title: [Electrical activity of the myocardium and hemodynamics in patients with myocardial infarct].
abstract: A total of 53 patients with myocardial infarction were examined on the 1st, 21st and 45th day of the disease. The electric activity of the myocardium was studied by the method of spatial quantitative vectorocardiography. An investigation into the basic hemodynamic indices was made by employing the dilution method (Evans blue) A correlation-statistical model was constructed to elicit the relationship between vectorocardiographic changes and hemodynamic indices. It was found that in cases of myocardial infarction with and without symptoms of circulatory insufficiency there exists between the electric activity of the ventricular myocardium and cardiac ejection a differently marked interrelation on the ground of which one can form a certain judgement as to the functional condition of the intact segments of the left and the myocardium of the right ventricle.
