摘　　要：用低功率射频导管消蚀（ＲＦＣＡ）房室交界区治疗室上性心律失常８例，其中消蚀房室结治疗起搏器术后顽固性快速心房颤动２例，改良房室结消蚀慢径路治疗房室结折返性心动过速６例。全部获得成功。平均输出功率（１９．１±３．１）Ｗ，阻抗稳定，碳化现象少，术后心肌酶基本正常。提示：低功率ＲＦＣＡ是一种安全、有效的治疗室上性心律失常的方法。Eight patients with supraventricular tachycardia were successfully treated by low power radiofrequency catheter ablation (RFCA). Atrioventricular (AV) node ablation was given in 2 patients planted pacemaker with recurrent rapid atrial fibrillation. Modification of AV node in the slow pathway was given in the other 6 patients with AV node reentry. During RFCA , the average power outlput was 19. 1W±3. 1W, the impedance was stable and carbonization was slight. After RFCA , the level of myocardial enzymes remained in the normal range. It has been suggested that low power RFCA is a safe and effective method for treating supraventricular tachythymia.
