MG itself can be bad enough that it affects the heart.

Other things that can are endocrine issues. Have you been fully evaluated in that area? And I don't mean only thyroid and blood sugar.

Are you having any other symptoms?

Wait until the thymus scan and see what your neuro says.

Has anyone tested you for a blood clot? Some people who have IVIG can get one. Just a thought, don't panic!

Did you get the records of your heart scan? I recommend reading them.

Are you sure they checked for pulmonary hypertension?

What's your blood pressure like?

I'm not sure what to think. Maybe your MG is just bad right now.

Don't forget that things change over time and it's been three years since the last cardio check. You might want to see one again and ask about an echocardiogram (ultrasound).

I hope you get it all figured out!!!
