It could be the effect of the fillers/binders in the levothyroxine. I too had severe palpitations and visits to A&E and always 'nothing is found'. My heart would speed up at any time anywhere without warning. Until I was given Eltroxin (Brand name) and 10mcg T3 added. Eltroxin, unfortunately, isn't being made in the UK now so we cannot get it. Even though the makers said the generic is exactly the same as Eltroxin, I and many others disagree.

If they give you a trial of T3 alone for, say, three months to see if that stops the palpitations. It calmed mine right down.


Hi With any cardiac problems it is considered vital to also be under a good Endo.

A.F not too serious but needs identifying and treating, the 24 hour monitor will show this.

I have had a very similar experience. Have you had your iron & b12 levels checked recently? Mine suddenly took a dive. I ended up in A & E, but they had no idea what was going on. Thanks to this site I kept pushing till I got answers. Since having b12 jabs & iron supplements I feel much better. Hope you will too soon.
