Fetal bradycardia resulting from maternal hypoglycemia. A report of two cases.
Two term-pregnant women presented in the obstetric unit with marked diaphoresis and tremulousness. Fetal heart rate monitoring revealed severe bradycardia. Both mothers had blood glucose levels consistent with the diagnosis of hypoglycemia. In both cases the fetal heart rate normalized with improvement in the mothers' glycemic state. The presence of maternal hypoglycemia should always be considered as a potential cause of fetal bradycardia.
