摘　　要：由于右心室腔几何形状复杂,一直以来评价右心室功能都比较困难。组织多普勒成像技术为心功能的评价提供了新的、敏感的方法。该技术在传统的彩色多普勒技术基础上,通过改变多普勒滤波系统,去除心腔内血流产生的高速、低振幅的频移信号,保留心肌运动产生的低速、高振幅的频移信号,是一项无创、定量分析心室壁运动的新技术。目前,组织多普勒成像不仅能对心肌功能障碍的性质和程度做定量分析,还是更加复杂尖端的技术如心肌应变率检查的基础。右心室组织多普勒成像简单易行,重复性好,可提供有关右心室收缩和舒张功能的附加信息。本文就近年组织多普勒成像在右心室壁运动及心功能分析方面的研究进展作一综述。Evaluation of right ventricular function is considered as a challenging process due to the complex shape of the right ventricular chamber.Tissue Doppler imaging（TDI） is a technique offering a new and sensitive method to evaluate heart function.TDI is a new non-invasive and quantitative technique to analyze ventricular wall motion,which can remove frequency shift signal with high speed and low amplitude resulting from blood of heart and remain frequency shift signal with low speed and high amplitude by changing filtering system on the basis of traditional color Doppler.At present,TDI not only can analyze quantitatively the degree and character of myocardial dysfunction,but also is the basis for more complicated advanced technique such as the examination of myocardial strain rate.Right ventricular tissue Doppler imaging is a feasible,reproducible,and easily performed additional echocardiographic measure of right ventricular systolic and diastolic function.This article reviews the progress inTDI analysis of right ventricular wall motion and cardiac function.
