Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Electrocardiogram

  • There is controversy about ECG changes in MG.[1] These changes are mostly non specific but the fact that they will regress after treatment of MG will rise this suspicion that MG causes these abnormalities.[2][3]
  • These abnormalities include  arrhythmias (which can increase the risk of sudden cardiac death[4], Q-T prolongation[3], conduction disturbances and ST-T changes.[2][3][5]
