Introduction Very preterm babies can be difficult to monitor using standard external Doppler fetal heart tracings (eFHR). External fetal electrocardiogram (fECG) is a potential alternative. Methods This was a prospective observational pilot study of hospitalized patients at 24 to 28 weeks' gestation. A total of 30 women were traced for up to 2 hours using eFHR followed by up to 2 hours using fE...

Objectives: This descriptive study was performed to evaluate the capability of a non-invasive transabdominal electrocardiographic system to extract clear fetal electrocardiographic (FECG) measurements from intrauterine growth restricted (IUGR) fetuses and to assess whether abdominal FECG parameters can be developed as markers for evaluating the fetal cardiac status in IUGR. Methods: Transabdomi...

This letter addresses the problem of fetal electrocardiogram (FECG) extraction. A class of source extraction algorithms is proposed, which uses a combination of two different approaches: Barros’s source extraction approach and Hyvärinen’s fixedpoint approach. The proposed algorithms can rapidly extract the desired FECG with little noise, and can work well in some bad situations. The validity an...

The fetal ECG (fECG) provides a mean to monitor non-invasively the fetal heart activity. Until today, its low signal to noise ratio hampered an extended use of the fECG in clinical practice. As proposed processing methods have shown a lack of accuracy in certain circumstances, the characterization and further development of methods to process the fECG is of high interest. This contribution aims...

Fetal heart rate monitoring yields vital information about the fetus health and can support medical decision making in critical situations. The Fetal Electro Cardio Gram (FECG) signal reflects the electrical activity of the fetal heart. It contains information about the health status of the fetus, so that an early diagnosis of any cardiac defects before delivery increases the effectiveness of t...

FECG (Fetal Electrocardiogram) is weak signal indirect monitored between the electrode that placed upon the mother abdominal the matrix surface, which contains all the forms of jamming signal. How to separate the Fetal from the strong background interference has important value of clinical application, but this is a difficult problem in the signal processing field. Independent Component Analysi...

The Booroola fecundity gene (FecB) and growth differentiation factor 9 (GDF9) gene belong to the transforming growth factor β (TGF-β) superfamily. The mutations of these genes have additive effects on the prolificacy in sheep. The aim of the present study was to determine the possible mutations of FecB and FecG(H) genes in Lory sheep breed of the Lorestan province, Iran. Sixty blood samples wer...

OBJECTIVES The aim of the study was to review clinical and laboratory outcomes of a cohort of fetuses monitored during high-risk labours, simultaneously by fetal electrocardiography (FECG) and routine cardiotocography (CTG). MATERIALS AND METHODS Eighty-three parturients from the Department of Obstetrics and Gynecology of Medical University were included in the clinical study. Inclusive crite...

The fetal heart rate (FHR) is a useful tool in the assessment of the condition of the fetal before and during labour. Fetal Electrocardiography (FECG) (Sureau, 1996) uses noninvasive surface electrodes placed on the maternal abdomen is another tool for FHR recording (Sureau, 1996). The fetal signal is weak relative to the maternal signal and to the competing noise. Widrow et al. (Widrow et al.,...

Fetal heart rate estimated from fetal electrocardiogram (fECG), recorded via electrodes placed on the maternal abdomen, represents an important tool in evaluating fetal distress and diagnosing fetal diseases. However, due to poor signal to noise ratio (SNR) of the fECG, the abdominal fECG analysis is still very difficult, despite of significant advances in technology and in the field of electro...
