NEW POSSIBILITIES OF ECHOCARDIOGRAPHIC METHOD IN EVALUATION OF CYCLE ANALYSIS OF CARDIAC MECHANICS IN CARDIOGRAPHIC PATIENTS

Abstract

The article provides analysis of results of patient therapy under effect of levosimendan based on algorithm of evaluation of myocardium function on the basis of echocardiographic data. The results were evaluated on hemodynamic indicators – ejection fraction, pressure in the pulmonary artery, stroke output and myocardium contraction speed (dVol/dt), that were plotted in the automatic regime as a chart “Flow – Volume”. Vectors of the contraction speed characterize asynchronous behavior of the myocardium taking into account cardiomechanics in the form of cycle analysis of the cardiac mechanics. Effectiveness of levosimendan effect in cardiosurgical patients with the initially low ejection fraction of the left ventricle was proved.
