Abstract excerpt

BACKGROUND: Two principal mechanisms are thought to be responsible for Brugada syndrome (BS): (1) right ventricular (RV) conduction delay and (2) RV subepicardial action potential shortening. This in vivo high-density mapping study evaluated the conduction and repolarization properties of the RV in BS subjects. METHODS AND RESULTS: A noncontact mapping array was positioned in the RV of 18 BS patients and 20...
