The assessment of reactions of polygraphic parameters at HRV-biofeedback training in adolescents with different variants of cardiac autonomic nervous system tone

Abstract

There is examine a character of change of brain bioelectric activity and polygraphs indicators at sessions of biofeedback by heart rhythm variability parameters (HRV-biofeedback) in 15-17 years adolescents who have different variants of cardiac autonomic nervous system tone. It is taped, that adolescents with cardiac balanced tone have more intensive optimization of functional brain activity in comparison with adolescents who have cardiac sympathetic tone - increase on alpha-activity and theta-activity depression in electroencephalogram structure. There were optimization of neurodynamic processes and most expressed stabilization of the hemodynamics indicators in adolescents with cardiac sympathetic tone after HRVbiofeedback training.
