A Case of Successful Ablation of Right-Sided Accessory Pathway during Atrial Fibrillation

Abstract

The occurrence of atrial fibillation during an electrophysiologic study or catheter ablation in patients with accessory pathways is a common problem and sometimes complicates the localization and ablation procedure of accessory pathways. In patients with sustained atrial fibrillation, it is often time-consuming to terminate atrial fibrillation by drugs or electrical cardioversion. We performed successful radiofrequency catheter ablation in a patient with right-sided accessory pathway during atrial fibrillation requiring repeated electrical cardioversion. The target site was determined by activation mapping and morphology of unipolar electrogram at a site of early ventricular activation.
