目的:探讨射频消融治疗频发室性期前收缩的临床效果和安全性。方法:经常规体检、生化检查、X线胸片、心脏彩超、长程心电图等各种检查后,入选室性期前收缩患者98例,其中右心室流出道室性期前收缩82例,左心室流出道室性期前收缩10例,左心室流入道室性期前收缩6例,分别采用起搏或起搏与激动结合的方法进行标测消融,对临床效果和安全性进行总结。结果:手术成功有90例,好转有6例(再次手术成功5例,1例室性期前收缩较前减少),手术失败2例。术后随访6个月~7年,未发生任何手术并发症。结论:射频消融治疗室性期前收缩是一种安全、有效的方法,该技术可进一步推广。
Objective: To investigate the clinical effect and safety of radiofrequency catheter ablation in the treatment of frequent premature ventricular contractions. Methods: After routine examination, biochemical examination, chest X-ray, echocardiography, long-range electrocardiogram and other examinations, 98 cases of premature ventricular contractions were selected. Among them, 82 cases were ventricular premature contractions in right ventricular outflow tract, Outflow tract ventricular contraction in 10 cases, left ventricular premature ventricular contractions in 6 cases, respectively, by pacing or pacing and activation of the method of mapping ablation, the clinical efficacy and safety were summarized. Results: There were 90 cases of successful operation, 6 cases of improvement (5 cases of successful operation again, 1 case of premature ventricular contractions reduced), and 2 cases of failed operation. Follow-up 6 months to 7 years after surgery, no complications occurred. Conclusion: Radiofrequency ablation is a safe and effective method for the treatment of premature ventricular contractions. This technique can be further popularized.
