title: [Myocardial contractility and relaxation in idiopathic hypertrophic subaortic stenosis].
abstract: The results of computer analysis of echocardiograms of 31 patients with idiopathic hypertrophic subaortic stenosis, patients with stenosis of the aortic orifice, and healthy individuals are discussed. An investigation was made of the local contraction and relaxation of the myocardium of the interventricular septum and posterior wall of the left ventricle, as well as the peculiarities of the total left-ventricular pumping function in patients with idiopathic hypertrophic subaortic stenosis and in those with stenosis of the aortic orifice. The specific features of left-ventricular blood filling and contraction and relaxation of the myocardium of the interventricular septum and posterior wall of the left ventricle in patients with idiopathic hypertrophic subaortic stenosis were determined.
