THE HEART ELECTRIC FIELD OF MAN DURING VENTRICULAR REPOLARIZATION UNDER HYPOXIC INFLUENCE
The study of the electrical activity of the healthy young man's heart has been carried out during ventricular repolarization under short-term acute moderate normobaric hypoxia by the method of synchronous multichannel cardioelectrotopography from 64 unipolar leads on the thorax surface and by the method of electrocardiography from the second limb lead. During acute normoaric hypoxic influence the changes of repolarization of the heart ventricles have been revealed: the shortening of the corrected QT interval corresponded to a decrease of durations of J-Tpeak<sub>II </sub>and Tpeak-Tend<sub>n</sub> intervals, the severity of correlation changed with the influence duration; the time of achievement of maximum values by extrema of the heart electric field was earlier; the changes of temporal dynamic of the negative extremum were shown.
