The mechanism underlying the RBBB and ST-segment elevation in right precordial leads in patients with the Brugada syndrome is thought to be an outward shift of the ionic currents during early repolarization causing a marked accentuation of the action potential notch in right ventricular epicardial but not endocardial cells. The outward shift of current ultimately leads to loss of the action potential dome causing marked abbreviation of the action potential in the right ventricular epicardial cells.3, 4, date: 2003-07 date_type: published publication: Indian Pacing and Electrophysiology Journal volume: 3 number: 3 publisher: Indian Pacing and Electrophysiology Group pagerange: 91-92 refereed: TRUE referencetext: 1.
