We present a patient with fever-induced Brugada syndrome, a rare cardiac disease caused by an inherited ion channelopathy and associated with malignant arrhythmias. ECG findings normalized after the fever resolved. As Brugada syndrome can be confused with anterior myocardial ischemia, right bundle branch block and intoxication with tricyclic antidepressants, ECG recognition is important. Patients with Brugada syndrome are instructed to avoid contraindicated substances, and fever should be treated aggressively.
