本文总结了 6 4例阵发性室上性心动过速的射频消融治疗 ,其中房室折返性心动过速 (AVRT) 4 4例 ,包括左前侧壁旁路 13例 ,左侧游离壁旁路 15例 ,左后侧壁旁路 2例 ,左后间隔旁路 8例。右后间隔旁路 4例 ,右后壁旁路 2例 ;房室结折返性心动过速 (AVNRT) 2 0例 ;既有旁路 ,又有双径路 1例 ;两条旁路 1例。以导管射频消融阻断旁路及改良房室结构 ,成功率98 4% ,1例出现Ⅲ°房室传导阻滞 ,1例复发 ,再次射频消融后治愈。 This article summarizes 64 cases of paroxysmal supraventricular tachycardia radiofrequency ablation treatment, including atrioventricular reentrant tachycardia (AVRT) 44 cases, including left anterior lateral wall bypass in 13 cases, the left aortic wall bypass 15 cases, 2 cases of left posterior wall bypass, 8 cases of left posterior septal bypass. Right posterior spacer bypass in 4 cases, right posterior bypass in 2 cases; atrioventricular nodal reentrant tachycardia (AVNRT) 20 cases; both bypass and a double-track in 1 case; two bypass in 1 case. Radiofrequency catheter ablation of bypass and improve the atrioventricular structure, the success rate of 98 4%, 1 case of Ⅲ ° atrioventricular block, 1 case of recurrence, again after radiofrequency ablation and cure.
