射频消融术在快速心律失常中的临床应用

Clinical Application of Radiofrequency Ablation in Treating Patients with Rapid Arrhythmia

目的评价射频消融术治疗快速心律失常的临床疗效及安全性。方法分析我院施行射频消融术的19例快速心律失常病例的电生理特性、手术成功率和并发症。结果19例快速心律失常中,房室结折返性心动过速(AVNRT)8例;房室折返性心动过速(AVRT)10例,隐性旁道7例,显性旁道3例;左侧旁道8例,右侧旁道2例;双旁道1例;房速1例。经射频消融均获成功,无明显并发症。结论经导管射频消融治疗快速心律失常成功率高,且安全可靠,为目前治疗快速心律失常的首选方法。

Objective To evaluate the clinical curative effect and safety of radiofrequency ablation in treating patients with rapid arrhythmia. Methods The electrophysiological characteristics, the successful rate of operation and the complications of 19 eases with rapid arrhythmia being treated by radiofrequency ablation were analyzed. Result Out of the 19 cases, there were 8 eases with atrioventricular nodal reentrant tachycardia（ AVNRT）, 10 cases with atrioventricular reentrant tachyeardia（ AVRT ）, 7 cases with concealed pathway, 3 cases with manifest pathway, 8 cases with left accessory pathway, 2 cases with right accessory pathway, 1 case with dual accessory pathway and 1 ease with atrial tachyeardia; radiofrequeney ablation was successful in all the 19 eases and no obvious complications occurred. Conclusions Radiofrequency catheter ablation, as the first choice, is safe and reliable with high successful rate in treating patients with rapid arrhythmia.
