摘　　要：用射频消融术治疗室上性心动过速80例.其中,房室折返性心动过速64例(65条旁路),56条左侧旁路中52条(92.9%)和9条右侧旁路中7条(77.8%)被阻断.14例房室结折返性心动过速(消融慢径)及2例房性心动过速和心房纤颤(消融房室结)均成功.比较初期30例和以后34例房室旁路病人的消融,显示了射频消融术开展过程中的学习曲线.此外,本文对预激综合征体表心电图旁路定位误差的原因,作了初步探讨.Eighty patients with supraventricular tachycardia were treated by radiofrequency catheter ablation. Among them, 64 patients with atrioventricular (AV) reciprocat-ing tachycardia had 65 AV accessory pathways (AP). Fifty-two of 56 (92. 9%) left -sided APs and 7 of 9 (77. 8%)right-sided APs were successfully abolished. In 14 patients with AV node reentrant tachycardia (ablating slow pathway) and 2 patients with atrial tachycardia of atrial fibrillation (ablating AV node), all the ablations succeded. A learning curve in this new technique was shown clearly by comparison of the ablative procedures in our initial 30 patients with APs with those of the suc-cessive 34 patients. The causes of mislocating AP accord-ing to the surface ECG in WPW syndrome patients were also analysed.
