Reactivity of the vegetative nervous system influenced by non-verbal information

Aim. The article deals with establishing the HRV indicators influenced by non-verbal information. Materials and methods. Vegetative nervous system reactions have been estimated under the influence of non-verbal information as a response to the emotional state of the passive repeaters. The functional status of the repeaters was influenced by an emotional video. A recipient was in an isolated room surrounded by the group of the passive repeaters and was not subjected to a direct influence of the emotional video. The assessment of the vegetative responses in repeaters has been performed using tone- and pulsometry, in recipients - using the mathematical and time-domain analysis of a cardiorhythmogram. ECG recording was synchronized with video demonstration and divided into 9 conditional stages, each of 100 cardiocycles. The reliability of differences has been assessed with the Wilcoxon non-parametric criterion. Results. The intensity of vegetative nervous system reactions in both groups has been registered during the stages preceded by a video demonstration. In recipients, the high frequency of the significant changes in RRNN, RMSSD, pNN50, HR, M, Mo, AMo, VRI proves body sensitivity to non-verbal information. The low variability of certain indicators such as VR, SDNN, AMo, VB, and SI allows us to establish their specificity. Conclusion. The presence and intensity of a vegetative reaction in the recipients is determined by the modality of the emotion formed in a passive repeater. This effect can be possibly considered as an emotional resonance in the recipient induced by asthenic emotions and the feeling of compassion and regret in the repeater as a response to an emotional video.
