Acute pericarditis can unmask true Brugada-type ST-segment elevation in patients with asymptomatic Brugada syndrome.
Pericarditis-related ST changes may warrant Brugada evaluation; this case report leaves open its incidence and clinical relevance.
A 26-year-old man was admitted to our hospital because of acute pericarditis. The current patient had a saddle-back type ST-segment elevation shortly after the onset of acute pericarditis. Interestingly, it converted into a coved type ST-segment elevation, subsequently regressed gradually as acute inflammation improved. After 3 months, right ventricular rapid pacing induced ventricular fibrillation, and intravenous sodium channel blocker induced a coved type ST-segment elevation. The current case implies that a Brugada-type ST-segment elevation, which is thought to be false in acute pericarditis, may be true in some patients with asymptomatic Brugada syndrome.
