An Algorithm for Extracting Fetal Electrocardiogram
Neurocomputing, 2008The extraction of fetal electrocardiogram (FECG) from the composite maternal ECG signal is discussed. This problem can be modelled from the perspective of blind source extraction. An important and primary work is done by Barros and Cichocki, who propose an FECG extraction method for the noisy-free mixing model.

In 1906, Cremer1first recorded fetal deflections of about 0.5 mm. amplitude superimposed on the maternal electrocardiogram of nine-month gravid women by a string galvanometer electrocardiograph taking abdominovaginal and abdominorectal leads. Since then others2-10have tried various methods with different instruments, such as special electrocardiograph ...

CURRENT INTEREST in the field of human reproduction has created greater demands for accurate evaluation of intrauterine environment. The fetal heart has served as the main indicator of abnormal fetal physiology by evidencing altered myocardial contractility, producing both bradycardia and tachycardia, as well as irregularities in rate.

EXPERIENCES IN THE DIAGNOSIS OF FETAL LIFE WITH THE FETAL ELECTROCARDIOGRAM
Obstetrical & Gynecological Survey, 1960Abstract 1. Twenty-five instances in which the technique of fetal electrocardiography was used for the diagnosis of fetal life, because fetal heart tones could not be heard, are presented and discussed. 2. It was shown that the positive fetal electrocardiograms which could be expected in a number of these instances were evidence for the ...

Signal processing of the fetal electrocardiogram
Journal of Electrocardiology, 1990There has been considerable interest in recent years in the monitoring of the well-being of the fetus by the analysis of changes in morphology of the fetal electrocardiogram (FECG) signal. In this article, a brief review is first made of the use of the scalp electrode method to obtain an enhanced FECG complex.

Spectral analysis of the fetal electrocardiogram
Computers in Biology and Medicine, 1989The spectral curves of the averaged fetal and maternal electrocardiograms as recorded from the abdomen were studied. The power spectrums were obtained using a technique which includes the subtraction of an averaged maternal ECG waveform using cross-correlation function and fast Fourier transform algorithm.

A noninvasive extraction of the fetal electrocardiogram
Computers and Biomedical Research, 1977Abstract A noninvasive fetal ECG detection method is described. Three linearly independent thoracic signals orthogonalized by the Gram-Schmidt procedure are generated together with the proper coefficients for which to represent the abdominal ECG. This expansion is used in the cancellation of the maternal portion of the abdominal ECG.

THE FETAL ELECTROCARDIOGRAM IN MULTIPLE PREGNANCY
Obstetrical & Gynecological Survey, 1959Abstract 1. 1. The fetal electrocardiogram is shown to be a useful tool in the study of multiple pregnancy. 2. 2. Recordings from 9 sets of twins, one set of triplets, and one set of quadruplets are presented. 3. 3. Diagnosis of a twin pregnancy at 16 weeks is demonstrated. 4. 4.

The use of the fetal electrocardiogram in labour
BJOG: An International Journal of Obstetrics & Gynaecology, 1994It is clear that considerably more work needs to be done before fetal ECG waveform analysis can be adopted for the purposes of routine fetal monitoring. It must be decided exactly what we want fetal ECG waveform analysis to achieve. If it is to reduce the number of operative deliveries performed in the presence of normal or intermediate CTG patterns ...
