Repolarization of Heart Ventricles in Dogs during Recovery after Antiorthostatic Hypokinesia

摘要

Repolarization properties of ventricular myocardium were studied in anesthetized adult dogs of both sexes subjected to antiorthostatic hypokinesia (head-down tilt at 45A degrees and 60A degrees to the horizontal) and during recovery period (horizontal position for 15 min). The time of repolarization of ventricular myocardium during recovery surpassed the initial value, which represents an adaptive response of the heart to antiorthostasis.
