射频导管消融治疗非器质性心脏病患者的顽固性频发室性早搏

Radiofrequency Ablation of Refractory and Frequent Premature Ventricular Contractions in Patients Without Organic Heart Disease

目的 :报道顽固性频发室性早搏的射频导管消融治疗结果。 方法 :采用起搏标测法 ,射频导管消融治疗 12例非器质性心脏病患者的顽固性频发室性早搏。 结果 :12例患者均消融成功 ,平均放电 3.2± 2 .3次。术后室性早搏总数由术前的 2 86 17± 42 88个 /天减至0～ 2个 /天 ,患者症状基本消失。随访 12个月 ,室性早搏≤ 5个 /天。 结论 :射频导管消融可用于药物治疗无效而症状明显的频发单形性室性早搏。

Objective:To report an experience of radiofrequency ablation for patients with refractory premature ventricular contractions. Methods:With pace mapping method,radiofrequency ablation was used to eliminate drug refractory and frequent premature ventricular contractions in twelve patients without organic heart disease. Results:Frequent premature ventricular contractions were successfully ablated in all patients with mean 3.2±2.3 radiofrequency applications.After ablation,the number of premature ventricular contractions was decreased from 28 617±4 288 beats/day before ablation to 0～2 beats/day,and patients' symptoms were almost wholly disappeared.During an average follow up of 12 months,premature ventricular contractions were less than 5 beats/day. Conclusion:Radiofrequency ablation may be an alternative method to treat severely symptomatic but drug refractory and frequent premature ventricular contractions in patients without organic heart disease.
