摘要 目的:探讨在心力衰竭病人中跨室壁复极离散度与射血分数及心率变异性之间的相关性。方法:对2005年1月至2007年2月之间住本院心内科的心力衰竭患者的跨室壁复极离散度、射血分数及心率变异性分别进行测量,并计算其相关性。结果:跨室壁复极离散度与射血分数之间存在显著负相关(r=-0.674,P<0.01),与心率变异性时域功率多个指标呈负相关[与总体标准差(SDNN)之间存在负相关(r=-0.475,P=0.019),与均值标准差(SDANN)之间存在较为显著负相关(r=-0.405,P=0.05),与标准差的增均值(SDNNIndex)之间存在负相关(r=-0.499,P=0.013)]。结论:心力衰竭病人中跨室壁复极离散度增大,则射血分数下降,心率变异性下降,可能导致患者猝死风险增大。
