The fetal ECG derived from abdominal leads provides an alternative to standard means of fetal monitoring. Furthermore, it permits long-term and ambulant recordings, which expands the range diagnostic possibilities for evaluating the fetal health state. However, due to the temporal and spectral overlap of maternal and fetal signals, the usage of abdominal leads imposes the need for elaborated si...

Longitudinal neurobehavioral development was examined in 237 fetuses of low-risk pregnancies from 2 distinct populations--Baltimore, Maryland, and Lima. Peru--at 20, 24, 28, 32, 36, and 38 weeks gestation. Data were based on digitized Doppler-based fetal heart rate (FHR) and fetal movement (FM). In both groups. FHR declined while variability, episodic accelerations, and FM-FHR coupling increase...

OBJECTIVE To determine the relationship between contraction related changes in fetal heart rate and cerebral oxygenation measured by near-infrared spectroscopy during labour. STUDY DESIGN A specially designed optical probe was inserted through the dilated cervix and placed against the fetal head in 30 women during labour. Alterations in fetal heart rate during the final hour of the first stag...

In this paper, we propose an application of non-parametric Bayesian (NPB) models for classification of fetal heart rate (FHR) recordings. More specifically, we propose models that are used to differentiate between FHR recordings that are from fetuses with or without adverse outcomes. In our work, we rely on models based on hierarchical Dirichlet processes (HDP) and the Chinese restaurant proces...

Sir,—The absolute significance of the findings of Eddleston and colleagues [1] would have been much clearer if they had compared the two extradural groups with a control group which did not receive extradural bupivacainc. Although this control group would have been self-selected and not subject to randomization, the group could have been matched as closely as possible to the two study groups. I...

consensus has formed among sonographers, radiologists, obstetricians, and maternal-fetal medicine subspecialists: screening for fetal heart disease deserves the dubious distinction of being one of the most challenging and least successful aspects of fetal ultrasonography. Because of the challenges inherent with screening the fetus for congenital heart disease (CHD), the rate of prenatal detecti...
