A 69-year-old white woman presented at our emergency room with right-side pleuritic chest pain, fever, and tachycardia. Results of the physical examination, routine laboratory tests, and chest radiography were unexceptional. An electrocardiogram showed ST elevation in leads V(1) through V(3) with T-wave inversion. Because of the chest pain and the ST elevation, the patient underwent emergency cardiac catheterization, which showed no coronary artery stenosis. A computed tomographic scan of the chest showed pulmonary infiltration in the right middle lobe and the lingula of the left upper lobe; pneumonia was diagnosed, and appropriate antibiotic therapy was started. The electrocardiographic changes met the criteria for type-1 Brugada pattern. Brugada syndrome is an arrhythmogenic disease caused in part by mutations in the cardiac sodium channel gene SCN5A. When the sodium current is disrupted, the outward transient current at the end of phase 1 of the action potential becomes unopposed. This creates a voltage gradient between the epicardium and endocardium, especially in the right ventricular wall, which leads to J-point elevation in leads V(1) through V(3). Fever exaggerates this defect in sodium channels. In our patient, the pleuritic chest pain was caused by the pneumonia, and the ST elevation was probably related to Brugada syndrome, unmasked by the febrile episode. Brugada syndrome can be associated with ventricular tachycardia or fibrillation; the only treatment proven to prevent sudden death is placement of an implantable cardioverter defibrillator, which is recommended in symptomatic patients or in those with ventricular tachycardia induced during electrophysiologic studies.
