Students who attend a medical HEE often face strain in their adaptation mechanisms when preparing for exams; it can create substantial preconditions for functional deregulation in body systems. The articles outlines some results obtained via examining heart rate variability (HRV) in students of the 2nd and the 3rd year attending the North Ossetia State Medical Academy who had different metabolic status in a period prior to exams. Our research goal was to assess the state of the vegetative nervous system and regulatory systems in students with different metabolic status (BMI< 25; BMI=25–29.99; BMI=30–34.99.) who had to face excess stress during preparation to exams. Heart rate intervals were registered during five minutes in an examined person being at rest. HRV parameters were analyzed in time and frequency domains. We revealed that medical students had elevated activity of the sympathetic section in their vegetative nervous system (VNS) during a period prior to exams; in particular, it was apparent for the regulation system of the vasomotor center (PLF = 48.4%). Students’ bodies had apparent strain in their regulatory systems (SI=177.5 a.u.). Total activity of the regulatory system was significantly elevated (TP=2,293 msec2) due to central regulation levels. As students’ BMI grew, there was a decrease in activity of the parasympathetic component in vegetative regulation and heart rate management became more centralized (IC=3.2–4.5 a.u.). Students with Class 3 obesity had the maximum spectrum power of the superlow component in heart rate variability (PVLF=29.3%). HRV parameters analysis allows estimating whether adaptation processes in students’ bodies are adequate during preparation to exams; it can be done in screening mode and provides an opportunity to perform timely prevention activities.

Оn the basis of the heart rate variability analysis in 41 patients during acute period of nontraumatic intracranial hemorrhages it was revealed that dynamics of the vegetative dysfunction rise was characterized by transition from reflex to humoral metabolic type of regulation. The reduction of reactivity of vegetative nervous system parasympathetic part during respiratory and active orthostatic test was noted. The method of evaluation of vegetative nervous system reactivity by means of heart rate variability analysis recorded before, during and after lumbar puncture with measure of cerebrospinal fluid pressure was worked out. It allows to evaluate the reactivity of suprasegmental centers (adequate, insufficient, exhaustion), raises accuracy of detection of adaptive organism resources with the detachment of the disease course variant and helps to reveal correlation of exertion extent of suprasegmental centers with hypertensive hydrocephalic syndrome.

Steopathic correction is one of the treatment methods, based on the individual and holistic approach to the recovery of human health. The analysis of the heart rate variability helps to evaluate the influence of osteopathic correction on the synergism and balance of the vegetative nervous system and permits to objectify the current changes of the vegetative status.

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.
