Ethnicity and fetal heart rate variation
Obstetrics & Gynecology, 1998To determine the effect of ethnicity on fetal heart rate (FHR) variation.A prospective study was conducted of 27 consecutive black women (of African or Caribbean ethnic origin) and 79 consecutive white women (of European ethnic origin) volunteers attending the antenatal clinic, with uncomplicated singleton pregnancies of at least 34 completed weeks ...

Antenatal Bleeding and Fetal Heart Rate
Gynecologic and Obstetric Investigation, 2010Objective of the paper was to determine the fetal heart rate (FHR) changes that occur in preterm fetuses whose mothers have suffered antepartum bleeding, versus uncomplicated controls. Over a 12-year span, 91 patients with significant antenatal bleeding (bleeding requiring inhospital observation) were examined and compared to 75 controls with ...

Heart Rate Patterns in Fetal Anemia
Fetal Diagnosis and Therapy, 1988Fetal heart rate (FHR) was monitored immediately before cordocentesis on 105 occasions in 49 red cell-isoimmunized patients at 27–37 weeks of gestation. The fetal hemoglobin concentration, oxygen tension and oxygen content were measured and the values related to the FHR patterns, which were classified as reactive, non-reactive, decelerative (isolated ...

Intrapartum auscultation of the fetal heart rate
American Journal of Obstetrics and Gynecology, 1993A fetal heart rate recording containing a variable deceleration was played for 120 physicians and nurses. Although mean estimates for baseline and nadir of the fetal heart rate and duration of the deceleration were not significantly different from the actual values, individual estimates of the three parameters were widely distributed.

Autonomic control of fetal heart rate
American Journal of Obstetrics and Gynecology, 1969Abstract The role of sympathetic and parasympathetic nerves in the control of fetal heart rate was elucidated by using the sympathetic blocking drug, propranolol, and the parasympathetic blocking drug, atropine. The sinoatrial node of the fetal heart is stimulated by parasympathetic drive comparable to the neonate and young adult.

On Electronic Fetal Heart Rate Monitoring
Journal of Obstetric, Gynecologic & Neonatal Nursing, 2011Management of fetal heart rate (FHR) patterns is rapidly changing following the 2008 consensus guideline from the National Institutes of Health and Child Development (NICHD) and a 2010 Practice Bulletin from the American College of Obstetricians and Gynecologists (ACOG).

Fetal heart rate in early pregnancy
Early Human Development, 1990Heart rates were measured by transvaginal sonography twice weekly in ten first trimester fetuses in women who conceived after in-vitro fertilization (IVF) or zygote intra-fallopian transfer (ZIFT). From week 6 to week 9 of menstrual age a rapid increase of the mean heart rate was observed from 113 to 167 beats per min, followed by a slow decrease to ...

Antepartum fetal heart rate monitoring. III. Fetal movements and accelerations in fetal heart rate.
European journal of obstetrics, gynecology, and reproductive biology, 1981This third part of the paper deals with the study of the relationships between fetal movements, fetal heart rate accelerations associated with such movements, fetal heart rate instability and neonatal outcome. No correlations has been found between absence of fetal movements and neonatal distress.
