title: Syncope and intermittent Brugada ECG pattern.
abstract: Brugada syndrome is a rare syndrome, with an estimated prevalence in Europe of 1-5/10 000 population, whose initial clinical presentation can be sudden death. Although it has a characteristic electrocardiographic pattern, this can be intermittent. The authors present the case of a 32-year-old man, with no family history of syncope or sudden death, who went to the emergency department for syncope without prodromes. The initial electrocardiogram (ECG) in sinus rhythm documented an isolated and non-specific ST-segment elevation in V2. During further diagnostic studies, a repeat ECG revealed type 1 Brugada pattern. This pattern was later seen in a more marked form during a respiratory infection. The patient subsequently underwent electrophysiological study, followed by implantation of an implantable cardioverter-defibrillator (ICD), with an episode of ventricular fibrillation converted via ICD shock two months after implantation.
