【摘要】 目的 :本研究旨在用一种新的超声心动图技术 -组织追踪法定量测量正常人群左室各个部位心尖方向运动及比较中国和德国人群的差异。方法 :我们研究 47例左室功能正常 ,无明显器质性疾病的中德人群 ,在心尖四腔心、三腔心和二腔心切面 ,用组织追踪法超声心动图测量收缩期前间隔、后间隔、前壁、后壁、下壁、侧壁向心尖方向的运动位移。结果 :在 47例试验者中 ,组织追踪法可以定量测量正常人群左室各个部位心尖方向运动位移 ,2 2例中国人和 2 5例德国人相应运动位移有明显差异 ,德国人的运动位移高于中国人 (P<0 .0 5 )。结论 :组织追踪法是一种可以简单的、快速的定量评价左心室纵向运动的方法 ,德国人的左心室纵向运动位移高于中国人更多还原

【Abstract】 Objective:The purpose of the study was to qualitatively measure the longitudinal displacement of the segmental movements of normal subjects’ left ventricles and find the difference between Chinese and Germans using tissue tracking technology.Methods:We studied forty seven normal subjects, including 22 Chinese and 25 Germans From the apical four chamber,three chamber and two chamber views, we measured the longitudinal displacements of six sites (PIVS,LAT,POST,AIVS,ANT,INF)by tissue tracking.Results:Tissue tracking could successfully measure the longitudinal displacement of the left ventricular movements of all subjects The longitudinal displacement of Germans’ left ventricular segmental movements was higher than that of Chinese( P <0 05).Conclusions:Tissue tracking is a simple, quick, noninvasive tool to qualitatively measure the longitudinal displacement of the ventricular segmental movements The longitudinal displacement of Germans’ ventricular movements is higher than that of Chinese.更多还原
