Key result
Digital signal processing of abdominal ECGs successfully extracted maternal and fetal QRS complexes, revealing a 0.1 Hz rhythm in both and a fetal rhythm synchronous with maternal respiration.

Digital signal processing of abdominal ECGs can successfully extract fetal heart rate variability, revealing physiological interactions between maternal and fetal autonomic nervous systems.
Cerutti et al. (1986) conducted an observational in Healthy pregnancy (n=20). Abdominal ECG recording and digital signal processing was evaluated on Detection of maternal and fetal QRS complexes and HRV spectral analysis. Digital signal processing of abdominal ECGs successfully extracted maternal and fetal QRS complexes, revealing a 0.1 Hz rhythm in both and a fetal rhythm synchronous with maternal respiration.
