BACKGROUND The fetal anomaly ultrasound only detects 65 to 81 % of the patients with congenital heart disease, making it the most common structural fetal anomaly of which a significant part is missed during prenatal life. Therefore, we need a reliable non-invasive diagnostic method which improves the predictive value for congenital heart diseases early in pregnancy. Fetal electrocardiography co...

The purpose of the study was to compare the accuracy of a noninvasive fetal heart rate monitor with that of ultrasound, using a fetal scalp electrode as the gold standard, in laboring women of varying body habitus, throughout labor and delivery. Laboring women requiring fetal scalp electrode were monitored simultaneously with the investigational device (noninvasive fetal ECG), ultrasound, and f...

conclusions: normothermia and hemodynamic stability are the most important factors which help to reduce fetal loss during open heart surgery in pregnancy. the fetus has an auto-regulation which comes into play when the mother is experiencing shock. objectives: the aim of this study was to report our experience with urgent cardiopulmonary bypass carried out in early pregnancy and to analyze fact...

Fetal well-being was estimated by the enlargement of maternal abdomen, palpation of fetus on the abdomen, maternal perception of fetal kicking, and listening to fetal heart sound with obstetric stethoscope, in old age. Antique diagnosis of fetal life was fetal QRS found on limb lead electrocardiogram (ECG) studied by Cremer, which was progressed to fetal ECG amplifier composed of vacuum tube re...

OBJECTIVES Determination of gestational age-related modulations in fetal heart rate and descending aorta blood flow velocity in the early human fetus and comparison of aortic variability data with data obtained from the umbilical artery. It is hypothesized that these modulations present in the umbilical artery also occur in the descending aorta. METHODS Doppler studies of descending aorta vel...

This study examines prenatal-to-postnatal stability in heart rate and variability from mid-gestation through the first year of life. Fetal heart rate data were collected from 52 healthy fetuses at 24, 30, and 36 weeks gestation, and again at 2 weeks and 12 months of age. Fetal heart rate measures were stable during gestation and positively associated with neonatal and infant measures. Maternal ...
