Sudden cardiac death due to hypoglycemia.

We present a case of sudden cardiac death from hypoglycemia due to duodenal insulinoma in a previously healthy male. Cerebral neuroglycopenia symptoms were not evident and there was no knowledge of an existing insulinoma. It is suggested that glucose administration be considered in the setting of patients with suspected hyperinsulinemia and hypoglycemia. Rapid recognition and treatment could prevent cardiac irritability and death.
