Abstract:
Objective Accelerated junctional rhythm (AJR) always occur during slow pathway catheter ablation for atrioventricular nodal reentrant tachycardia (AVNRT), the clinical significance of it has not been gotten in agreement. The aim of this study is to search for an association between AJR and ablation target site or tachycardia recurrence.Methods The data of 247 patients with AVNRT who received radiofrequency ablation procedure during April 1995 to October 1999 was analyzed. All these people were divided into two groups (212 patients in the successful ablation group or group 1, 35 patients in the recurrence group or group 2). The AJR was divided into two distinct pattern:type Ⅰ(continuous AJR that persisted until the end of energy delivery) and type Ⅱ (intermit AJR alternated with sinus rhythm during slow pathway ablation, which was eliminated immediately when stopping energy delivery ). Results\ The results showed that patients in group 1 exhibited better AJR response, most of them were seen with type Ⅱ AJR. However most of the people in group 2 had no AJR response throughout energy delivery , few of them had type Ⅰ AJR response. The AJR response of group 1 started relatively earlier than that of group 2(3 2?1 8 vs 5 7?2 5 ,P
