Prolonged QT-Interval Syndromes

JAMA: The Journal of the American Medical Association, 1986
PROLONGATION of the QT interval, either on a congenital or an acquired basis, is associated with an increased likelihood of malignant ventricular arrhythmias. 1-3 Patients with QT prolongation frequently develop recurrent attacks of syncope or may present with sudden death.

Hypocalcemia-Induced QT Interval Prolongation

Cardiology, 2022
An 87-year-old man with a history of transcatheter aortic valve replacement, pulmonary hypertension, diastolic dysfunction with preserved systolic function, and myelofibrosis had a 12-lead ECG showed a prolonged QT interval of 508 ms with heart-rate correction placing it in the 99th percentile of the population.

QT interval prolongation

The Journal of Emergency Medicine, 1985
The QT interval is a function of ventricular repolarization time and is measured from the onset of the QRS complex to the end of the T wave. The length of this interval is inversely related to heart rate. A prolonged QT interval is most often secondary to the use of Type I antidysrhythmic medications (quinidine, procainamide).

Syncope With Prolonged QT Interval

Archives of Pediatrics & Adolescent Medicine, 1976
Four 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.
