主动电极右室间隔起搏应用研究

目的 研究主动固定螺旋电极在右室流出道间隔部起搏中的应用.方法 将68例需要植入永久性心脏起搏器患者随即分成2组,应用主动螺旋电极行右室流出道间隔起搏简称主动电极组.应用被动电极植入心尖部起搏简称被动电极组.记录两组数中及术后的各项参数并进行比较.结果 两组均顺利完成手术,未出现严重并发症.主动电极组植入即刻起搏阈值比被动电极组要偏高,无显著差异.主动电极起搏QRS波时限明显短于被动电极组,有显著差异.两组感知阈值无明显差异.随访1个月,两组起搏阈值,阻抗,感知无明显差异.结论 主动固定螺旋电极在右室流出道间隔部起搏是稳定,安全,可靠的.

The active electrode right ventricular septal pacing applied research

Objective To study the active fixed helical electrode in the right ventricular outflow tract septal pacing in the application.Methods 68 patients required implantation of permanent cardiac pacemaker patients were then divided into two groups,the application of spiral electrode line right ventricular outflow tract septal pacing referred to as the active electrode group.The application of passive apical pacing electrodes were implanted referred to as the passive electrode group.Record two sets of numbers during and after the various parameters and compare them.Results Both groups were successful completion of the surgery,no serious complications.Active electrode group implanted in the immediate pacing threshold is higher than the passive electrode group,no significant difference.The active electrode pacing QRS wave limit is significantly shorter than the passive electrode group,a significant difference.The two groups perception threshold no significant difference.Follow-up one month,no significant difference in the two pacing threshold,impedance,and perception.Conclusion The active fixed spiral electrode in the right ventricular outflow tract septal pacing is stable,safe and reliable.
