Overview
There is controversy about ECG changes in MG. 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. These abnormalities include arrhythmias (which can increase the risk of sudden cardiac death, Q-T prolongation, conduction disturbances and ST-T changes.
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]
