    Why does fetal distress (hypoxia) cause bradycardia and not tachycardia?

    In a non stress test performed in the labor room, fetal bradycardia is a danger sign indicating fetal distress (hypoxia). Why does fetal hypoxia cause bradycardia while hypoxia in adults cause tachycardia? What is the mechanism for both and why is it reverse?
