Fever-induced type 1 Brugada pattern.

Brugada syndrome, first described over 20 years ago, is characterized by a typical electrocardiographic pattern with coved-type ST-segment elevation in the right precordial leads and a high risk of sudden death in otherwise healthy young adults. The electrocardiographic pattern is sometimes intermittent, and fever is a possible trigger. The authors present the case of a 68-year-old woman who came to the emergency department with fever and syncope. A diagnosis of community-acquired pneumonia was made. The electrocardiogram performed when the patient had fever revealed a type 1 Brugada pattern, which disappeared after the fever subsided. After other causes of Brugada-like pattern were excluded, Brugada syndrome was diagnosed and a cardioverter-defibrillator was implanted. This case demonstrates that this entity can be diagnosed at more advanced ages and highlights the usefulness of electrocardiography in a febrile state.
