Catheter radiofrequency ablation of slow pathway in patients with atrioventricular nodal re-entrant tachycardia.
Selective ablation of slow pathway by radiofrequency current in 12 patients with atrioventricular (AV) nodal dual pathway and tachycardia was performed in our section. A large-tip ablation catheter was positioned around the ostium of the coronary sinus. The slow pathways of all the 12 patients were abolished permanently. Both the antegrade and retrograde conduction of fast pathway was not affected. There was no recurrence after 178 days follow-up.
