Abstract

The aim of this study was to determine the amplitude-frequency characteristics of the electroencephalogram (EEG) and heart rate variability (HRV) in humans, depending on the initial serum TNF-α level at a single session of heart rate variability biofeedback (HRV BF) due to increase the total power of the HRV spectrum. Among hypertensive individuals (blood pressure 140-160/80-100 mm Hg) subgroups with an optimal serum TNF-α level (below than 75 quartile - 84,4 pg/ml) and with a high serum TNF-α level (more than 84,4 pg/ml) were selected. In individuals with an optimal serum level of TNF-α, an increase in the total HRV spectral power, a decrease in the stress index, systolic blood pressure and a decrease in the EEG power in the theta range in the frontal brain regions after HRV BF session were identified. In individuals with a high serum TNF-α level the effectiveness of HRV BF was minimal against the background of continuing sympathicotonia and high theta EEG-activity.
