THE GESTATIONAL PROCESS IN PREGNANT WOMEN WITH DISORDERS OF THE HEART RATE VARIABILITY
Journal Title: World Science - Year 2018, Vol 4, Issue 7
Abstract
Aim of the study: To analyze the pregnancy course in women with the autonomic regulation dysfunction, diagnosed by cardiointervalography and heart rate variability changes. Materials and methods. 102 pregnant women were examined. The initial autonomic status was estimated by registration of time and spectral parameters of heart rate variability applying the computer cardiointervalography and CardioLab BabyCard diagnostic system. The I (main) group consisted of 48 pregnant women with established disorders of autonomous regulation. 54 patients with a normal state of autonomic supply, a balanced level of sympathetic and parasympathetic activity and an optimal level of regulatory systems functioning formed a II (control) group. To assess the condition of the mother-placenta-fetus system an ultrasound examination with doplerometry was performed. Results. Heart rate variability has established a significant increase of central regulatory circuit activity in pregnant women with autonomic dysfunction. Hyperfunction of the sympathetic department in women of the main group was accompanied by exhaustion of compensatory vagal influences. The obtained values of VLF testify about the psycho-emotional stress and cerebral cortex functional disorders existence in these women. Cardiointervalography data in the control group indicate for a balanced activity of the autonomic nervous system. The complications of pregnancy were significantly more frequent in women of the main group in the context of detected autonomic dysfunction. Conclusions. Cardiointervalography is informative for the detection of autonomic regulation disorders, adaptive disorders and changes of hemodynamic responses in mother-placenta-fetus system. Using the analysis of heart rate variability in pregnant women will improve the early prediction of gestational pathology, reduce the risk of obstetric and perinatal complications.
