Key result
In fetal sheep at 0.85 gestation, mean fetal heart rate in low-voltage sleep was 159 beats/min after sympathectomy compared to 173 beats/min in control fetuses.

The authors reiterate that high-frequency spectral power of fetal heart rate variability is minimal in the last third of gestation in fetal sheep and is largely unaffected by autonomic blockade.
Absolute Event Rate: 159% vs 173%

Koome et al. (2014) conducted a letter in Fetal heart rate variability. Sympathectomy and parasympathetic blockade vs. Control fetuses was evaluated on Mean fetal heart rate (FHR) at 0.85 gestation in low-voltage sleep. In fetal sheep at 0.85 gestation, mean fetal heart rate in low-voltage sleep was 159 beats/min after sympathectomy compared to 173 beats/min in control fetuses.
