Data are presented on the application of ultrasonic sectoral scanning and B-scanning for the evaluation of the segmental function of the left ventricle in normal persons and in the patients with ischemic heart disease. In the normals the apical and low basal segments play the main part in the blood ejection from the ventricle, while in ischemic heart disease contractility disorders corresponding to the ventricle area affected with sclerosis are revealed. The method recommended permits one to assess not only qualitatively but also quantitatively the extent of segmental pathology. The marked symptoms of cardiac insufficiency and the extent of the ventricle affection are compared. It has been shown that the affection of more than 26% of the ventricular perimeter leads to the development of the symptoms of cardiac insufficiency.
本文介绍了超声扇形扫描和B型扫描在评估正常人和缺血性心脏病患者左心室节段功能中的应用。在正常人中，心尖段和心底下段在心室射血中起主要作用，而在缺血性心脏病中，可发现与硬化受累心室区域相对应的收缩功能障碍。推荐的方法不仅可以定性，还可以定量评估节段性病变的程度。对明显的心功能不全症状和心室受累程度进行了比较。结果表明，心室周长超过26% 受累会导致心功能不全症状的出现。
