Key result
The BSSR method extracted fetal ECG signals with a significantly higher correlation to directly recorded scalp ECGs compared to nonholonomic ICA (r=0.88 vs 0.74, p<0.01).
Why the study?
Does a novel extraction method using maternal ECG cancellation and BSSR accurately extract fetal ECG from abdominal composite signals compared to direct recording?

A novel signal processing method combining maternal ECG cancellation and blind source separation accurately extracts fetal ECG components from abdominal signals.
Sato et al. (2006) studied Pregnancy (fetal ECG monitoring) (n=37). Blind source separation with reference signal (BSSR) vs. Nonholonomic independent component analysis (ICA) was evaluated on Correlation coefficient with directly recorded fetal scalp ECG (p=<0.01). The BSSR method extracted fetal ECG signals with a significantly higher correlation to directly recorded scalp ECGs compared to nonholonomic ICA (r=0.88 vs 0.74, p<0.01).
