SYSTEM ANALYSIS INDICATORS THE ALPHA RHYTHM OF THE BRAIN AND HEMODYNAMIC IN PATIENTS IN PATIENTS WITH ARTERIAL HYPERTENSION
The analysis of the relationships of amplitude-frequency indices of the alpha – rhythm of the brain in patients with arterial hypertension (AH) and healthy individuals. Examined 65 patients with AH degree 2 and 35 healthys individuals. All conducted EEG study, the daily recording of blood pressure, electrocardiogram (ECG) and electroencephalography (EEG). The results were evaluated by multiple regression, correlation and factor analysis in the program package «Statistica v. 10.1» StatSoft. Solved a series of multiple regression equations that showed the dependence of absolute and relative values of hemodynamic parameters from the index and the amplitude-frequency characteristics of the alpha – rhythm. Found that in hypertensive patients the decline of the index, amplitude and power of the alpha – rhythm to change the relationship of the alpha – rhythm between the lobes and hemispheres of the brain, correlated with hemodynamic parameters and heart rate.
