The problems of studying the contractile function of the myocardium were investigated in patients with acquired heart diseases and varying stages of circulation insufficiency. Echocardiography was used to examine 92 patients, aged 17 to 38 years. The results of the examination permitted to obtain a clear understanding of the degree of changes in the myocardium contractile function. The most valuable parameters of echocardiogrammes which permit to record the early signs of cardiac insufficiency include the myocardium excursions rate, the ejection fraction, the contraction rate of the circular fibers of the myocardium, the percentage of shortening the anterior-posterior dimensions of the left ventricle.
对患有后天性心脏病且处于不同循环功能不全阶段的患者，研究了心肌收缩功能的相关问题。采用超声心动图对92例年龄在17至38岁的患者进行了检查。检查结果有助于清楚了解心肌收缩功能的变化程度。超声心动图中最有价值的参数，可用于记录心脏功能不全的早期迹象，包括心肌运动速率、射血分数、心肌环形纤维收缩速率、左心室前后径缩短百分比。
