The dimension of chaos in the fetal heart rate
American Journal of Obstetrics and Gynecology, 1991Variability in the fetal heart rate is known to be a sign of fetal well-being, and yet the origins of the variations remain unclear. This study incorporated the nonlinear analytic techniques of phase-space reconstruction and dimensional analysis to 12 normal heart rate tracings obtained from fetal scalp electrodes of fetuses in labor.

Electronic fetal heart rate monitoring is a widely utilized means of assessment of fetal status during labor. Whereas little evidence exists regarding efficacy, this modality continues to be used extensively in every modern labor and delivery unit in developed countries.

The relationships between antepartum baseline fetal heart rate, baseline variability, accelerations, decelerations, and fetal movement and intrapartum fetal heart rate, fetal acid-base assessment at delivery, and Apgar scores 1 and 5 minutes after delivery were studied in 290 mature pregnancies.

Numerous studies have shown the clinical usefulness of monitoring fetal heart rate (FHR) variability. Among the disorders associated with decreased FHR variability during labor are fetal asphyxia and acidosis and subsequent distress in the newborn. Among the factors that influence FHR variability are maternal fever, fetal immaturity, so-called fetal ...

Antenatal Bleeding and Fetal Heart Rate
Gynecologic and Obstetric Investigation, 1995Objective 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 ...

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 ...

Fetal heart rate (FHR) monitoring is important because it provides basic patterns that can be correlated to the acid–base status, circulatory volume, and oxygenation status of the fetus through brainstem detection and subsequent cardiac response. It has numerous during the antepartum and intrapartum stages [1].
