چکیده

A high-precision method is presented for the extraction of the fetal electrocardiogram from multi-channel potential recordings on the mother's skin. First the problem is appropriately formulated in terms of blind source separation, where the sources can have a multi-dimensional nature. As a summary of preceding work it is shown how the fetal electrocardiogram can be reconstructed by means of second-order tools. However an extra higher-order processing step enhances the accuracy and allows to identify the transfer from source to electrode. The method is illustrated with an example.

Fetal ECG Extraction by Combining Single-Channel SVD and Cyclostationarity-Based Blind Source Separation

Fetal Electrocardiogram (FECG) can provide important clinical information for the assessment of fetal well-being. However, the extraction of FECG from the maternal abdominal wall remains an open problem due to various kinds of interferences and noises, where the maternal Electrocardiogram (MECG) is the dominant source of interference. In this study, a novel FECG extraction framework by combinin...

Fetal ECG Extraction Using Independent Component Analysis

An electrocardiogram (ECG) signal contains the electrical activity generated by the contraction of heart muscles. An ECG signal can provide a lot of information about an individual's heart condition and health. That being said, principles of ECG analysis can also be applied to the electrocardiogram of a fetus (FECG) in order to accurately monitor heart development and health during the differen...

Obstetricians were asking the engineering support to study more extensively any technical possibility to electronically get some useful information from the whole PQRST complex of the fetal electrocardiogram (fECG) in order to identify eventual sign of fetal distress (FD). The latter should indeed be found as a more reliable information for the clinician with the potential benefit of increasing...
