We reported two cases of prolonged fetal bradycardia associated with maternal hypoglycemia. Both pregnancies were complicated with diabetes mellitus type 1 and controlled by increasing doses of insulin. The pregnant courses were uneventful until the 37^th week of pregnancy. Prolonged fetal bradycardia (100-110 bpm) associated with decreased variability and maternal hypoglycemia were noticed in the early morning at 37 weeks and 4 days and 37 weeks and 1 day of pregnancy, in cases 1 and 2, respectively. Baseline fetal heart rate as well as variability returned to normal immediately after the correction of maternal hypoglycemia. In view of impending macrosormia and fetal distress, the patients underwent cesarean section and well-nourished infants were delivered with Apgar scores of 8 and 9 (1min), in cases 1 and 2, respectively. The children are now doing well without any sequelae of fetal bradycardia. A possible contribution of maternal hypothermia during hypoglycemia on the development of fetal bradycardia was discussed.
