| 摘 要： | 目的 探讨组织多普勒（DTI）Tei指数评价慢性肺心病患者右心室功能的临床价值。方法超声观察56例慢性肺心病患者（病例组）及40例正常人（对照组）常规超声指标，超声指标包括：右心室横径、右心室前壁厚度、肺动脉主干内径、根据三尖瓣反流估测肺动脉收缩压。超声心动图DTI条件下，于心尖四腔观获得右心室游离壁近三尖瓣瓣环位点组织多普勒频谱，测量舒张晚期Am波终止至下一舒张期Em波起始的间期（a）和收缩期Sm波的间期（b），通过（a-b）／b计算Tei指数。结果病例组较对照组指数明显延长（P〈0．01）。结论右心室Tei指数是反映右心整体功能的较敏感指标．DITTei指数可综合评价肺心病患者右心室整体收缩舒张功能。 |
