Antepartum fetal heart rate monitoring
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.

Electronic fetal heart monitoring has become widely used during labor. In initial experience with electronic fetal heart monitoring direct methods were used and, specifically, an electrocardiogram electrode was applied directly to the presenting part of the fetus.

A flat decelerative fetal heart rate tracing with normal fetal heart rate variability
American Journal of Obstetrics and Gynecology, 1994We report two cases for which computer interpretation of nonstress test indicated a flat decelerative trace in spite of normal fetal heart rate variability. Fetal behavioral state in the first case and signal loss in the second case were possibly responsible for this computerized interpretation of the tracings in the absence of fetal distress.

Intrapartum fetal heart rate monitoring
American Journal of Obstetrics and Gynecology, 1979A total of 1,996 direct fetal heart rate (FHR) tracings in labor were analyzed using the first and last 30 minutes of monitoring in order to evaluate individual FHR characteristics as to their ability to predict the fetal status. Comparisons were made between individual FHR characteristics occurring alone ("uncomplicated") and those occurring in ...

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.

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 ...
