title: [Assessment of the functional status of the left and right ventricles in the intact and damaged heart during volume overload].
abstract: Changes in hemodynamics, reserve capacities of intact and damaged myocardium have been studied, with the left and right ventricular functions during mounting volume load assessed separately. It has been shown that exclusion of the part of left ventricular myocardium from contraction deteriorated considerably the pump and contractile function not only of the left but also of the right intact heart ventricle. Heart failure in volume overload manifests itself primarily in the right ventricle and depends on the functional heart reverse on the whole: in animals with partial injury of left ventricular myocardium heart failure developed in much lower volume loads than in intact animals. In circulation volume overload, left or right ventricular stroke work index to preload or filling pressure in the corresponding heart chamber ratio was most adequate and prognostically valuable for the detection of latent heart failure.
