目的探讨二尖瓣环收缩期峰值速度及收缩期位移评价扩张型心肌病患者左室收缩功能的价值。
Objective To probe the value of mitral annulus peak systolic flow velocity and systolic displacement in evaluating left ventricular systolic function of dilated cardiomyopathy patients.
纵向位移是测量收缩期心肌运动幅度，显现为心肌节段的速度-时间积分。
Longitudinal displacement measures myocardial motion amplitudes in systole and visualizes the segmental velocity - time integrals.
