ABSTRACT
18 patients with atrioventricular nodal reentant tachycardia (AVNRT)and 5 patients with atrioventricular reentrant tachycardia (AVRT) with AVN double pathway (AVNDP) received radiofrequency ablation of slow pathway with inferior approach in order to modify AVN. AVNRT was induced in slow-fast form in 16 patients, in fast-slow form in one patients,and in coexistent slow-fast and fast-slow forms in one patients. Selective ablation of slow pathway was achieved in 18 patients. AVRT was induced in 5 patients (one obvient accessory pathway, 4 concealed accessory pathways) ,4 patients with reentrant cirucit of consisting of anterograde conduction by slow pathway of AVN and retrograde conduction by accessory pathway (AP) , one patient coexistent AVRT and AVNRT. Slow pathway in 5 patients and AP in 3 patients were successfully ablated. Junctional rhythm appeared in 21 patients during duation of discharge of radiofrequency current. No severe complicationwere noted. AVNRT in one patient recurred during a follow-up period of 1 to 15 months. The patient experienced second catheter ablation and was successed. It was suggested radlofrequency ablation of slow pathway with Inferior approach may be a method with high rate of success and less complication.
