Risk calculators and risk factors for Myasthenia gravis electrocardiogram

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

Overview

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]
