Assessment Of The Maternal Heart Rate Variability As An Indicator To The Vitality Of The Newborn Immediately After Birth

Abstract
The maternal heart rate variability (HRV) analysis may represent a noninvasive method to evaluate the biological conditions of the newborn and of the mother during childbirth. The Apgar score is a method to establish the vitality of the newborn. The range of this score is from zero to 10. To correlate the maternal HRV and the vitality of the newborn can be helpful for the obstetric and the pediatric during the labor. In this work were used RR intervals time series from 76 women in the hospital admission for delivery. The newborns were divided into two groups: not good vitality (Apgar score equal or below six) and good vitality (more than six). Assess the HRV as an indicator to newborn vitality was made by Receiver Operator Characteristic. In this work were used the parameters of the time series set from time and frequency domain methods divided into two groups according the Apgar score of the newborns. The parameters HF (related to parasympathetic nervous system) and NN50 (number of pairs of the RR intervals that differ by more than 50 ms) displayed sensibility and specificity more than 60% when HRV parameter was related to two groups of newborns. Besides good accuracy in the tests, the HRV analysis made it possible to significantly (p < 0.05) distinguish the group of participants with newborns with not good vitality than good vitality, suggesting that there is correlation between maternal HRV (time and frequency methods) and newborn vitality.
