EFFECTS OF ANTIORTHOSTATIC HYPOKINESIA ONTHE SEQUENCE OF THE MYOCARDIAL DEPOLARIZATION AND REPOLARIZATION OF VENTRICLES AND HEMODYNAMIC INDICES OF THE HEART IN DOG
Electrophysiological properties and hemodynamics of heart were studied in 12 adult anaesthetized dogs in conditions of antiorthostatic hypokinesia. Differently directed changes in electrophysiological properties of layers and myocarium areas are revealed. Dependence of the sequence of repolarization from the sequence of activation of the ventricular myocardium is established. It is assumed that simplification of functions of the heart system is in the basis of the mechanisms participating in formation of physiological reactions under ANOH.
