射频消融术(RFCA)是1991年国内用于治疗快速心律失常的介入性技术。自1993年3月~1994年5月,我们采用RFCA对11例房室结双径路(AVNDP)患者进行了房室结改良术,现对其疗效的观察报告如下。 1 资料与方法 1.1 临床资料 11例中,男8例,女3例;年龄36~62岁,平均50.4岁。心动过速史1~18年,平均9.5±6.2年。多数病例长期服用心得安、心律平、异搏定等药物不能预防发作。发作时多伴有头晕、黑朦、心悸等症状,术前经食道电生理检查或心内电生理检查,均证实为AVNDP,并诱发出房室结折返性心动过速(AVNRT)。 1.2 方法
Radiofrequency ablation (RFCA) is a domestic interventional technique used to treat tachyarrhythmias in 1991. From March 1993 to May 1994, we used RFCA to ameliorating 11 cases of AVNDP in patients with atrioventricular node. We report the following findings. 1 Materials and Methods 1.1 Clinical data 11 cases, 8 males and 3 females; aged 36 to 62 years, an average of 50.4 years old. Tachycardia history of 1 to 18 years, an average of 9.5 ± 6.2 years. Long-term use of the majority of cases of safety, heart rate, verapamil and other drugs can not prevent the attack. More often accompanied by symptoms of dizziness, darkness, palpitations and other symptoms, preoperative transesophageal electrophysiological examination or electrophysiological examination were confirmed as AVNDP, and induce atrioventricular nodal reentrant tachycardia (AVNRT). 1.2 method
