A. Representative electrogram recordings from Ctrl and MI/iAL preparations during normokalemia and hypokalemia. Arterially-perfused wedges from MI/iAL but not Ctrl animals were prone to VT/VF during challenge with rapid pacing under conditions of hypokalemia. B. Incidence of VT/VF in Ctrl (n=7), MI (n=5), and MI/iAL (n=7) during hypokalemia.
