title: [Combined noninvasive method of studying cardiac contractile function].
abstract: The method is based on a record of the polycardiogram, the first derived left-ventricular cardiogram (delta LVCG)--the rate apexcardiogram, the pressure phlebogram, and the tetrapolar rheogram and measurement of arterial pressure by an objective method. Logarithmic and linear nomograms were constructed and regression equations were deduced, which made it possible to calculate the pressure of ventricle filling and the pressure in the pulmonary artery by a bloodless method. The possibility of noninvasive determination of the ventricular pumping function and myocardial contractility is demonstrated.
