摘　　要：报道24例病人经射频消融(RFCA)慢径改良房室结治疗房室结折返性心动过速(AVNRT)的研究结果。RFCA后24例病人均不再诱发AVNRT(100％),其中23例慢径传导消失(95.8％),1例慢径传导明显减慢(4.2％)。认为RFCA改良慢径对房室和室房传导没有明显影响,其消融成功的可能预测指标为:X线影象消融电极位于房室结后下部、消融电极图A/V<0.4,放电出现交界性早搏或并行性交界性心律。This article reported the result of catheter ablation of slow pathway using radiofrequency energy to treat atrioventricular nodal reentrant tachycardia (AVNRT) in 24 patients. AVNRT couldn't induced in all patients after ablation. Slow pathways were eliminated in 23 patients and the conduction of slow pathway was longer in one patient after ablation. It suggested that radiofrequency catheter ablation of slow pathway not effect antegrade and retrograde conduction of node and the indication of successful ablation might be the ablation electrode localized at postero-inferior of atrioventicular node,A/V<0.4 in local recording and junctional premature beat or junctional parasystole during ablation.
