目的:评价导管射频消融治疗顽固性特发性右心室室性早搏近期及远期疗效。方法:症状严重、药物治疗疗效欠佳的顽固性特发性右心室室性早搏患者57例给予导管射频消融治疗,比较治疗前、后症状改善情况并进行远期随访。结果:导管射频消融治疗成功率96.5%,术后3d复查动态心电图提示室性早搏明显减少(P<0.01);术后1个月内复发2例,再次行导管射频消融治疗成功。室性早搏较术前明显减少(P<0.01),随访期间心悸等症状消失,无并发症发生。结论:导管射频消融术对治疗顽固性特发性右心室室性早搏近、远期效果良好。
OBJECTIVE: To evaluate the short-term and long-term effects of catheter ablation for refractory idiopathic right ventricular premature ventricular contractions. Methods: Fifty-seven patients with refractory idiopathic right ventricular premature ventricular failure who had severe symptoms and poor response to medical therapy were given radiofrequency catheter ablation. The symptoms before and after treatment were compared and the long-term follow-up was performed. Results: The success rate of radiofrequency catheter ablation was 96.5%. The dynamic electrocardiogram after 3 days of reoperation showed that the premature ventricular contractions were significantly reduced (P <0.01). Two cases recurred within one month after operation. The catheter radiofrequency ablation was successful again. Premature ventricular contractions were significantly reduced (P <0.01), during follow-up disappeared symptoms such as palpitations, no complications. Conclusion: Catheter radiofrequency ablation is effective in the treatment of refractory idiopathic right ventricular premature ventricular contractions.
