Elimination of AV nodal reentrant tachycardia with 2:1 VA block by posteroseptal ablation

J Cardiovasc Electrophysiol. 1994 Jun;5(6):510-6. doi: 10.1111/j.1540-8167.1994.tb01291.x.

Abstract

AV nodal reentry capable of VA block during tachycardia was successfully eliminated using a posteroseptal ablation pulse delivered well away from the site of earliest atrial activation during tachycardia. A possible explanation is that the arrhythmia represented typical AV nodal reentrant tachycardia with transient intra-atrial conduction block during tachycardia.
