The Functional State of the Cerebral Circulation Depending on the Localization of Transition Area in Chest Lead of ECG at Orthostasis

Abstract

The article is devoted to the study of the functional state of the cerebral circulation at orthostasis in persons of young age with different localization of transition area in chest lead of ECG. Four groups of respondents, depending on the localization of transition area in chest lead of ECG: group 1 - V1-2; group 2 - V3; group 3 - V4-5; 4 group - undetermined localization. Registration of electrocardiograms and parameters of cerebral hemodynamic was performed using program complex «Valenta». Urgent mechanisms of the cerebral circulation are due to a slight increase in pulse blood brain in significant reduction venous outflow from the region. The influence of the local electrophysiological position of the heart on the regulation of cerebral blood flow was established. Unfavorable reaction of cerebral circulation at orthostasis was observed in respondents with the horizontal location of the heart (V1-2) and undetermined localization of transition area in chest lead of ECG.
