Which is not true about early after depolarizations in ventricular cardiac muscle? A.Excitatory currents re-activate and interact with other currents which can cause EADs. B.EADs are sustained by re-entrant refractoiness. C.EADs are often associated with Long QT syndrome. D.Premature reactivation of excitatory current currents during repolarization is a cause of EADs. E.Adverse drug reactions resulting in diminished potassium currents relative to calcium currents are associated with EADs.
