Fetal heart rate following coelocentesis [PDF]

The Journal of Maternal-Fetal Medicine, 1997
For psychological reasons, coelocentesis was performed in 20 women prior to termination of pregnancy, at 6-11 weeks of gestation. The fetal heart rate (FHR) was measured immediately before the procedure and at 1, 5, and 10 min afterward. There was no significant difference between FHR before coelocentesis compared to the values at 1 min (mean = 158 ...

Fetal heart rate throughout pregnancy [PDF]

American Journal of Obstetrics and Gynecology, 1972
Abstract Serial fetal heart rate (FHR) determinations were made from early pregnancy to term in 24 healthy fetuses by means of an ultrasonic device. A decreasing FHR pattern was noticed from the eleventh through the thirtieth weeks, after which the values remained more stable (about 140 beats per minute) until term.

Fetal heart rate throughout gestation. [PDF]

, 2022
Fetal heart rate was monitored biweekly by ultrasound on high-dose (1x108 PFU ZIKV-DAK) dams to confirm fetal viability. The horizontal, dotted lines on the graph represent the range of normal heart rates for fetuses at WNPRC.

Fetal heart rate tracing interpretation in cases of fetal heart block: A case series

Clinical Case Reports, 2022
Simple assessment of FHR baseline variability can differentiate second‐degree heart block (SHB) from complete heart block (CHB). In cases of SHB, antepartum NST can be reliably used for fetal surveillance.

Non-invasive Fetal Electrocardiography for Intrapartum Cardiotocography

Frontiers in Pediatrics, 2020
Fetal monitoring is important to diagnose complications that can occur during pregnancy. If detected timely, these complications might be resolved before they lead to irreversible damage.

Magnesium sulfate-induced blocked premature atrial contractions resulting in fetal bradyarrhythmia

Journal of Arrhythmia, 2014
Here, we present a rare case of fetal bradyarrhythmia following magnesium sulfate therapy for preterm labor. After we switched treatment from ritodrine hydrochloride to magnesium sulfate at 25 weeks' gestation, the fetal heart rate dropped from 150 bpm ...
