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...

Fetal heart rate (FHR) is the main feature for monitoring fetal well-being as recommended by International Federation of Gynecology and Obstetrics (FIGO). The ultrasound based cardiotocography (CTG) nowadays world-wide non-invasive clinical reference technique intrapartum FHR monitoring, stated FIGO. However, some limitations CTG have justified interest alternative solutions, on abdominal elect...

The non-invasive Fetal Electrocardiogram (FECG) signal has become a significant method for monitoring the fetus's physiological conditions, extracted from Abdominal (AECG) during pregnancy. current techniques are limited delivery detecting and analyzing fECG. non - intrusive fECG recorded mother's abdomen is contaminated by variety of noise sources, can be more challenging task removing materna...

The feasibility and accuracy of long-term transabdominal fetal electrocardiogram (fECG) recordings throughout pregnancy were studied using a portable fECG monitor. Fifteen-hour recordings of fetal heart rate (FHR) were performed in 150 pregnant women at 20-40 weeks of gestation and 1-hour recordings were performed in 22 women in labour and compared with simultaneous scalp electrode recordings. ...

Fetal heart monitoring yields vital information about the fetus health and can support medical decision making in critical situations. A compound signal is obtained non-invasively by placing electrodes on the abdomen area of the mother which contains maternal and fetal ECG signals contaminated by various other signals from body and externally induced noises. The Polynomial Networks technique ha...

The fetal electrocardiogram (FECG) signal reflects the electrical activity of the fetal heart. It contains information about the health status of the fetus and therefore, an early diagnosis of any cardiac defects before delivery increases the effectiveness of the appropriate treatment. The proposed approach extracts the FECG from two ECG signals recorded at the thoracic and abdominal areas of t...

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...

Monitoring of fetal heart rate (FHR) is an important measure of fetal wellbeing during the months of pregnancy. Previous works on estimating FHR variability from Doppler ultrasound (DUS) signal mainly through autocorrelation analysis showed low accuracy when compared with heart rate variability (HRV) computed from fetal electrocardiography (fECG). In this work, we proposed a method based on emp...

This paper presents a novel method for extracting the fetal ECG (FECG) from a single-lead abdominal signal. A dynamical model for a modified abdominal signal is proposed, in which both the maternal ECG (MECG) and the FECG are modeled, and then a parallel marginalized particle filter (par-MPF) is used for tracking the abdominal signal. Finally, the FECG and MECG are simultaneously separated. Sev...

The electric fetal heart activity was firstly recorded as tiny deflections on maternal limb lead electrocardifogram (ECG) by Cremer [1], direct lead fetal ECG with needle electrode by Caldeyro-Barcia et al. [2] and with scalp lead clip electrode by Hon [3]. Indirect maternal abdominal lead fetal ECG (fECG) was recorded by Maeda and Nakano [4] and others. Intrapartum fetal heart rate (FHR) was m...
