The objective of this work was to study circadian rhythms of the indicators of the spectral analysis of the heart rate variability in case of depression. Materials and methods. A total of 37 patients, with a mean age of 46.7±10.3 years, were examined. According to the International Classification of Disease, 10th revision (ICD-10), endogenous depression was diagnosed for all of them (F 31.3–31.4, F 32.0–32.2, F 33.0–33.2). To assess the variability of the heart rhythm, the spectral analysis was used. The patients were examined at 1 AM, 7 AM, 1 PM, 7 PM prior to the beginning of treatment, following one week, and upon leaving the inpatient department. The control group consisted of 15 mentally healthy people. Results. Before the beginning of treatment, desynchronization of circadian rhythms of the indicators studied and the sleep-wake cycle, the increase in the spectrum power within lowfrequency (LF) range, and the decrease in the spectrum power within high-frequency (HF) range were observed. Reduction of depression symptoms was followed by resynchronization of the rhythms under study, with a spectrum power within LF range being increased and that within HF range – decreased. Conclusions. Changes in depression symptoms and chronobiological disorders testify to their close pathogenetic link.

Objectives To clarify changes in the cardiovascular autonomic nervous system function due to trigger point acupuncture, we evaluated differences in responses between acupuncture at trigger points and those at other sites using spectral analysis of heart rate variability. Methods Subjects were 35 healthy men. Before measurements began the subjects were assigned to a trigger point acupuncture or control group based on the presence/absence of referred pain on applying pressure to a taut band within the right tibialis anterior muscle. The measurements were conducted in a room with a temperature of 25°C, with subjects in a long sitting position after 10 min rest. Acupuncture needles were retained for 10 min at two sites on the right tibialis anterior muscle. ECG was performed simultaneously with measurements of blood pressure and the respiratory cycle. Based on the R–R interval on the ECG, frequency analysis was performed, low-frequency (LF) and high-frequency (HF) components were extracted and the ratio of LF to HF components (LF/HF) was evaluated. Results The trigger point acupuncture group showed a transient decrease in heart rate and an increase in the HF component but no significant changes in LF/HF. In the control group, no significant changes were observed in heart rate, the HF component or LF/HF. There were no consistent changes in systolic or diastolic blood pressure in either group. Conclusions These data suggest that acupuncture stimulation of trigger points of the tibialis anterior muscle transiently increases parasympathetic nerve activity.

Objective. The high prevalence of obesity in employable population dictates the necessity for preclinical diagnosis of diseases associated with it, including the study of the autonomic regulation of heart rhythm. The objective was to study the correlations between the adipocytokine profile and heart rate variability in patients with obesity. Materials and methods. 300 persons were examined, the average age was 46.2 6.4 years; Group 1 was metabolically unhealthy obesity phenotype (MUHOP) 90 patients; group 2 was obesity without metabolic disorders [Ob(+)MD(-)] (MHOP) 50 persons; the control group consisted of 100 healthy respondents. We studied the following indices: blood serum adipocytokines: leptin, insulin, resistin, adiponectin. Heart rate variability was studied using Poly-Spectrum Rhythm 2012 computer electrocardiograph. Results. In the course of the study, decrease in the total heart rate variability and reactivity of the parasympathetic part of the autonomic nervous system in patients from MUHOP group was found, while there were no differences with the control in the MHOP group. It was established that a decrease in the parasympathetic effect on the regulation of heart rhythm is associated with the presence of abdominal obesity, insulin resistance, and an increase in the level of TG, glucose, resistin, and uric acid. Conclusions. The received relationships between indicators of carbohydrate and lipid metabolism, the level of uric acid and adipocytokines with temporal and spectral characteristics of the autonomic nervous system confirm their contribution to the development of autonomic dysfunction in obese persons.

Objective. To study heart rhythm variability (HRV) in ethnic groups of pregnant women with and without arterial hypertension during all gestation period. Design and methods. 100 pregnant Russian and Buryat women with arterial hypertension formed the main group. The control group included 100 healthy pregnant women with a normal current of pregnancy, without arterial hypertensions. All subjects underwent Holter ECG monitoring («Incart», «Kardiotechnika-04-BP-3», Russia). Results. There is a significant decrease in time parameters of rhythm variability n pregnant Buryat women with arterial hypertension in the second trimester. In the third trimester of pregnancy heart rhythm variability is higher in hypertensive women compared to those without hypertension. In Russian population indicators of heart rate variability do not vary during the day. In an ethnic group of women with arterial hypertension an increase of indicators of low and high frequencies due to the prevalence of vascular sympathetic regulation is observed in the first trimester of pregnancy. Conclusions. Pregnant women of the Buryat population with arterial hypertension have lower heart rhythm variability in the first and second trimesters of pregnancy. In Russian population the variability parameters do not change.

Objective: to assess the features of initial vegetative tone and vegetative reactivity in sportsmen during their endurance training and speed-power physical exercises. Material and methods. We examined 50 sportsmen (22 athletes и 28 rowers) and 29 young men of the control group. The parameters of heart rate variability were evaluated by the results of ECG registration during conduction of the orthostatic test (complex «Polyspectr»). Results . The initial vegetative tone in speed-power sportsmen is characterized by more expressed activity of autonomic regulation of heart rhythm, and vegetative reactivity is characterized by higher degree of humoral-metabolic regulation mechanisms than in sportsmen specializing in endurance training. Conclusion. The features of the parameters of heart rate variability during the orthostatic test have been determined in dependence on the direction of the training process.

The initial vegetative tonus and vegetative reactivity were studied in patients with neuroreflectory syncopal states (NSS) during passive orthostatic testing in the orthostatic and clinical phases. The variability of the heart rhythm was estimated on the Neiron-spektr device. During the orthostatic testing, the insufficient activity of the sympathetic part of the nervous system in NSS patients was observed compared to the control group. During the clinostatic testing, the indices of NSS patients approached the normal values.
