Hypoglycemia and supraventricular tachycardia in infant of diabetic mother- A possible association

3 to 10 % of all pregnancies are complicated by diabetes, 90% of which is contributed by gestational diabetes. Infants born to diabetic mothers with poor glycemic control are associated with high morbidity and mortality. Hypoglycemia is the common manifestation in such infants, with an incidence of 30-40 % in the immediate postnatal period 1,2 . About 10 % of infants of diabetic mothers show evidence of cardiac dysfunction, Atrioventricular block has been documented in infants of diabetic mothers (IDM) 3 .Reactive hypoglycemia has been reported to trigger atrioventricular nodal reentry tachycardia in an adult 4 . We describe a macrosomic IDM with severe hypoglycemia presenting with supraventricular tachycardia (SVT) in the immediate postnatal period, suggesting a possible association.
