. In the electrocardiogram, the interval that denotes depolarization of the ventricles, between the beginning of the Q wave and the end of the S wave. Its normal duration is 120â200 msec. Shorter durations are found, e.g., in preexcitation. Longer durations are indicative of first-degree heart block.
where QTcB is the QT interval corrected for heart rate, and RR is the interval from the onset of one QRS complex to the onset of the next QRS complex, measured in seconds, often derived from the heart rate (HR) as 60/HR (here QT is measured in milliseconds).
