【摘要】 目的 :观察射频治疗室性心律失常的疗效 ,以替代抗心律失常药物。方法 :利用体表心电图 12导联定位及心内电生理标测进行射频消融治疗室性早搏 2 1例。结果 :体表心电图可基本确定其发生部位 ,射频电极标测室性早搏提前时间在 2 0～ 40 ms,并局部起搏图形与室性早搏一致 ,采用 12～ 40 W,3～ 7m in消融 ,成功率 86%。根据Holter随访具有统计学意义 ( P<0 .0 1)。结论 :只要标测定位准 ,其疗效是肯定的 ,可部分或基本替代抗心律失常药物 ,并避免药物所致的副作用更多还原

【Abstract】 AIM: To evaluate the radiofrequency ablation in the treatment of ventricular arrhythmia instead of antiarrythmic drug. METHODS: Radiofrequency ablation was performed in 21 patients by endocardial electrophysiologic examination and by surface ECG lead 12 location. RESULTS: These 21 cases demonstrated that surface ECG could basically locate the ventricular premature beat,which could be detected 20~40 ms ealier than by normal radiofrequency electrode, and the focal pacing figure is consistant to the ventricular premature beat. Radiofrequency ablation was performed by 12~40 W, 3~7 min, and proved effective in 86% of the patients. This investigation showed statistic meaning followed by Holter ( P <0.01). CONCLUSION:This technique is effective on condition that the location is precise and it can be used as a substitute for antiarrythmic drug to avoid side effects.更多还原
