Sympathetic nerve innervation would result in an increase in fetal heart rate. The release of epinephrine as a result of sympathetic innervation would lead to an increase in fetal heart rate. The release of norepinephrine as a result of sympathetic innervation would lead to an increase in fetal heart rate. Stimulation of the vagus nerve would indicate parasympathetic innervation and result in a decreased heart rate.
