为探讨一种实用的定量评价室壁运动的方法,本文动态分析了冠心病34例、原发性心肌病6例和正常人25名右前斜30°左室造影影象,计算局部射血分数(EFR)和轴线缩短率(％⊿α)。结果证实:室壁运动障碍表现在射血早期,射血末期可无异常运动存在,EFR和％⊿α法对诊断冠心病具有针对性;％⊿α和EFR对运动异常的检出率与冠状动脉病变部位符
In order to explore a practical method for the quantitative assessment of ventricular wall motion, this article dynamic analysis of 34 cases of coronary heart disease, 6 cases of primary cardiomyopathy and 25 normal right anterior oblique 30 ° left ventricular imaging to calculate the local ejection fraction (EFR) and axial shortening (% ⊿α). The results showed that: the performance of wall motion disorders in the early ejection, the end of ejection can be abnormal exercise, EFR and% ⊿ α method for the diagnosis of coronary heart disease targeted;% ⊿ α and EFR detection of motor abnormalities and coronary Arterial lesion site symbol
