| 摘 要： | 目的探讨老年慢-快型房室结折返性心动过速(AVNRT)患者射频消融(RFCA)治疗的特点。方法慢-快型AVNRT患者老年组28例，非老年组63例，采用中位法消融房室结慢径。结果两组的手术成功率、复发率及并发症发生率差异均无显著性，但老年组有效消融功率为(25.1±10.1)w，对照组为(19.9±9.1)w(P＜0.05)；消融时间老年组为(332.3±144.7)s，对照组为(268±88.2)s，老年组高于非老年组(P＜0.05)。结论RFCA治疗老年AAVNRT患者安全有效，但需较高的消融能量(消融功率和放电时间)。

| Abstract: | To analyze the characteristics of radiofrequency catheter ablation(RFCA)in elderly patients with atrioven tricular node reentrant tachycardia(AVNRT). Methods: Twenty-eight elderly patients and 63 young patients with AVNRT were treated with slow atrioventricular node pathway ablation. Results: The energy were (25.1+10.1) w and (19.9+9.1) w, and radiiofrequency application time were (332.3+144.7) s and (268+88.2) s in elderly and young patients respectively(P＜0.05). They were sigrnificant higher in elderly patients than that in young patients. There was no significant difference between two groups in success rate,recurrence rate and complications. Conclusion: RFCA is an effective and safe method in treating AVNRT for elderly patients. Higher effective radiofrequency energy is needed. |
