房室结双径路构成房室结折返性心动过速(AVNRT),占阵发性室上性心动过速的第二位,仅次于旁道参与的房室折返性心动过速。其发病不受年龄、性别限制,且具复发倾向,历经数10年,药物仅能控制发作而不能根治。曾用直流电消融、手术治疗等,但并发症多、创伤大,接受治疗者甚少。自开展射频消融术后,AVNRT的根治已初见成效,治愈率可达90％～95％,因此在临床上应积极地推广此项技术,使更多的病人受益。但手术不当又可并发Ⅲ度房室传导阻滞(AVB),造成病人终生遗憾,故而手术要稳妥慎重。
Atrioventricular node dual pathway constitutes atrioventricular nodal reentrant tachycardia (AVNRT), accounting for paroxysmal supraventricular tachycardia second only to bypass participation in atrioventricular reentrant tachycardia. Its incidence is not subject to age and gender restrictions, and have a tendency to relapse, after 10 years, the drug can only control the attack and can not cure. Had used direct current ablation, surgery, etc., but the complications and trauma, receiving little treatment. Since the implementation of radiofrequency ablation, the cure of AVNRT has achieved initial success. The cure rate can reach 90% ~ 95%. Therefore, we should actively promote this technology in clinical practice to benefit more patients. However, inappropriate surgery can be complicated by Ⅲ degree atrioventricular block (AVB), causing patients regret for life, therefore, surgery should be prudent and discreet.
