The pattern and nature of autonomic nervous system responses largely depend on the type of emotion. The study was aimed at defining shifts in the autonomic nervous system that accompany the emotional activation under the influence of emotionally accented TV news. Results indicated that a heart rate decelerated in a few minutes after the watching neutral video set. At the same time, throughout the viewing of the video, the activity of the parasympathetic system and the stress index decreased. Negatively accented TV news caused more complex changes. For men, the significant changes in heart rate were recorded only during the first TV news items. On the other hand, negative TV news stories elicited the most significant changes in parasympathetic system and stress index – these changes occurred in the middle of exposure to negative TV news set. The impact was stronger and more complicated for women and consisted of decreasing heart rate while watching TV news stories and accelerating heartbeats in the pause between them. A significant decrease in the parasympathetic system activity occurred after watching negative TV news. Regarding all the parameters, negative TV news stories exerted more significant influence on the psycho-physiological condition of the volunteers than neutral TV stories. Our study revealed the short-term media effects of negative and neutral TV news on the activation patterns of the autonomic nervous system. The short-term reactions of the individual to the mass media are those bricks that underlie a large-scale picture of the media impact on a mass audience. The fact of the existence of short-term media effects gives the base for a further research on the cumulative nature of TV news content’s impact on people, including the longitudinal perspective of media effects.

Abstract Background: Frequent cessations of respiration can greatly increase the prevalence rate of arrhythmia. It has been confirmed that cardiac activity is regulated by autonomic nervous system (ANS). And heart rate variability (HRV) is widely used as a method to evaluate the function of ANS. Therefore, we analyzed whether apnea can affect the balance and normal function of ANS using short-term HRV indices. Methods: Forty-five healthy subjects were asked to breathe normally and hold their breathing to simulate 10 times apnea. Thirty-six patients from the dataset of a sleep laboratory for the diagnosis of sleep disorders with 10 times apnea were included in analysis. We calculated short-term HRV indices of subjects in normal respiratory and apneic states, respectively. Results: Compared with normal respiratory state, respiration cease would lead to the values of the mean-RR, nLF, LF/HF, and α1 were significantly increase whereas the values of rMSSD and nHF were significantly decrease. Conclusions: Cessations of respiration would lead to an imbalance in function of ANS, as well as an increase in fractal characteristics of the heart. These changes in physiological state are likely to induce and cause the occurrence of arrhythmia, which is regulated by ANS.

Emotional Strain

To determine the features of the cardiovascular system functional state in students using some indicators of heart rate variability under emotional strain. The research involved 67 male students with an average level of daily motor activity. The age range corresponded to 18 - 23 years. All the examined in the personal history had no deviations in health status and were considered to belong to the main medical group. The tonic activity of the autonomic nervous system in the normal condition was determined using the rhythmocardiographic method on the “Varicard 2.51” hardware-software complex according to the indicators of heart rate variability mathematical analysis. Cardio intervals were recorded in the normal condition and under conditions of emotional stress (the examination session was a model of stress). The analysis of heart rate variability was carried out on the basis of the statistical analysis indicators evaluation - SDNN, pNN50 and variational pulsometry - Mo, AMo, MxDMn, IN. Depending on the initial tonicity of the autonomic nervous system, all examined students were divided into groups: vagotonics, normotonics and sympathotonics. Among the determined values, the examination stress had the greatest impact on the stress index and the share of neighboring RR intervals, which differ by more than 50 ms. If the stress index significantly increased in students with vago- and normotonia, the proportion of neighboring RR intervals, differing by more than 50 ms, decreased in all the studied groups Taking an exam led to psycho-emotional stress of the body. It caused autonomic provision restructuring of cardiac activity due to an increase in the sympathetic effect. The results of the research may be of interest to all participants of the educational process.

Objective. Frequent cessations of respiration can greatly increase the prevalence rate of arrhythmia. It has been confirmed that cardiac modulation is regulated by the autonomic nervous system (ANS). And heart rate variability (HRV) is widely used as a method to evaluate the function of the ANS. Therefore, we analyzed whether apnea can affect the balance and normal function of the ANS using short-term HRV indices. Methods. Forty-five healthy subjects were asked to breathe normally and hold their breathing to simulate 10 times apnea. Thirty-six patients from the dataset of a sleep laboratory for the diagnosis of sleep disorders with 10 times apnea were included in analysis. We calculated short-term HRV indices of subjects in normal respiratory and apneic states, respectively. Results. Compared with the normal respiratory state, respiration cease would lead to the values of Mean-RR, nLF, LF/HF, and α1 which significantly increased, whereas the values of rMSSD and nHF significantly decreased. Conclusions. Cessations of respiration would lead to an imbalance in the function of the ANS, as well as an increase in fractal characteristics of the heart. These changes in the physiological state are likely to induce and cause the occurrence of arrhythmia, which is regulated by the ANS.

Introdução: Existem poucos estudos que evidenciam a manipulação vertebral relacionada à modulação autonômica cardíaca. Objetivo: Revisar a literatura sobre os efeitos da manipulação vertebral sobre a modulação autonômica cardíaca. Métodos: Foi realizada uma busca bibliográfica nas bases de dados da saúde Medline, Pubmed e Cinahl, no período correspondido entre setembro e novembro de 2014. Foram utilizados os descritores em inglês Spinal Manipulation, Cardiac Autonomic Modulation, Autonomic Nervous System, Heart Rate Variability, além de associações entre eles. Resultados: Foram encontrados 190 artigos, sendo excluídos 39 por serem repetidos, restando 151. Destes, 124 não se encaixaram nos critérios de inclusão e após leitura crítica e análise dos materiais foram selecionados 7 artigos. Grande parte dos estudos revelou que a manipulação da coluna, independente do segmento, demonstra alterações autonômicas, tanto em nível simpático quanto parassimpático. Conclusão: Existem diferentes metodologias para avaliação da modulação autonômica cardíaca, sendo a Variabilidade da Frequência cardíaca através do eletrocardiograma a mais utilizada. A manipulação vertebral exerceu influência, na maioria dos artigos, sobre a modulação autonômica cardíaca.Palavras-chave: manipulação da coluna, sistema nervoso autônomo, variabilidade da frequência cardíaca.
