preterm birth is the leading cause of death among children, accounting for 18% of all deaths among children aged under five years and as many as 35% of all deaths among newborns. Therefore, vigorous heart rate monitoring helps determine the fetus's safety. Hence, owing to the ...
For many years, assessment of the fetal heart rate was limited to the fetoscope, a direct stethoscope attributed to Adolphe Pinard in 1876. In 1957, Orvan Hess and Ed Hon at Yale University introduced electronic fetal heart rate monitoring as a window into the status of the fetus (Hon and...
By the fifth week of pregnancy, the fetus (usually called an embryo by doctors at this stage) begins to have cardiac activity, though it's coming from a tube-shaped structure rather than a four-chambered heart. The heart continues to develop over the next 4-6 weeks. You often can't he...
s curseFetal heart rateDecreased heart rate variability and increased heart rate recorded in a fetus throughout the third trime-non turned out to be rare prenatal manifestations of a case of Ondine’s curse (chronic central alveolar hypoventilation syndrome), a disorder of still unclear ...
Intrapartum assessment of fetal well-being has evolved over the last 40 years, with the primary focus being fetal heart rate assessments. Despite widespread use and initial enthusiasm for the potential for heart rate monitoring to reduce fetal and neonatal mortality and morbidity, conclusive evidence ...
Aim of this work was to investigate whether controlled paced maternal respiration has an effect on the occurrence of fetal-maternal heart rate synchronization. In 6 healthy pregnant women (34th - 40th week of gestation) we obtained simultaneous 5 min. fetal and maternal magnetocardiograms (MCG) ...

and maintained with 1–3% isoflurane and 5–6 L/min O2. Ewes were monitored by heart rate, blood pressure, pulse oximetry and end-tidal capnography. Ultrasound was then used to determine litter size, and if multiples were detected, to decide which fetus had the best lie for coil implanta...
The exams were performed within a month of the start and end of the exercise program, which consisted of 60-min sessions of aerobic exercise on a treadmill and resistance training three times a week for six months. The goal was to reach the patients’ heart rate target zone during training...
Different acupuncture points are used depending on which week of her pregnancy the patient is in. (Note: I never use abdominal points on the abdomen of a pregnant woman.) For example, at 24 weeks the fetus is at the level of the umbilicus and by 32 weeks it is between the umbilicus an...
