Closed-Chest Ablation of Retrograde Conduction in Patients with Atrioventricular Nodal Reentrant Tachycardia

Abstract
We applied a new technique of catheter ablation to treat atrioventricular nodal reentrant tachycardia and preserve anterograde conduction, performing this procedure in 21 patients with repetitive episodes of tachycardia refractory to antiarrhythmic drugs.
