摘要
目的评价慢径改良术治疗房室结折返性心动过速(AVNRT)的远期疗效和安全性。方法57例慢径改良术后的AVNRT患者[男性20例,女性37例,平均年龄(46.5±12.3)岁]接受了随访研究,平均随访时间(36±24)个月,随访内容包括:心电图和24h动态心电图P-R间期、食管电生理房室结前传有效不应期(AVN-ERP)、1∶1房室传导的最大频率、心动过速复发率、并发症发生率以及生活质量等。结果本组患者慢径改良成功率96.5%(55/57),复发率5.5%(3/55),其中术后3个月内复发1例,6个月以上复发2例。Ⅰ度房室传导阻滞经心电图证实为1例(1.8%),经Holter检测为6例(10.9%)。Ⅱ度房室传导阻滞1例,远期随访未发现Ⅲ度房室传导阻滞。射频消融后AVN-ERP延长,1∶1房室传导的最大频率减慢。93.1%的患者远期随访无不适主诉。结论远期随访表明,射频消融房室结慢径治疗AVNRT是安全、有效的,提高了患者的生活质量。
Objective To evaluate the long-term results of catheter modification of the slow pathway for the treatment of atrioventricular nodal reentrant tachycardial （AVNRT）. Methods The study included 57 patients [20 men and 37 women, mean age （ 46.5±12.3 ）years ]. After modification, the patients were followed up for a mean of （36±24）months. PR interval of electrocardiogram and Holter monitoring, the effective refractory period of AV node and the maximum rate of one to one AV conduction, AVNTR recurrence, complications and quality of life were investigated during the follow-up. Results The success rate was 96.5% （55/57）, and the AVNRT recurrence was 5.5% （3/55） after catheter modification of the slow pathway, in which 1 patients in three months and 2 patients more than 6 months developed AVNRT recurrence after the procedure. There was first-degree AV block in 1 patiens （1.8%）,which was demonstrated by electrocardiogram and in 6 patients （10.9%）, which was observed during Holter monitoring.Second-degree AV-block occurred in 1 patients.No patient with third-degree AV block was foud during the long-term follow-up. The effective refractory period of AV node prolonged and the maximum rate of one to one AV conduction slowered. 93.1% patients were free of symptoms after the procedure. Conclusion Catheter modification of the slow pathway is a safe and effective therapy for the treatment of patients with AVNRT. During a long-term follow-up patients have improved quality of life after the procedure.
