The QT interval of the electrocardiogram (ECG) is measured from the onset of ventricular activity to the end of the T wave. Because the QT interval varies with heart rate in normal individuals a “corrected” QT interval is sometimes calculated to factor out heart rate-dependent effects to provide a measure that is independent of rate effects.

Syncope With Prolonged QT Interval
Archives of Pediatrics & Adolescent Medicine, 1976Four children with syncope had a prolonged QT interval on the electrocardiogram. Neurologic studies were negative. One patient had associated deaf mutism, one had a family history of sudden death and prolonged QT interval, and two had ventricular arrhythmias while being monitored in the hospital.

THE QT INTERVAL AND CARDIAC ARRHYTHMIAS
Annual Review of Medicine, 1987The relation between the QT interval, ventricular arrhythmias, and dispersion of ventricular repolarization is reviewed. Conditions associated with prolonged QT interval in clinical practice are listed and discussed briefly. There is no conclusive evidence that prolonged QT is an independent prognostic marker in patients with coronary and other types ...
