Retrograde fast pathway ablation for atrioventricular nodal reentry associated with markedly prolonged PR intervals

Am J Cardiol. 1999 Feb 1;83(3):455-8, A9-10. doi: 10.1016/s0002-9149(98)00887-x.

Abstract

Three patients with typical atrioventricular nodal reentrant tachycardia (AVNRT) and markedly prolonged PR intervals (>300 ms) without dual pathway physiology at baseline or during isoproterenol infusion underwent successful fast pathway ablation and remained asymptomatic without recurrent AVNRT, atrioventricular block, or symptomatic bradycardia for a mean of 19 months. In patients with recurrent AVNRT and markedly prolonged PR intervals, selective ablation of the retrograde fast pathway can eliminate AVNRT without further impairment of anterograde atrioventricular nodal function.
