Thyroid

[NOCOLA]

I have had a goiter for several years and no problems . However recently I developed A Fib after several years suffering from paplitations. I was initially given amiodrone for the AF for approximately 4 weeks (both intervenously and the 50mg tabs twice daily. Following these meds were changed to MInax which worked reasonably well for a few weeks. Then 3 weeks ago I went back into AF and the hospital did a blood test for the thyroid, although throughout all this process my GP had tested and stated my thyroid was fine. The hospital test revealed a TSH of 0.03 and suggested I return to the GP who again tested and now states I have T level of 26.
I feel anxious and unwell, not sure which comes first if I have an overactive thyroid, is it causing AF or could the AF and amiodrone have caused the thyroid? I have another appointment with the GP but feel confused. Any feedback appreciated.

Thank you for the feedback. I would like to think once the thyroid issue is treated the Af would improve.
My GP is loath to share informations I hope he will understand

An overactive thyroid can cause dysrhythmias of the heart such as AF.  I'm a nurse who usually works in the ICU and cardiac floors and have not heard of Amiodorone affecting the thyroid.  I would question why your thyroid is overactive like your pituatary gland or such.  Ask your GP what your past levels have been and go from there.
