Dynamic ECG Changes in Brugada Syndrome. We present a patient with Brugada syndrome in whom 12‐lead ECXis were recorded just before and after an episode of ventricular fibrillation (VF). A progressive elevation of both the RS‐T segment and J waves just preceding and following the VF, and a close relationship between the amplitude of the RS‐T segment and the preceding R‐R intervals during atrial fibrillation, were documented. These findings support the hypothesis that RS‐T elevation and a subsequent VF are related to a transient outward current‐mediated spike‐and‐dome morphology of the epicardial action potential.
