A Digital System for Enhancing the Fetal Electrocardiogram

IEEE Transactions on Biomedical Engineering, 1969
In order to see the true nature of the fetal electrocardiogram, many varied signal enhancement techniques have been tried. Recently, through the use of coherent time averaging, the successful recovery of the low-voltage portions of the fetal ECG has been demonstrated. The averaging device which has been used has limitations with respect to the recovery

Lead systems for the abdominal fetal electrocardiogram

Clinical Physics and Physiological Measurement, 1989
The literature on abdominal FECG has been studied for design principals of a lead system for recording FECG signals at the maternal abdomen. The indications are compared, contrasted, and combined with the results obtained from basic FECG data collected in a recent study on the modelling of the FECG.

Digital signal enchancement of the fetal electrocardiogram

American Journal of Obstetrics and Gynecology, 1968
Abstract The use of the fetal electrocardiogram as a diagnostic tool has been limited by the noise which obscures the low-voltage portions of the fetal complexes when they are recorded. Recently, coherent averaging techniques for fetal signal enhancement have shown promise.

Fetal electrocardiogram waveform analysis in labour

Current Opinion in Obstetrics & Gynecology, 2001
The fetal electrocardiogram recorded during labour has so far been used for heart rate recording only. Extensive experimental, bioengineering and clinical research for more than 25 years on changes in the morphology of the electrocardiogram have provided more detailed information on fetal reactions to the stress and strain of labour.

The clinical relevance of the abdominal fetal electrocardiogram.

Journal of perinatal medicine, 1986
We investigated the duration of fetal electrocardiographic events during normal pregnancies and during pregnancies with fetal abnormalities. The fetal abdominal signal was processed and enhanced by means of the averaging technique after removing the maternal complex. In normal pregnancies P wave and QRS complex duration increases progressively from the
