Abstract:
Presentation of visual and acoustic stimuli at a rate of 2-30 Hz modulated variability of the heart rhythm in volunteers. Potentation of vagal influences and a decrease in the contribution of ergotropic systems to the regulation of the heart rate were noted after 10 sessions of audiovisual stimulation. These changes were accompanied by a pronounced decrease of individual and reactive anxiety.
