Have you eliminated AFIB by normalizing thyroid hormones?

Has anyone eliminated their AFIB by bringing their thyroid levels to the normal range. I was diagnosed with sub-clinical hyperthyroidism and Graves when my AFIB was discovered. Methimazole brought my TSH level to normal, and I went from being in AFIB 100 percent of the time to under 20 percent of the time. I'm considering an ablation, but I want to make sure I've reached the maximum effectiveness through the thyroid medication first.

I don't have Afib but have been having heartbeat issues. When I stand my heart "races" and I am also often lightheaded and dizzy. I believe that is due an overdose of the synthetic thyroid hormone, levothyroxine. I have been on a full replacement dose after treatment for Graves disease forty years ago. My "heart" symptoms started about 2 years ago. Again I believe that this due to an overdose of levothyroxine. My challenge on this is that my serum TSH is in the "normal" range. Thus my primary care physician is reluctant to make a change. Any recommendations on what else to test for? Perhaps a change in the source of the medication? I am currently using the generic from PUBLIX. Prior to this I used Synthroid.

do they test your T3 and T4 and are they in the normal range?
