It would be helpful to know if you convert your T4 to T3 well? T3 is very needed by our cells muscles and more . The heart is a muscle and has a large receptor sights for T3. You might want to try another brand of T3 that agrees with you. I am sharing my own experiences. I had to switch my T4 brand to my current one that I dose with . The previous brand caused me palpitations and all sorts of symptoms. The same can be with T3 brands. For me Lactose, acacia, manitol, talc causes problems. I hope this helps.
You would have to run labs with both FT3 and FT4. That will be very telling. If your FT 3 comes back low and your FT4 comparatively higher than you know you are not a good converter. If you are on T3 now don't change anything and test just the way you are dosing now assuming you are at least 6 weeks on the same dose with both T3 and T4 dose. Wishing you fast resolutions.
