Features of Cardiac Biopotentials in Patients with Acute Myocardial Infarction

I.Ye. Belaia


The paper describes the features of the changes in cardiac biopotentials at acute extensive myocardial infarction of the anterior left ventricular wall, which are vectorcardiographically characterized by a shift in QRS loops to the right, back and down, a decrease in the total area of QRS loops by all projections, local intraventricular blockade, the appearance of ST damage vector (upward and right), violation in the processes of late repolarization in the form of disorder of spatial orientation and phase values of T loops. In this, vector analysis has allowed not only to confirm the presence of myocardial necrosis, but also to clarify the transmurality of its damage in addition to electrocardiography. Besides, during vectorcardiography, there has been detected a compensatory hemodynamic overload of the compartments of the heart outside the ischemic myocardium.
