The objective: is to analyze the frequency of gestational complications and labor abnormalities in pregnant women with different types of autonomic regulation disorders. Materials and methods. 129 women were examined. The type of autonomic regulation was determined by recording the time and spectral parameters of heart rate variability by computer cardiointervalography with use of CardioLab Bebicard diagnostic system. The main group consisted of 66 pregnant women with established autonomic regulation disorders. 63 patients with a normal autonomic state, a balanced level of sympathetic and parasympathetic activity formed a control group. To assess the status of the mother-placenta-fetus, an ultrasound examination with doplerometry was performed. Results. A significant increase of the central regulatory activity in pregnant women with autonomic dysfunction was established. The cardiointervalography indicate a balanced activity of the autonomic nervous system in the control group. The gestational complications were significantly more frequent in women of the main group in the context of detected autonomic dysfunction than in the control group. Labor anomalies were more common in pregnant women of the main group. Women with high parasympathetic astivity noted an increased frequency of labor dystocia. In patients with a superiority of sympathetic and humoral regulation, an increased frequency of labour activity weakness was observed. The fast deliveries often determined in pregnant women with decreased activity of both departments of autonomic nervous system. The incidence of urgent caesarian deliveries was significantly higher in the main group, including due to the ineffectiveness of the medical correction of labor abnormalities. Conclusions. The cardiointervalography is informative for the diagnosis of autonomous regulation and adaptive disorders, which may be the prerequisites for the gestational complications and labor abnormalities development. Using the heart rate variability analys is in pregnant women will improve the early prediction of gestational pathology and pathological birth process, reduce the risk of obstetric and perinatal complications. Key words: heart rate variability, autonomic regulation, gestational complications, labor activity abnormalities.

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.

The objective: was to evaluate the effectiveness of various anesthesia options for laparoscopic hysterectomy, including low-opioid (LOA) and opioid-free anesthesia (OFA) by studying the dynamics of heart rate variability (HRV) indicators.Materials and methods. 102 patients were randomly assigned to 3 groups: 37 patients who received standard opioid anesthesia (control group), 33 women who received the LOA group, and 32 patients who received OFA.Results. Laparoscopic hysterectomy is accompanied by tension of the autonomic nervous system, especially its sympathetic link, which is manifested by an increase in the index of vago-sympathetic interaction at the traumatic stage of the operation. These changes were most significant in patients who received standard and opioid-free anesthesia, which indirectly indicates insufficient stress protection of these types of intraoperative anesthesia.Conclusions. The use of low-opioid anesthesia is accompanied by a greater stabilization of HRV indices, which indicates its sufficient autonomic protection during laparoscopic hysterectomy than standard and opioid-free anesthesia.

Abstract   Within the framework of the research into pathological conditions and syndromes associated with undifferentiated connective tissue dysplasia (UCTD), an emphasis needs to be placed on the changes in heart rhythm. In puberty, the severity of neurovegetative disorders caused by the presence of UCTD might increase manifold. The features of heart rate variability (HRV) in pubertal children against the background of UCTD have been studied insufficiently and require more detailed analysis. This study aims to assess heart rate variability and tone of the autonomic nervous system (ANS) in puberty-aged children with UCTD. Two groups of children were examined, with methods including electrocardiography and cardiointervalography. The main group consisted of 36 puberty-aged children with UCTD, the control group consisted of 30 healthy children. ANS tone was assessed based on the HRV. In the control group of children aged 11, the value of variation range (VR) was 0.18±0.4, mode amplitude (MA) 35.2±2.4, stress index (IN) 72.8±4.3, which corresponds to the state of vegetative balance. As the puberty progresses, the state of eutonia is replaced by the activation of the sympathetic division of the ANS, which becomes most pronounced at the age of 13 years. In the control group of children aged 13, the value of VR was 0.08±0.02, MA 61.7±2.1, SI 210.6±8.6, which corresponds to moderate sympathicotonia. By the end of puberty, in healthy children, the severity of sympathetic activation begins to decrease, and at the age of 15 years, vegetative balance is again observed. However, this pattern is violated in children with UCTD. Upon entering puberty, moderate activation of the sympathetic division of the ANS is already observed in children with UCTD. At the age of 11 years in this group, the value of VR is 0.06±0.02, MA 72.4±3.1, SI 211.2±8.6. At the age of 13, pronounced sympathicotonia is observed, which is confirmed by the values of VR - 0.04±0.01, MA 80.2±4.3 and SI 34.3±14.7. By the end of puberty in children with UCTD, in contrast to the control group, the analyzed parameters indicate not an equilibrium of the ANS, but the predominance of parasympathetic activation. The research provides an insight into heart rate variability in puberty-aged children with UCTD. It was established that healthy children enter puberty in a state of equilibrium of the autonomic nervous system, which in the middle of puberty is replaced by moderate sympathicotonia, and then returns to its original values. Children with the presence of UCTD enter puberty with moderately pronounced sympathicotonia, which gradually increases to pronounced values and is replaced by moderate vagotonia.

