EKG Pattern of Brugada Syndrome and Sudden Infant Death Syndrome—Is It Time to Review the Diagnostic Criteria? Case Report and Review of Literature

Brugada Syndrome (BrS) is a cardiac disorder characterized by incomplete right bundle‐branch block and ST elevations in the anterior precordial leads especially V1–V3, associated with an increased risk for sudden cardiac death (SCD) in young adults. Our case describes a patient with family history of sudden infant death syndrome (SIDS) who presented with a Brugada pattern unmasked by severe hyperkalemia and diabetic ketoacidosis. Several studies have concluded there may be a genetic link among SIDS, SDC, and BrS resulting from mutations in cardiac ion channel‐related genes. Recognizing SIDS as part of the diagnostic criteria for BrS would help us identifying a significant number of families susceptible to develop SCD (as well as SIDS).
