经导管射频消融治疗１５例阵发性室上性心动过速（ＰＳＶＴ）患者。宽ＱＲＳ心动过速１例，同时有宽及窄ＱＲＳ心动过速１例，单纯窄ＱＲＳ心动过速１３例。显性预激６例，其中Ａ型预激４例，Ｂ型预激２例，１２例为单一旁道，１例为房室结４径路所引起的慢－快型房室结折返性心动过速（ＡＶＮＲＴ），１例为３条旁道，１例为２条旁道同时合并有房室结双径路所引起的慢－快型ＡＶＮＲＴ。１７条旁道的部位分布如下：右前间隔１条，右中间隔３条，右后间隔４条，左后间隔３条，左游离壁２条，右正后游离壁２条，右后外游离壁１条，右前游离壁１条。射频治疗后１７条旁道的前传及逆传全部阻断，２条旁道并有房室结双径路病人的２条旁道均阻断，其房室结双径路的前传快径与逆传快径亦被阻断，房室结４径路病人的３条慢径中的１条阻断，在用异丙肾的条件下全部病人均不能诱发心动过速。手术时间为２－８ｂ，平均４ｂ。放电次数２－４０次，平均１９次，右侧旁道占７１．０％，多旁道占１３．０％，射频成功率为１００％，无严重并发症。
Transcatheter RFA for 15 patients with paroxysmal supraventricular tachycardia (PSVT). 1 case of wide QRS tachycardia, while wide and narrow QRS tachycardia in 1 case, simple narrow QRS tachycardia in 13 cases. Six cases were dominant pre-excitation, including 4 cases of type A pre-excitation, 2 cases of type B pre-excitation, 12 cases of single bypass and 1 case of slow-fast atrioventricular nodal reentrant cardioversion caused by atrioventricular node 4 pathways (AVNRT), 1 case of 3 bypass, 1 case of 2 bypass concurrent with atrioventricular node dual pathways caused by slow - fast AVNRT. The distribution of the 17 accessory pathways is as follows: 1 anterior right, 3 anterior middle, 4 anterior right, 3 anterior left, 2 left anterior wall, 2 anterior right posterior free wall, 1 wall, 1 free wall right front. Radiofrequency treatment of 17 bypass pre-pass and reverse all blocked, 2 bypass and atrioventricular node dual pathways in patients with two bypass were blocked, the AV channel anterior fast pathway and reverse transmission Fast track was also blocked, a pathway in the atrioventricular node 4 pathways blocked by one of three slow pathway, all patients under the condition of isoproterenol can not induce tachycardia. Surgery time is 2-8b, with an average of 4b. The number of discharges was 2-40 times, with an average of 19 times. The right side access accounted for 71.0%, the multi-side access 13.0% and the radio frequency success rate was 100% without serious complications.
