Sequential Anterograde and Retrograde Conduction Block during Radiofrequency Ablation of an Accessory Pathway

Abstract

We present an interesting image showing sequential loss of anterograde, and subsequently, retrograde conduction during radiofrequency ablation of an accessory pathway. We discuss the possible mechanisms and prior literature concerning this interesting finding.
