Table 1

Cardiac abnormalities and thyroid function during two episodes of myasthenia gravis crisis.

MG crisis	TSH mcunit/ml	Peak troponin, ng/ml	ECG changes	Echo findings
Episode 1	7.6	0.16	ST elevation V1–V6, Q waves V1–V3	Mid ventricular variant Takotsubo stress cardiomyopathy with reduced ejection fraction (EF) of 25%
Episode 2	0.569	0.32	Deep, symmetric T inversions V1–V6	Mid and apical akinesia, EF 30% consistent with classical apical ballooning type of Takotsubo stress cardiomyopathy
