Complex Electrophysiological Characteristics in Atrioventricular Nodal Reentrant Tachycardia With Continuous Atrioventricular Node Function Curves

Abstract

In AVNRT with continuous AV node function curves, dual AV nodal pathway physiology may or may not be demonstrated during atrial pacing. Significant shortening of the maximal AH interval during atrial pacing after radiofrequency ablation suggests successful elimination of AVNRT.
