Radiofrequency catheter ablation of an intraatrial reentrant tachycardia: evidence of an area of slow conduction.
Radiofrequency catheter ablation for intraatrial reentrant tachycardia has not been previously reported. This article describes a patient with a demonstrable area of slowed conduction in the lateral right atrium that responded to radiofrequency catheter ablation in the area of the fractionated electrogram with elimination of the tachycardia. This patient also had the common form of atrioventricular nodal reentrant tachycardia, which was also successfully ablated.
