124 天前 - High-degree atrioventricular node block is a known cause of bradycardia. Heart
rate and QT interval have an inverse relation. Therefore, bradycardia can lead to prolonged
QT interval, which can predispose patients to Torsades de Pointes, a life-threatening
arrhythmia. Correcting the underlying etiology can often reverse the arrhythmia and prevent
recurrence. For this reason, recognizing the etiology of this arrhythmia plays an essential
role in management.
