The article presents the results of the use of speleoclimatotherapy in recreational activities in children of primary school age. In the course of the study, we analyzed indicators of heart rate variability in children depending on the initial vegetative status. In vagotonics and normotonics, there was an increase in the activity of the sympathetic division of the autonomic nervous system, and in sympatotonics, there was a decrease in HRV parameters within the age norm, characteristic of increased activity of the sympathetic division of the autonomic nervous system. Such changes can occur when the adaptive reserves of the childs body increase. However, when using speleoclimatotherapy during recreational activities, it is necessary to take into account the initial level of vegetative activity of heart rate regulation in children.

The objective: to establish the features of fetus functional state definition in pregnant women with perinatal losses in history. Patients and methods. 89 pregnant women with perinatal losses in history were screened. The fetus functional status evaluation was based on cardiotocography and definition of fetal heart rate variability by cardiointervalography. Results. Received data showed the decrease of SDNN, RMSSD and pNN50 in pregnant women with perinatal losses in history, indicating the prevalence of parasympathetic effects on the fetal myocardium (p<0.05). Studies of mathematical time characteristics of fetal heart rate revealed a significant overweight of the metabolic-humoral regulatory circuit in women with normal pregnancy (p<0.05). Dynamic stress index evaluation indicates the centralization of heart rate regulation and significant intensity of the fetal compensatory mechanisms in pregnant women with perinatal losses in history. The cardiotocography revealed no difference between the fetal status in women of comparative groups (p>0.05). Conclusions. In pregnant women with perinatal losses in history owing to autonomic nervous system disregulation a significant intensity of fetal regulatory systems and the centralization of fetal cardiac rhythm control were observed. The cardiotocography and cardiointervalography data with revealed signs of excessive sympathetic activation can serve as preclinical signs of gestational pathology. Key words: perinatal losses, fetal functional state evaluation, cardiotocography, cardiointervalography, autonomic nervous system.

Aim: to study the bioelectric activity of the brain in relation to changes in the tone of the autonomic nervous system as assessed by heart rate variability (HRV) and evoked skin  sympathetic potentials (ESSP) in patients with migraine and epilepsy.Materials and methods. We studied patients with epileptic foci in the left (group 1) or right (group 2) hemisphere with migraine attacks followed by epileptic seizures. We used EEG recording  and EEG mapping programs and also determined HRV and ESSP.Results. We found that the subjects in group 1 had the normothymic and parasympathetic types  of heart rate control, and the subjects in group 2 tended toward the sympathetic type of heart rate  regulation. The spectral correlation EEG data indicated that the epileptiform activity in group  1 was more generalized than in group 2, which pointed to a more pronounced epileptogenesis in  group 1. In this group, all pain scores were higher than those in group 2. In group 2 though, depression, anxiety, and emotional disorders were more pronounced than in group 1.Conclusion. The findings can be explained by a closer connection between the right hemisphere and the limbic system. This, in our view, underlies the more pronounced changes in the tone of the  autonomic nervous system as assessed by the HRV and ESSP in patients with the right hemisphere epileptic activity and migraine attacks.

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.

BACKGROUND Heart rate variability (HRV), or the variation in the time interval between consecutive heartbeats, is a proven measure for assessing changes in autonomic activity. An increase in variability suggests an upregulation of the parasympathetic nervous system (PNS). Music was shown to have an effect on the limbic system, respiratory rate, and blood pressure. However, there have been relatively few empirical investigations on the effect of music on HRV compared to mean heart rate (HR). Also, the majority of studies have been experimental rather than interventional, reporting significant changes in HRV as a function of musical characteristics, such as tempo, genre, and valence. OBJECTIVE The aim of this pilot study is to evaluate the impact of short duration music listening on the autonomic nervous system response of healthy adults. METHODS Six participants (three males and three females) were tested to investigate the effect of listening to music on HR and HRV. Electrocardiographic (ECG) data was recorded at a sampling rate of 1000 Hz using an eMotion Faros 360 device produced by Bittium Biosignals. The data was collected while the participants listened to four pre-selected songs in a random order separated by a relaxation period of 5 minutes. Data was then cleaned and processed through Kubious HRV 2.0 software. Statistical analysis using Wilcoxon signed rank test was carried out for the time and frequency domains. RESULTS For all but one song that is shorter than 3 minutes (song 1), we observed a statistically significant increase in Standard Deviation of the RR intervals (SDRR) (song 1: P=.125, r=.333; song 2: P=.023, r=.575; song 3: P=.014, r=.635; song 4: P=.014, r=.635) and in the Low Frequency (LF) component of the cardiac spectrogram (song 1: P=.300, r=.151; song 2: P=.038, r=.514; song 3: P=.014, r=.635; song 4: P=.014, r=.635) with a large effect size r, indicating increased HRV. No significant change in mean HR was observed (song 1: P=.173 r=-.272; song 2: P=.058, r=-.454; song 3: P=.125, r=-.333; song 4: P=.232. r=-.212). CONCLUSIONS Listening to pre-selected songs of longer duration than 3 minutes 30 seconds is associated with significant increases in HRV measures, especially SDRR and LF. Music thus has the potential to overcome autonomic nervous system (ANS) dysregulation and thereby benefit health and wellbeing.
