Beschreibung:

Access to reliable and easily extractable fetalelectrocardiogram recordings would help the physician betterdetermine fetal heart conditions and diagnose fetal cardiac defectsearly in the pregnancy. This book presents a novel method forautomatically extracting beat-to-beat fetal electrocardiogram frommaternal surface electrodes down to gestation week twenty andpossibly earlier. Extraction is based on a two-stage blind adaptivefiltering algorithm, the first stage using frequency-domainelectrocardiogram features and the second considering time-domainfeatures. Extraction has succeeded in all available real data setsfrom patients. The combined filter also allowed the identificationof diagnostically important PR, QT, QS and RR durations. This bookshould be useful to researchers, engineers, and physicians who maybe interested in the noninvasive extraction and the early diagnosisof fetal electrocardiogram.
