摘要(Abstract)：
目的比较主动固定临时起搏器与传统临时起搏器的安全性及有效性。方法分析2011年1月至2013年6月于北京大学人民医院行电极拔除术的起搏器依赖患者105例,其中2011年1月至2012年12月患者采用传统电生理导管的临时起搏方式,纳入传统临时起搏组,资料为回顾性分析;2013年1月至2013年6月使用主动固定临时起搏,纳入主动固定临时起搏组,资料为前瞻性分析。对比两组间的起搏感知参数、手术时间、并发症及随访2年内的感染复发率和死亡率。结果共纳入105例患者,其中传统临时起搏组70例,主动固定临时起搏组35例。主动固定临时起搏组的起搏阈值[(0.7±0.2)V比(1.0±0.3)V,P=0.035]及临时起搏并发症发生率(0比15.8%,P=0.009)低于传统临时起搏组,差异均有统计学意义。主动固定临时起搏组的临时起搏保留时间[2(2,7)d比2(2,3)d,P=0.032]大于传统临时起搏组,差异有统计学意义。两组患者X线曝光时间与无感染生存率比较,差异均无统计学意义(均P>0.05)。结论相对传统临时起搏,主动固定临时起搏可显著降低临时起搏相关的并发症,延长临时起搏保留时间,增加患者的舒适性,且不增加手术操作时间。
