Objective: Tei index is usually measured with pulsed wave Doppler (PWD). Our aim was to assess the degree of agreement between PWD and a method based on tissue Doppler imaging (TDI) and its clinic application.

• 研究目的:本研究应用组织多普勒技术成像的频谱方式来评价左室Tei指数,通过与脉冲频谱多普勒的方法对比,来探讨应用组织多普勒技术来计算左室Tei指数的可行性问题及其临床应用。
