Access to reliable and easily extractable fetal electrocardiogram recordings would help the physician better determine fetal heart conditions and diagnose fetal cardiac defects early in the pregnancy. This book presents a novel method for automatically extracting beat-to-beat fetal electrocardiogram from maternal surface electrodes down to gestation week twenty and possibly earlier. Extraction is based on a two-stage blind adaptive filtering algorithm, the first stage using frequency-domain electrocardiogram features and the second considering time-domain features. Extraction has succeeded in...
