| 摘 要： | 目的探讨组织多普勒成像（TDI）检测二尖瓣环运动对左心室收缩功能的评价作用。方法以TDI技术检测心尖四腔切面二尖瓣前叶瓣环的收缩期运动峰值速度（Sm）,以M型超声左心室长轴切面测量射血分数（EF）,计算Sm与EF的相关性。结果Sm与EF呈正相关（P〈0.01）。结论TDI技术测量Sm评价左心室收缩功能较EF更敏感、更快捷。

| Abstract: | Objective To investigate the evaluative role of tissue Doppler imaging(TDI) on the left ventricular systolic function by detection of the mitral annular movement.Methods The systolic movement(Sm) peak velocity of mitral annular in the apical four-chamber view was detected by TDI,and the ejection fraction(EF) in the left ventricular long axis view were measured by M-mode echocardiography.The correlation between Sm and EF was analyzed.Results Sm was positively correlated with EF(P<0.01).Conclusion Sm detectio... |
