In the high-risk group, the average fetal heart rate was greater and decreased over gestation from 148 to 140bpm, regardless of outcome. In the low-risk group, it decreased from 145 to 138bpm. In high- and low-risk groups, the average number of heart rate accelerations ≥15bpm increased...
Muturation of body and breathing movements in 24～33 week-old fetuses threatening to deliver prematurely[J].Early Human Development 1999,55(01).Kisilevsky BS, Hains SMJ, Low JA. Maturation of fetal heart rate and body movement in 24 to 33 week-old fetuses threatening to deliver prematurely....
but range up to 30mgkg−1day−1. The concern about this level of exposure in neonates was addressed in part by a study of neonatal male rats treated for 3 weeks with either intravenous or oral DEHP. The intravenous doses were 60, 300, and 600mgkg−1day−1, and the oral dos...
Internal fetal monitoring (IFM) is sometimes used when a pattern of non-reassuring fetal heart tones has been detected during labor. This can include a non-reactive pattern in which the baby's heart rate drops during contractions, which is a normal occurrence and is expected, but then fail t...
A fetal heart rate is between 110 and 160 beats per minute and can vary by five to 25 beats per minute. Your baby’s heart rate can change based on conditions in your uterus. If the heartbeat is outside of the range, it could mean that your baby isn’t getting enough oxygen or ha...

Intrafetal variance was on average 40 – 80% of the total range of the four movement parameters. Normal reference ranges were developed for incidence parameters of fetal body movements from 24 wk of gestation onward. The overall decline in the incidence of movements during pregnancy appeared to ...
Two stages of the human heart are integrated Seven healthy fetal hearts between the gestational ages of week 8 and 12 were dissected, taking the base and apex from six donors and the apex attached to peeled epicardium from one (Fig.1a). These 13 fetal samples were dissociated, sequenced and...
When the pulmonary andsystemic circulationsare in a series, as in a normal adult heart, cardiac output can be quantitatively described by either the left or the right ventricular output. Because the fetus has a parallelcirculatory system, fetal cardiac output is measured and reported as the sum ...
1g). Overall, most clusters were distinct; however, one cluster appeared to bridge between multiple other cell types and expressed an ambiguous range of developmental markers. This cluster was composed mostly of fetal cells, which suggests that these were largely unspecified immature cells (Fig. 1h...
