Overview

AV nodal reentrant tachycardia can be caused by Lown-Ganong-Levine syndrome, Mahaim fiber tachycardia, mitral valve prolapse, tachycardia mediated cardiomyopathy and Wolff-Parkinson-White syndrome. It has also been reported to have a familial etiology.[1]

Causes

Life Threatening Causes

Life-threatening causes include conditions which result in death or permanent disability within 24 hours if left untreated.

AV nodal reentrant tachycardia is usually not life-threatening.
