Hypothermia can be caused by magnesium sulfate(a drug often used for preeclampsia), or maternal hypoglycemia(low blood sugar). A complete heart block can be a result of a congenital cardiac anomaly or idiopathic. With a heart block the brain does not communicate with the heart, so it makes the monitoring of the fetal heart rate useless.

Bradycardia-low heart rate
A heart rate below 120 beats per min. is called bradycardia. A heart rate between 90-110, though, could be a normal variant. It is also important to make sure that the bradycardia is the infants heart rate and not the mothers. Causes of bradycardia that are not normal include maternal hypothermia(the mother has a low body temperature), some drugs, or a complete heart block in the infant. Another cause of bradycardia is sever hypoxia (or decreased oxygenation).
