摘要

目的 :观察导管射频消融治疗右室流出道频发室性早搏（简称室早）的疗效及安全性。方法 :选择右室流出道频发室早患者 32例

随机分为常规标测组（16例）和冠状窦电极标测组（16例）

按常规方法进行射频消融

平均随访 2 2± 14月

观察射频消融的即刻和远期成功率及安全性和临床症状改善情况

并比较常规标测组与冠状窦电极标测组标测时间。结果 :①射频消融即刻和远期成功率分别为 10 0 %、93.8%

无 1例发生并发症 ;成功术后

由室早引起的症状消失。②冠状窦电极标测组标测时间明显少于常规标测组。结论 :右室流出道频发室早射频消融治疗成功率和安全性高 ;灵活应用常规导管引导标测可明显减少标测时间

亦即明显减少X射线的辐射能量。

Abstract

Objective:To investigate effects and reliability of catheter radiofrequency ablation of frequent ventricular premature beats(VPBs) originating from the right ventricular outflow tract(RVOT).Methods:32 patients with frequent VPBs originating from RVOT were randomly divided into conventional mapping group(16 patients) and coronary sinus electrode mapping group(16 patients).They were ablated with conventional metheds.During follow-up 22±14 months

radiofrequency ablation short-term successful rate and long-term successful rate

reliability

and the clinical symptoms were recorded.Mapping duration was compared between conventional mapping group and coronary sinus electrode mapping group.Results:(1)Radiofrequency ablation short-term successful and long-term successful rate were 100%

93.8% respectively.No complications occurred.The clinical symptoms caused by VPBs disappeared after successful ablation.(2)Mapping duration of coronary sinus electrode mapping group was shorter than that of conventional mapping group.Conclusion:Successful rate and reliability of radiofrequency ablation of VPBs originating from RVOT were higher.Mapping duration was decreased by smart application of conventional catheter

in other words

X-ray radiation energy was decreased.
