The same mediators of the autonomic nervous system can be both triggers and modulators of internal organs activity, and heart autonomic regulation can be best estimated by studying heart rate variability (HRV). The objective of the present research is the estimation of both time and spectral HRV parameters in patients with non-rheumatic myocarditis depending on its clinical course. 58 patients (20 men and 38 women) aged 35,3  1,3 years were examined. 22 (37,9 %) patients have established acute myocarditis, and 36 (62,1 %) - postmyocardic cardiosclerosis (PMC). HRV parameters were estimated depending on the disease stage, and on presence of heart rhythm disturbances. Patients with acute myocarditis compared to those having PMC had decreased HRV parameters (SDNN, SDANN, SDNNi, pNN50, rMSSD) refl ecting vegetative imbalance, and ventricular ecthopic activity in patients with myocarditis is associated with the activation of both sympathetic and parasympathetic system, and these changed are more expressed in patients with high ventricular extrasystole gradation.

The Relationship

The research results showed that the vegetative tone of the nervous system in different phases of the menstrual cycle is different. In accordance with changes in heart rate (HRV) indicators, we can talk about the predominance of tone of either the sympathetic or parasympathetic department of the autonomic nervous system in each phase of the cycle, to distinguish subgroups of students by the distribution of the tone of the autonomic nervous system during the cycle. It was possible to isolate those HRV indicators that were changed most synchronously (rhythmogram, histogram, and scatterogram indices). The spectrogram indices are distinguished by the highest asynchrony of changes; therefore, it is not very convenient to analyze changes during a cycle. Autocorrelation indicators reflect the relationship and the predominance of one of the circuits of heart rhythm regulation (central or autonomous). Despite the fact that a certain dynamic of changes can be traced, significant differences were noted only for some indicators in each of the groups. HRV indicators in accordance with the standards given in the literature should be clarified.

The Relationship

Mechanisms of regulation of cardiac rhythm have many individual features, which are conditioned by age, sex, training of the organism, strength and nature of external influence, constitutional features of the organism. The purpose of the work is to determine the relationship between cardiointervalographic indices and parameters of the external structure of the body in highly skilled wrestlers of the mesomorphic somatotype. The study involved 24 wrestlers between the ages of 17 and 21 with a high level of sportsmanship and more than 3 years of experience. All of the wrestlers were of medium weight and engaged in free and Greco-Roman wrestling. We conducted a study of heart rate variability on the cardiac computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association (1996). The indices of vegetative homeostasis according to Bayevsky, variational heart rate, statistical and spectral cardiointervalographic indicators were determined. Anthropometry was performed according to the method of V.V. Bunak (1941), somatotypological study – by the calculated modification of the Heath-Carter method (1990), determination of the component composition of body weight by the method of Matejko (1992). In the package “STATISTICA 5.5” correlation analysis was performed using the nonparametric Spearman statistical method. It was found that in the wrestlers of the mesomorphic somatotype, the variations of the pulsometry had the highest number and strength of reliable correlations with constitutional parameters, most of which were inverse of the mean force. All statistical indicators of heart rate variability with indicators of the external structure of the body had only inverse significant correlations. The least significant correlations were found for spectral indices and parameters of vegetative homeostasis. According to the results of the correlation analysis in the wrestlers of the mesomorphic somatotype, we can assume that with the increase of total, longitudinal, circumferential, transverse body sizes and muscle and bone mass, the variability of the heart rhythm of the sympathetic department of the autonomic nervous system will be more pronounced.

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.

Cardiovascular Morbidity And Mortality

Heart rate variability (HRV) is highly influenced by the Autonomic Nervous System (ANS). Several illnesses have been associated with changes in the ANS, thus altering the pattern of HRV. However, the variability of the heart rhythm is originated within the Sinus Atrial Node (SAN) which has its own variability. Still, although both oscillators produce HRV, the influence of the SAN on HRV has not yet been exhaustively studied. On the other hand, the complications of diabetes mellitus (DM), for instance, nephropathy, retinopathy, and neuropathy, increase cardiovascular morbidity and mortality. Traditionally, these complications are diagnosed only when the patient is already suffering from the negative symptoms these complications implicate. Consequently, it is of paramount importance to develop new techniques for early diagnosis prior to any deterioration on healthy patients. HRV has been proved to be a valuable, noninvasive clinical evidence for evaluating diseases and even for describing aging and behavior. In this study, several ECGs were recorded and their RR and PP intervals were analyzed to detect the interpotential interval (ii) of the SAN. Additionally, HRV reduction was quantified to identify alterations in the nervous system within the nodal tissue via measuring the SD1/SD2 ratio in a Poincaré plot. With 15 years of DM development, the data showed an age-dependent increase in HRV due to the axon retraction of ANS neurons from its effectors. In addition, these alterations modify the heart rhythm-producing fatal arrhythmias. Therefore, it is possible to avoid the consequences of DM identifying alterations in SAN previous to its symptomatic appearance. This could be used as an early diagnosis indicator.
