房室结折返性心动过速(AVNRT)是最常见的一种阵发性室上性心动过速,它产生于折返性环形传导,这个环路包括房室结快、慢径路。抗心律失常药不能总是成功地控制这种心律失常,射频消融快径路虽然能消除AVNRT,但可引起心脏阻滞。如果能够通过导管将慢径路消融,则既可消除AVNRT,又不损伤正常的(快径路)房室结传导。进入本研究的AVNRT患者80例,男24例,女56例,平均年龄41.7±17.5岁,有器质性心脏病者14例。这些患者的阵发性心动过速平均发作时间14.9±11.9年,曾用3.0±1.6种抗心律失常药治疗,效果不满意。射频消融前,给于芬太尼等镇静剂,使患者入睡;然后经右锁骨下和股静脉经皮穿刺,将5根电极
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common type of paroxysmal supraventricular tachycardia, which arises from reentrant circular conduction. This loop includes atrioventricular node fast and slow pathway. Antiarrhythmic drugs can not always successfully control this arrhythmia. Although RFA can eliminate AVNRT, it can cause heart block. If ablation of the slow pathway is via a catheter, AVNRT can be eliminated without compromising normal (fast track) AV node conduction. Enter the study of 80 patients with AVNRT, 24 males and 56 females, mean age 41.7 ± 17.5 years, 14 cases of organic heart disease. The average onset time of paroxysmal tachycardia in these patients was 14.9 ± 11.9 years, with 3.0 ± 1.6 antiarrhythmic drugs, the effect is not satisfied. Before radiofrequency ablation, to fentanyl and other sedatives, so that patients fall asleep; then by the right subclavian and femoral vein percutaneous, the five electrodes
