摘要 目的探讨接受单腔起搏(VVI)和双腔起搏(DDD)模式的心脏起搏器长期治疗的患者心室累积起搏百分数与血浆N末端B型利钠肽原(NT-proBNP)水平。方法测定59例长期人工心脏起搏患者心室累积起搏百分数与血浆NT-proBNP水平,后者以10为基数的对数(lg)转化后行统计分析,比较不同起搏模式下右心室累积起搏百分数与血浆NT-proBNP水平的异同。结果 VVI组心室累积起搏百分数(83.61±20.50)%,高于DDD组的(45.93±34.62)%,差异有统计学意义;VVI组较DDD组患者血浆NT-proBNP水平高,其lgNT-proBNP分别为(3.24±0.54)pg/ml和(2.52±0.62)pg/ml,差异有统计学意义。结论接受VVI长期治疗的患者可能会产生起搏依赖性的心功能损害,增加心力衰竭、心房颤动等的发生;DDD起搏可以通过调整房室间期和模式转换减少右心室累积起搏百分数,对心功能损害比VVI起搏少。
