摘要
目的探讨射频消融术对频发单形室性早搏的疗效。方法对频发性室性早搏患者19例采取激动标测及起搏标测相结合,以起搏时与室性早搏QRS波形态完全相同点为消融靶点行射频消融治疗。结果18例即刻成功,1例无效,无并发症。术后2周24h动态心电图检测,随诊6个月至2年,17例无复发或早搏无增多,1例出现另一形态室性早搏。结论射频消融治疗频发单形室性流出道室性早搏安全、有效。
Objective To discuss curative effect about radio frequently catheter ablation（RFCA） in frequently single originating premature ventricular beats, Methods 19 patients with frequently single original premature ventricular beats. The site of orgin was determined by activation mapping for the earliest endocardial activation, and by pace mapping for the exact QRD pacing site. Results 18 patients operation obtained immediate success, 1 patient was failure, but no complication happened. After RFA in 2 weeks 24 hour Hoter ECG was used to examine arrhythmia condition,and all eases were follow up for 6-24 months after RFA, there were 17 patients who had no recurrence or phenomenon of premature beats augument, 1 patient showed other type premature ventricular bearts. Conclusion It is safe and effective about RFA in frequently single origin premature ventricular beats of outflow lane.
