摘要
对47例室上性心动过速患者做了射频消融术,其中1例未成功,计46例。房室结双径路15例,隐匿性房室旁路17例,W-P-W综合征14例。46例病人中,右侧隐匿性旁路1例,B型W-P-W综合征3例,A型合并B型W-P-W综合征1例。结果提示,房室结双径路应选择慢径消融,消融后一旦慢径路消失,即表明消融成功。而波消失或心室起搏时表现室房分离或递减传导,即为旁路消融成功的标志。房室结双径路消融成功后一般不必要巩固放电,而旁路消融成功后可以再巩固放电1~2次。消融术后系统的电生理检查是必要的。
The successful radiofrequency catheter ablations for 46 patients with paroxysmal supraventricular tachycardia (SVT) were performed,in which there were 15 cases with atrioventricualr nodal dual pathways,17 with, concealed atrioventricular accessory pathway and 14 with W-P-W syndrome. The results suggested that the ablations of slow-pathways should be selected in patients with atrioventricular nodal dual pathway and the success of ablation was showed by disappearence of slow-pathway. It proved successful ablations that delta waves disappeared in electrocardiograms and the dissociations of ventriculoatrial conduction or ventriculoatrial decremental conductions could be seen during rapid ventricular pacing in patients with overt or concealed atri-oventricular accessory pathway. It was necessary that patients with paroxysmal SVT should receive clinical and electrophysiological evaluations after the ablations.
