The objective: to establish the features of fetus functional state definition in pregnant women with perinatal losses in history. Patients and methods. 89 pregnant women with perinatal losses in history were screened. The fetus functional status evaluation was based on cardiotocography and definition of fetal heart rate variability by cardiointervalography. Results. Received data showed the decrease of SDNN, RMSSD and pNN50 in pregnant women with perinatal losses in history, indicating the prevalence of parasympathetic effects on the fetal myocardium (p<0.05). Studies of mathematical time characteristics of fetal heart rate revealed a significant overweight of the metabolic-humoral regulatory circuit in women with normal pregnancy (p<0.05). Dynamic stress index evaluation indicates the centralization of heart rate regulation and significant intensity of the fetal compensatory mechanisms in pregnant women with perinatal losses in history. The cardiotocography revealed no difference between the fetal status in women of comparative groups (p>0.05). Conclusions. In pregnant women with perinatal losses in history owing to autonomic nervous system disregulation a significant intensity of fetal regulatory systems and the centralization of fetal cardiac rhythm control were observed. The cardiotocography and cardiointervalography data with revealed signs of excessive sympathetic activation can serve as preclinical signs of gestational pathology. Key words: perinatal losses, fetal functional state evaluation, cardiotocography, cardiointervalography, autonomic nervous system.

The Asymmetry

The fetal autonomic nervous system responds to uterine contractions during active labor as identified by changes in the accelerations and decelerations of fetal heart rate (FHR). Thus, this exploratory study aimed to characterize the asymmetry differences of beat-to-beat FHR accelerations and decelerations in preterm and term fetuses during active labor. In an observational study, we analyzed 10 min of fetal R-R series collected from women during active preterm labor (32–36 weeks of pregnancy, n = 17) and active term labor (38–40 weeks or pregnancy, n = 27). These data were used to calculate the Deceleration Reserve (DR), which is a novel parameter that quantifies the asymmetry of the average acceleration and deceleration capacity of the heart. In addition, relevant multiscale asymmetric indices of FHR were also computed. Lower values of DR, calculated with the input parameters of T = 50 and s = 10, were associated with labor occurring at the preterm condition (p = 0.0131). Multiscale asymmetry indices also confirmed significant (p < 0.05) differences in the asymmetry of FHR. Fetuses during moderate premature labor may experience more decaying R-R trends and a lower magnitude of decelerations compared to term fetuses. These differences of FHR dynamics might be related to the immaturity of the fetal cardiac autonomic nervous system as identified by this system response to the intense uterine activity at active labor.

Mouse Fetuses

Heart rate is controlled by the activity of the autonomic nervous system: the sympathetic and parasympathetic nervous systems increase and suppress heart rate, respectively. To evaluate the activity of the autonomic nervous system, it is possible to determine heart rate variability using electrocardiography (ECG). During the fetal period, the heart and autonomic nerves develop in coordination; however, physiological changes, including autonomic nervous activities that occur during the fetal stage, remain largely unknown. Therefore, in this study, we measured ECG signals of mouse fetuses using our established method to evaluate the development of heart rate and autonomic nervous activity at different fetal developmental stages. We found that heart rate was significantly increased in fetal mice at embryonic day (E) 18.5 compared with that at E13.5, E15.5, and E17.5, indicating that fetal heart rate increases only at the stage immediately prior to birth. Interestingly, fetal parasympathetic nervous activity was reduced at E17.5 and E18.5 compared with that at E13.5, whereas fetal sympathetic nervous activity remained unchanged, at least from E13.5 to E18.5. These results indicate that parasympathetic activity rather than sympathetic activity affects fetal heart rate and that the decrease in parasympathetic activity toward the end of pregnancy could result in the observed increase in fetal heart rate.

Autonomic Nervous

The article presents an analysis of autonomic regulation of heart rate against preventive procedures in university teachers. Aim. The paper aims to identify the features of autonomic regulation of heart rate in university teachers when using preventive measures. Materials and methods. The study involved 87 teachers aged from 25 to 60 years. The participants were divided into three subgroups depending on their professional experience. The functional status of the autonomic nervous system was assessed with the method of variational pulsometry using the UPFT-1/30 – Psychophysiologist. Dynamic electroneurostimulation through the DENAS-Vertebra-02 apparatus was used as preventive measures. Results. Under the effect of dynamic electroneurostimulation, distinct trends were formed to improve the functional status of the autonomic nervous system in teachers with the professional experience of 10–20 years. For specia­lists with the experience of 21–30 years and more a course of electric massage sessions was not enough or it could be combined with other means of relaxation. Conclusion. As preventive measures for teachers, dynamic electroneurostimulation can be used (DENAS-Vertebra-02), which obviously improves the functional state of the autonomic nervous system of teachers with professional experience of 10–20 years.
