Abstract:
We report a 44-year-old male who was admitted for Influenza B and fever, presenting a type I Brugada pattern on the electrocardiogram. He evolved without cardiovascular symptoms. The pharmacological test with intravenous Procainamide reproduced type I Brugada pattern and the programmed electrical stimulation was negative for ventricular arrhythmias. He was discharged without incidents. Clinical aspects of Brugada syndrome and the importance of fever are discussed in the current context of the COVID-19 pandemic.
