1、医学影像学杂志2009年第19卷第10期JMedImagingVol.19No.102009实时三维超声心动图评价高血压左室肥厚患者左室节段收缩功能1122刘翠红,赵可辉,艾阳平,巩德伟(1.山东中医药大学第二附属医院特检科山东济南250001;2.山东中医药大学山东济南250014)【摘要】目的:应用实时三维超声心动图技术评价高血压性心脏病患者左心室壁节段收缩功能。方法:分别应用实时三维超声心动图测量20例健康者、20例高血压左室肥厚患者的左室壁17节段节段每搏量(rSV)、节段射血分数(rEF)、节段射血率
2、(rPER)。结果:40例检测者均获得了具有清晰内膜边界的实时三维图像和17节段容积-时间曲线;两组间17节段rSV、rEF、rPER测量值间差异有统计学意义(P<0.05)。结论:高血压左室肥厚患者与正常人左室壁节段收缩功能存在差异,实时三维超声心动图是一种可行的、准确定量评价左室壁节段收缩功能的新技术。【关键词】超声心动描记术;实时三维;左心室功能;心肌收缩中图分类号:R542.2;R445.1文献标识码:A文章编号:1006-9011(2009)10-1277-04Studyonleftventricul
