射频消融希氏束旁旁道的回顾性分析

目的 对10名希氏（His）束旁旁道（Ap）致倾向型房室折返性心动过速（O-AVRT）患进行射频消融（RFCA）治疗，综合分析X线曝光时间、操作时间、术后复发率和严重并发症发生率等因素，指出，His束电极的准确放置、尽量避免大头电极导管重复使用、术丰富的射频消融手术经验：包括介入操作技术和靶点图的识别，是安全有效进行His束旁旁道RFCA治疗的关键。

Retrospective analysis of radiofrequency catheter ablation of His bundle accessory pathways

Objective Ten patients with His bundle accessory pathways (APs) induced O-AVRT treated by radiofrequency catheter ablation (RFCA) were analyzed retrospectively. The main reason for the failure about two cases was much used ablation-catheter, unskilfulness of the manipulation of catheter ablation and misguided recognition of local electrogram of Ap. After analyzing these factors, which were duration of fluoroscopy exposure, successful rate of operation, recurrent rate and serious complications, it was pointed out that correct position of His bundle catheter, using new large-tip catheter and a operator with rich experience were the key to ablated His bundle Aps successfully.
