显性多旁道的电生理特点和射频消融治疗

目的报道显性多旁道的心电生理特点和射频消融治疗。方法回顾性分析70例显性多旁道患者的一般临床资料、旁道分布特点、心动过速类型及消融治疗的效果。结果①70例均有心动过速发作史,29例有2种、6例有3种心动过速;②70例共有158例显性旁道,18例为3条旁道,52例为2条旁道;③61例可诱发AVRT,其中13例为逆向型AVRT;④消融患者的成功率为97.1%(68/70例),消融的旁道成功率为98.7%(156/158条)。结论显性多旁道易发生多种心动过速,射频消融治疗成功率高。

Electrophysiological characteristics and radiofrequency ablation of manifest multiple accessory pathways

Objective To report the electrophysiological characteristics and radiofrequency ablation of manifest multiple accessory pathways. Methods We reviewed the clinical data and characteristics of accessory pathways distribution and results of radiofrequency catheter ablation in 70 patients with multiple accessory pathways. Results ① 70 patients all had tachycardia history, 29 had two, 6 had three kinds of tachycardias; ② A total of 158 manifest accessory pathways were detected in these 70 patients, 52 had two, 18 had three accessory pathways; ③ AVRT could be induced in 61 patients, including 13 cases of antidromic-AVRT; ④ The success rate of the radiofrequency ablation of the patients′ was 97.1%(68/70), while accessory pathways′success rate was 98.7%(156/158). Conclusion Manifest multiple accessory pathways are vulnerable to a variety of tachycardias, radiofrequency ablation for the treatment with a high success rate.
