We report a case of a 63-year-old women with Chagas' disease and recurrent, syncopal VT treated by RF catheter ablation in whom endocardial application of RF energy was guided by nonsurgical epicardial mapping. The procedure was undertaken in the electrophysiology laboratory under deep anesthesia. VT was interrupted after 2.4 seconds of application and rendered noninducible afterwards. Two weeks after the procedure, a distinct morphology VT was induced by programmed ventricular stimulation, and the patient was started on amiodarone, remaining asymptomatic 12 months after the procedure.
我们报告了一例63岁患有恰加斯病且反复出现晕厥性室性心动过速（VT）的女性患者，其通过射频导管消融治疗，术中的心内膜射频能量应用由非手术的心外膜标测引导。该手术在深度麻醉下于电生理实验室进行。射频能量施加2.4秒后室性心动过速被打断，之后不能再诱发。术后两周，程序性心室刺激诱发了一种形态不同的室性心动过速，患者开始服用胺碘酮，术后12个月仍无症状。
