title: [Left ventricular segmental function in ischemic heart disease studied by ultrasonic methods].
abstract: 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.
