Reporte de un caso de fibrilación auricular como manifestación inicial de síndrome de Brugada

Brugada syndrome (BS) is an arrhythmogenic condition characterised by an electrocardiographic pattern where there is an elevation of the ST segment in leads V1 to V3, and a right bundle branch block. It is an uncommon condition in our environment, being more prevalent in other areas such as Japan and southwest Asia. Its aetiology is multifactorial and is still under discussion. Differential diagnoses cover acute coronary syndrome, right bundle branch block and pericarditis. We describe a case with a typical electrocardiographic pattern manifesting with syncope and atrial fibrillation.
