Abstract
Maternal and fetal QRSs are detected through linear filtering and averaging techniques from the abdominal ECG recording after the 25th week of gestation. Heart rate variability (HRV) signals are hence obtained for the two series in the form of an R-R interval function. Bivariate spectral analysis using autoregressive modeling is then carried out to enhance possible correlations between material and fetal control of heart rate elicited by the respective autonomic nervous systems. These methods allow a quantitative analysis of rhythm disturbances, a measure of breathing activity of the fetus and its reactivity in the respiratory range of the mother.
