Purpose: Conduct an analysis of cardiac rhythm variability in the cows of the Jersey breed with a different vegetative status.Materials and methods. Indicators of the electrocardiogram (ECG) and cardiac rhythm variability studied on cows of the Jersey breed (n = 103). For the analysis and removal of ECG, the animal studied used the program «Conan-4.5» in the system of frontal administrations according to the method of P. M. Roshchensky. Clinical research methods were carried out according to the methods of clinical inspection of animals B. V. Ears and included — inspection, palpation, percussion and auscultation of the heart area.Results. Among the entire studied array of animals, the largest amount was sympathyone — 50,5%, normotonics — 24,3%, hypersympathicotonics — 16,5%. The smallest amount — vagotonic — 8,7%. For the vagotonic, the respiratory modulation index was 8,16±0,02%, the index of the sympathetic system is 43±0,1%, and the index of slowly wave arrhythmia is 0,8±0,1%. This group of cows parasympathetic (software) prevails over the sympathetic department of the vegetative nervous system. For normotonics, the value of the respiratory modulation index was 4,14±0,03%, the index of the sympathetic system is 96±0,2%, and im is 2,5±0,2%. This group is characterized by an equilibrium state between sympathetic department and VNS. The ids for sympathicotonists amounted to 2,78±0,03%, the index of the sympathetic system is 195±0,2%, and im is 8,2±0,1%. At sympathicotonists, which are characterized by a predominance with VNS above software. The hyper smpathetical respiratory modulation index was 1,34±0,02%, ICAS — 588±0,1%, and im is 11,4±0,3%. In hypersympathicotonists, which are characterized by the predominance of the super-viper vehicle of the vegetative nervous system over parasympathetic.Conclusion. The separation of the entire array on the subgroups based on the vegetative status of animals was based on the indicators of the voltage index of regulatory systems. To confirm the correctness of the separation of the studied array of animals on the subgroup, statistical processing was carried out and a classification matrix was built. Also, to confirm the classification separation matrix, additional statistical processing of the material of the differences between the obtained groups in the square of the distance of the Mahalonobis D2 was carried out. In the course of further registration and mathematical analysis of the variability of the heart rate of cattle (cows of the Jersey breed) with the help of a modern complex electrophysiological laboratory «Conan-4.5» features of indexes of A. Ya. Kaplan were established.

The objective: studying of features of the psychoemotional and vegetative status at women with placental dysfunction at the previous pregnancy. Patients and methods. Complex clinical-laboratory examination of 89 women, from which was conducted: control group – 42 obstetrically and somatically healthy multipara, delivery through natural patrimonial ways; І group – 47 women with placental dysfunction at the previous pregnancy. Carried out a cardiointervalografia by means of a single-channel electrocardiograph and used a scale questionnaire of a condition of the pregnant woman. Results. It is established that regulation of cardiac rhythm at women at the previous pregnancy happens to placental dysfunction in the conditions of an autonomous contour which controls normal work of heart and vegetative nervous system. Further, there is an expressed strain of regulatory mechanisms that is shown by centralization of management of cardiac activity and sharp rising of activity of sympathetic nervous system. At the final stage influence of the central contour considerably decreases and patofunctionale vegetative equilibrium is again formed. Conclusions. The received results need to be considered when developing tactics of conducting pregnancy at these women. Key words: placental dysfunction, vegetative and psychological status.

Adaptive Reactions

According to modern data, the cardiovascular system is a kind of indicator of the organism's adaptive activity, and the structure of the heart rhythm carries information about the development of adaptive reactions in response to irritating factors of the external and internal environment.The aim of the study – to investigate the functional state of the autonomic nervous system in pregnant women who have harmful habits by evaluating and analyzing the parameters of heart rate variability in order to prevent complications of non-delivery of gestational process.Materials and Methods. The study involved 73 pregnant women, 53 of them were pregnant (the main group) who had malignant habits in history. Before studying adaptive reactions in pregnant women, a study of cardiac rhythm variability was performed in practically healthy non-pregnant women of reproductive age (25.3±2.2) years). The control group consisted of 20 pregnant women without any harmful habits. Determination of heart rate variability was performed on the basis of peripheral heart rate recording, which included measuring the sequence of RR intervals for 5 minutes, followed by mathematical analysis using the PlsMntr software product.Results and Discussion. It was established that in the main group, in the complicated failure to pass the gestational process, violations of cardiac rhythm variability were detected in 59.7 % of cases. There is an increase in the frequency of very low frequency (VL F) waves (43.5 % relative to control, p<0.05), indicating a predominance of humoral and metabolic rate of regulation of the cardiac rhythm. At the threat of premature births, a decrease in the particle (LF) is observed at 36.6 %, a decrease in the share of high-frequency waves (НF) by 30.8 %. Taking into account the results of the study, one can speak of a decrease in the tone of the sympathetic and parasympathetic nervous system, reducing the influence of the reflexive vegetative level of regulation, which, in turn, indicates the depletion of regulatory mechanisms and the lack of an adaptive protective effect of n.vagus on the heart.Conclusions. Our innovative low-invasive method of evaluating the adaptive reactions of the organism through the determination and analysis of indicators of cardiac rhythm variability in pregnant women with the existing harmful habits offers us the opportunity to observe manifestations of functional stress of regulatory systems of pregnant women, preceding the development of complication of non-delivery of gestational process.

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.

There are presented the results of combined examination of the state of vegetative nervous system in 94 patients with rheumatoid arthritis. By studying the variablity of cardiac rhythm in the sphere of vegetative regulation in patients dominance of sympathic tonicity mainly with asympathicotonic reactivity and deficient vegetative support of activity is determined. In majority of patients (90,4%) symptom complexes of vegetative dysfunction are found. Inclusion of dimephosphonum in combined therapy of rheumatoid arthritis led to normalization of indices of vegetative regulation and to significant diminishing of clinical manifestations of vegetative dysfunction.

Introduction. Psychic retardation and its correction in children is an important problem in children’s psychoneurology. It is necessary to extend the variety of treatment methods, also by means of osteopathy. The analysis of the cardiac rhythm vaiability gives information about the functional state of the body and permits to follow its dynamics.Research objectives. Evoluate the influence of osteopathic treatment on the functional state of children presenting psychic retardation (according to the data of the spectral analysis of the cardiac rhythm variability). Research methods. An osteopathic evaluation and an analisys of the cardiac rhythm variability were held in a group of children presenting psychic retardation (31 boys aged from 5 to 7) before and after three osteopathic consultations. The statistical data processing was held with the use of the Wilcoxon test.Results. All the children presenting psychic retardation had somatic dysfunctions and tension of the body’s regulating systems (according to the evaluation of the data of the cardiac rhythm variability). After the course of osteopathic treatment on the background of correction of somatic dysfunctions all the children presenting psychic retardation showed decrease of the tension of the regulatory systems. The vegetative balance was achieved and the body’s adaptive capabilities improved.Conclusion. The results of the research permit to recommend the use of osteopathic techniques in combined therapy of children presenting psychic retardation, as well as the use of the analysis of the cardiac rhythm variability for evaluation of the effectiveness of osteopathic treatment.
