主动固定电极在右室流出道间隔部起搏的

目的探讨临床应用主动固定电极在右室流出道间隔部起搏的可行性及安全性。方法收集心脏起搏适应证患者118例。其中病态窦房结综合征40例,房室传导阻滞78例。所有患者均采用心室主动固定电极在右室流出道室间隔部起搏。结果118例患者均顺利完成手术,在右室流出道间隔部电极定位成功率为98.3%,起搏参数达到起搏标准,其中出现术中电极穿孔1例,术后电极脱位2例,脱位率1.7%。结论临床应用主动固定电极行右室流出道间隔部起搏安全可行。

Clinical application of active fixation electrode for right ventricular outflow tract septum pacing

Objective To evaluate the feasibility and safety of the clinical application of active fixation electrode in right ventricular outflow tract septum pacing. Methods One hundred and eighteen patients with indication of pacing were studied. Among whom,40 had sino-atria node syndrome and 78 atrio-ventricular block. All patients were undertaken an active fixation electrode positioned on right ventricular outflow tract septum for pacing. Results All 118 cases passed successfully through the procedure,with success rate of 98.3% in localization of the electrode at the right ventricular outflow tract septum accompanied by reaching the standardized pace parameters. The adverse incidences included 1 case of electrode perforation during the procedure,2 cases of dislocation afterwords(1.7%). Conclusions The clinical application of active fixation electrode for right ventricular outflow tract septum pacing is feasible and safety.
