Influence of circumferential pulmonary vein isolation for atrial fibrillation on ST elevation in patient with Brugada syndrome.
We present a patient with Brugada syndrome and paroxysmal atrial fibrillation who underwent circumferential pulmonary vein isolation. His electrocardiogram showed normal sinus rhythm and first-degree AV block (P-R 280 ms) with coved-type ST elevation in V1-2 (+2.0 mm) before ablation. During ablation around the left pulmonary vein ostium, atrial fibrillation, progression of ST elevation (+4.5 mm), and T wave alternans occurred. After right pulmonary vein encirclement was complete, ST elevation improved to +1.0 mm. The following day, the ST segments remained lower than baseline levels.
