Hypoglycemia And Supraventricular Tachycardia In An Infant Of Diabetic Mother: A Possible Association.

3 to 10 % of all pregnancies are associated with some degree of glucose dysregulation. 90% of those are related to gestational diabetes. Infant born to diabetic mothers with poor glycemic control, have greater associated morbidity and mortality. Hypoglycemia is the common manifestation in such infants, with an incidence of up to 50 % in the immediate postnatal period 2, Atrioventricular block has been documented in infants of diabetic mother (IDM). 4 Reactive hypoglycemia has been reported to trigger atrioventricular nodal reentry tachycardia in an adult. We describe a macrosomic IDM, who developed severe hypoglycemia and simultaneous supraventricular tachycardia (SVT) in the immediate postnatal period, suggesting a possible association and biological plausibility. Sinus rhythm was established with adenosine and after institution of stable euglycemia.
