ВЗАИМОСВЯЗЬ МЕЖДУ ТРЕВОЖНОСТЬЮ И ВАРИАБЕЛЬНОСТЬЮ СЕРДЕЧНОГО РИТМА ПРИ КОРРЕКЦИИ ПСИХОЭМОЦИОНАЛЬНОГО НАПРЯЖЕНИЯ, "Российский физиологический журнал им. И.М. Сеченова"

Dynamic of heart rate variability was studied in 33 subjects (16 women and 17 men; 18—55 years) during testing of anxiety (according to Spielberger) before and after correction of psychoemotional stress by original method of psychoemotional stability (Nikolaev A. B., Sudakov S. K., 2017). After correction of emotional stress a significant decrease in state and trait anxiety was observed. During testing of anxiety before the correction a decrease the length of RR intervals, which indicated the dominance of the defensive component in the structure of intellectual activity, was recorded. The total spectral power and power of the VLF range increased after the correction. The high values of the total spectral power and power of the VLF range during testing indicate a greater manifestation of the orientation component in the composition of intellectual activity.
