, Would you expect the baseline FHR of a preterm fetus at 28 weeks
gestation to be higher or lower FHR than a term fetus. - 🧠 ANSWER
✔✔Higher. This is related to maturity of the central and autonomic nervous
systems and cardiovascular systems. The sympathetic nervous system,
which increases heart rate, matures before the parasympathetic system
which slows heart rate. As the fetus matures, the baseline heart rate will
decrease and the heart rate variability will increase.
