RESUMO
Brugada syndrome (BS) is an under recognized condition inherited through autosomal dominant transmission that consists mainly of characteristic electrocardiogram findings with ST segment elevation, in leads V1 through V3, complemented with right bundle-branch block pattern. Patients usually have medical history of prior syncopal episodes and are at risk of sudden cardiac death; although diagnostic studies reveal structurally normal heart. Adequate treatment consists of implantable cardioverter defibrillator which can prevent associated lethal arrhythmias that lead to sudden cardiac death. Correct diagnosis with medical history and characteristic electrocardiographic findings is essential to the physician to prevent unnecessary treatments that can further compromise patient's health status.
