Interpretation of intrapartum electronic fetal heart rate (FHR) tracings has been hampered by interobserver and intraobserver variability, which historically has been high [].In 2008, the American College of Obstetricians and Gynecologists (ACOG), the Society for Maternal-Fetal Medicine (SMFM), and the United … WebIn the normal fetus, there is an interplay between the sympathetic (acceleration) and parasympathetic (deceleration) nervous systems in the control of heart rate. These systems exert their control via the cerebral cortex, the medulla oblongata, the sympathetic ganglia and the vagus nerve.

WebAug 24, 2024 · Prolonged fetal heart rate deceleration, defined as a visually apparent decrease in the fetal heart rate below baseline by 15 bpm for longer than 2 min but less than 10 min, is an example of a non-reassuring fetal heart rate characteristic, which often occurs in response to physiologic and reversible changes to maternal or fetal status .
Fetal decelerations refer to short-term but clear decreases of the fetal heart rate (FHR) identified during fetal heart monitoring. They are classified into three categories according to their shape and timing related to uterine contractions: early, late, and variable decelerations.

Electronic fetal monitoring is used to … See more The causes of fetal decelerations mainly depend on the types of decelerations. Early decelerations in FHR are caused by compression of the fetus’s head during a uterine contraction. As the uterine muscles get tighter and … See more The main sign of fetal decelerations is the decrease of fetal movements. Fetal movements are a sign of the fetus’s well-being and are typically felt by the mother around the 28th … See more Variable decelerations usually indicate an obstruction to the fetal blood flow through the umbilical cordor compression of the umbilical vessels … See more
