If Long QT syndrome or Brugada detected on ECG/Echo as a result of Flecainide use, does this revert to normal if medication is discontinued?

EKG and Flecanide. Flecanide will not cause Long QT but may manifest Brugada like EKG. Brugada EKG is Dynamic. i.e not present all the times but certain drugs like Flecanide may manifest it. It is true: removing the drug will correct the EKG, but in individuals who had Brugada like EKG on Flecanide and who are symptomatic with loss of consciousness etc. further testing for risk assessment is needed.
