Electrophysiological feature of the preclinical stage of the initial manifestations of insufficiency brain blood circulation of decreed persons in Republic of Kareliya
Abstract
To discover legitimate diagnostics methods of precerebral thrombosis diseases some actions were made: we learned physiological characteristics (electrocardiogram, tetrapolar rheography, rheoencephalography, ultrasonic dopplerography of cervical and cerebral arteries, transcranial dopplerography, electroencephalography of preclinical stage of the initial manifestations of insufficiency brain blood circulation, during the dispensary doctor's examination of decreed contingents in Republic of Karelia (workgroup - patient- military personnel, n = 108; control group - people in good health, n = 35). People with preclinical stage of the initial manifestations of insufficiency brain blood circulation were discovered disturbance of phase of repolarization and heart rhythm; normal hemodynamics type, double-sided high-to-low speed transition of bloodstream through the front cerebral and vertebral arteries, diffusive hypertension of head main artery with the loss of their elasticity in carotid pools and pulse blood filling in the pool of the left vertebral artery; diffusive hypertension of arterioles and brain veins; desynchronized and disorganized types of electroencephalography (concernment level < 0,05). We discovered the specificity of the electrophysiological indexes depending on principal etiological reasons of preclinical stage of the initial manifestations of insufficiency brain blood circulation (somatic vegetative dysfunction, osteologist of spine neckerchief), arterial hypertensia, cerebral atherosclerosis, sclerosis, obesity, depressive frustration). Doctors offered diagnostic toolbox for screening-diagnostics of preclinical stage of the initial manifestations of insufficiency brain blood circulation of military men: electrocardiogram, tetrapolar rheography by Kubichec (systolic index, specific peripheral resistance, systolic and diastolic arterial pressure), rheoencephalography (indexes: reographical, dikrotic, diastolic, Q_x, α, α1, α2) - for all etiological subgroups. Electroencephalography, ultrasonic dopplerography of cervical and cerebral arteries and transcranial dopplerography is reasonable to do because of the development of preclinical stage of the initial manifestations of insufficiency brain blood circulation at the background of osteologist of spine neckerchief, arterial hypertensia and cerebral atherosclerosis.
