[Clinical importance of studying intracardiac hemodynamics by recording local precardiac rheograms].

A high-frequency rheograph equipped with ceramic electrodes was used for recording local rheograms of the heart. The ventricular curves were recorded at points corresponding to the projections of the ventricles and the vascular curves, at the projection of the vessels. The parameters characterizing the condition of intracardiac hemodynamics in 40 healthy persons and in 50 patients with mitral valvular disease were determined. Changes were demonstrated which may be valuable in diagnosis and differential diagnosis of heart diseases.
