Diagnostic and prognostic value of analysis of heart rhythm variability in pregnant patients under estimation of fetal hypoxia evidence

The correlation between fetal hypoxia degrees according to the data of cardiotocography and status of mother's vegetative nervous system as a result of heart rhythm variability research have been analyzed. It has been revealed that during the increase of fetal hypoxia severity, mother has observed activation of sympathetic section of vegetative nervous system, which has changed by vagotonia in severe and terminal states. These findings can be used both for indirect estimation of fetal hypoxia severity and for its course prognosis
