Abstract

Brugada syndrome is characterized by sudden cardiac death associated with ventricular tachyarrhythmia in patients without structural heart disease. We recently observed a case of concealed Brugada ECG pattern, which appeared after oral propafenone administration for atrial fibrillation. A 34-year-old male patient who experienced syncope was admitted to the emergency department with acute atrial fibrillation (AF). Three hundred milligrams of propafenone that were administered to convert AF to sinus rhythm unmasked the Brugada ECG pattern that had remained concealed. The patient showed a type 1 Brugada ECG pattern after taking propafenone.