Abstract We compared heart rate variability parameters of patients with spina bifida with those of a control group during urodynamic study to evaluate the autonomic nervous system dysfunction of spina bifida. Continuous heart rate variability parameters were recorded during 3 successive periods (P0: 2 minutes before the start of filling; P1: start of filling to the first desire to void; P2: P1 to the end of filling or the start of voiding). Children with vesicoureteral reflux who underwent video-urodynamic study were established as a control group. We included 11 patients with spina bifida and 9 controls. At baseline, patients with spina bifida had lower values of RMSSD, pNN50, and HF, while LF/HF ratio was increased (5.04 ± 4.75 vs 0.67 ± 0.42, p = 0.014). During bladder filling, LF/HF values increased in the control group (P0 0.67 ± 0.42 vs P1 0.89 ± 0.34 vs P2 1.21 ± 0.64, p = 0.018) while it was decreased in spina bifida patients (P0 5.04 ± 4.75 vs P1 3.96 ± 4.35 vs P2 3.26 ± 4.03, p < 0.001). HF were significantly increased in spina bifida children during bladder filling (p = 0.002). In time domain, SDNN was increased only in control group during bladder filling. Parasympathetic activity domains were decreased in children with spina bifida at baseline. During the bladder filling phase, parasympathetic activity increased with fixed sympathetic activity in spina bifida group while the control group demonstrated a shifted balance toward sympathetic preponderance at the end of bladder filling. These findings may be related to the pathophysiology of neurogenic bladder in spina bifida.

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.

Heart rate variability (HRV) was compared in 30 subjects receiving external Qi therapy (EQT) or placebo control therapy, in a crossover design experiment. Subjects who received the EQT reported more pleasant and calm emotions than did the placebo group. Qi therapy reduced the heart rate and increased HRV as indicated by a reduced low frequency/high frequency power ratio of HRV. With nonlinear analysis, the Poincaré plot index of HRV and approximate entropy was greater in the EQT group than in the control group. These findings suggest that EQT stabilizes the sympathovagal function and cardiac autonomic nervous system by inducing more positive emotions than the placebo therapy. In conclusion, EQT may act by stabilizing both the autonomic nervous system and the emotional state.

The aim of the study was twofold: first, to compare the activity of the autonomic nervous system (ANS) between the population self-declared as electrohypersensitive (EHS) and their matched control individuals without intended exposure to electromagnetic fields (EMF). The second objective was to determine whether acute exposure to different radiofrequency signals modifies ANS activity in EHS. For that purpose, two different experiments were undertaken, in which ANS activity was assessed through heart rate variability (HRV) and skin conductance (SC). In the first experiment, a comparison between the EHS group ( n = 30) and the control group ( n = 25) showed that the EHS has an increased number of responses to auditory stimuli as measured by skin conductance activity, and that none of the short-term heart rate variability parameters differ between the two matched study groups. The second experiment, performed in a shielded chamber, involved 10 EHS from the first experiment. The volunteers participated in two different sessions (sham and exposure). The participants were consecutively exposed to four EMF signals (GSM 900, GSM 1800, DECT, and Wi-Fi) at environmental level (1 V/m). The experiment was double blinded and counterbalanced. The HRV variables studied did not differ between the two sessions. Concerning electrodermal activity, the data issued from skin conductance and tonic activity did not differ between the sessions, but showed a time variability. In conclusion, the HRV and SC profiles did not significantly differ between the EHS and control populations under no exposure. Exposure did not have an effect on the ANS parameters we have explored. NEW & NOTEWORTHY This study provided analysis on the skin conductance parameters using a newly developed method (peak/min, extraction of skin conductance responses) that had not been performed previously. Additionally, the skin conductance signal was decomposed, considering tonic and phasic activities to be a distinct compound. Moreover, this is the first time a study has been designed into two steps to understand whether the autonomic nervous system is disturbed in the EHS population.

Acupressure applied on the Extra 1 acupuncture point results in sedation, thereby reducing bispectral index (BIS) values. Mental status and hypnotic agents influence the autonomic nervous system. We hypothesized that acupressure at the Extra 1 point would induce sedation and change sympatho-parasympathetic nerve balance. We investigated the effect of acupressure at the Extra 1 point on the EEG spectral entropy values and heart rate variability (HRV). Forty-eight volunteers (24 males and 24 females) were randomly assigned to the control or Extra 1 group. The control group received acupressure at a sham point and the Extra 1 group received acupressure at the Extra 1 point. Acupressure was applied for 5 min. The record of the EEG spectral entropy values and HRV started 5 min before acupressure and stopped 5 min after acupressure. Acupressure significantly reduced the EEG spectral entropy values in both groups, but the values of the Extra 1 group were significantly smaller than those of the control group (P< .01). Acupressure significantly decreased the LF/HF ratio of HRV in both groups (P< .05). When divided upon gender, although acupressure tended to decrease the LF/HF ratio, the ratio significantly decreased during and after acupressure only in females of the Extra 1 group (P< .05). We concluded that acupressure on the Extra 1 point significantly reduced the EEG spectral entropy in both the genders, but affected the LF/HF ratio of HRV only in females.
