Sudden cardiac death due to hypoglycemia
The American Journal of Emergency Medicine
|July 1, 1983
Summary
Sudden cardiac death occurred in a healthy male due to hypoglycemia from an undiagnosed duodenal insulinoma. Prompt glucose administration is crucial for suspected hyperinsulinemia to prevent fatal cardiac events.
Area of Science:
- Endocrinology
- Cardiology
- Pathology
Background:
- Hypoglycemia can lead to severe cardiac complications.
- Insulinomas, particularly duodenal insulinomas, are rare pancreatic tumors.
- Undiagnosed insulinomas can present with severe, life-threatening hypoglycemia.
Observation:
- A previously healthy male experienced sudden cardiac death.
- The cause was identified as severe hypoglycemia.
- The hypoglycemia was attributed to an undiagnosed insulinoma located in the duodenum.
- Notably, the patient exhibited no overt signs of cerebral neuroglycopenia.
Findings:
- Undiagnosed duodenal insulinoma can lead to fatal hypoglycemia.
- The absence of typical neuroglycopenic symptoms can mask the severity of hypoglycemia.
- Hypoglycemia can precipitate cardiac irritability and potentially lead to sudden cardiac death.
Implications:
- Glucose administration should be considered in patients presenting with unexplained hypoglycemia and suspected hyperinsulinemia.
- Early recognition and management of hyperinsulinemic hypoglycemia are vital to prevent life-threatening cardiac events.
- This case highlights the importance of considering rare causes of hypoglycemia, even in the absence of classic symptoms.
