Whilst reading through some information from another thyroid site came across this, a very interesting piece

Thyroid hormones and atrial fibrillation

I worry about my ft3 being lower in range since starting levo, as my mum had AFib, and did not get on with the warfarin they gave her, never had a thyroid test as far as I know so no idea what her levels where.

Oh dear it is a worry! Each of us is different. My doctor was running the fear by me re suppressed TSH & risk of AF & osteoporosis (which I have from levothyroxine) my heart I think is fine had ECGs done in past. Just thought this piece(fair enough Canadian )was very progressive & identifies the need to look at T4 & T3 again depends on individual. I hope you get sorted soon, this gets read widely in medical sector.🤞

Thanks for posting this, the Canadian site is always very good and this is very interesting and informative indeed! I have palpitations and had my heart checked a few years ago for the second time but they don't find a great deal - some atrial tachycardia - but I am also at risk of heart disease from having high calcium (hyperparathyroidism recently diagnosed). I have recently compiled my results from several years and my T3 is too low, on the few occasions they've measured it and I need T4 to be high in range which makes TSH v low indeed. I feel threatened by my GP tbh with osteoporosis and heart problems whilst they've ignored my high calcium for 4 years which is causing me more health issues. This just proves to me that the research is all important but it's unlikely a gp will read it. I need to sort my T3 out myself though going privately is expensive 🫤

Good luck on your journey, & I'm glad this has opened up another area to discuss hopefully you'll get refered to an endo? Thyroid UK you can access info re endocrinologist hopefully in your area that's progressive. Must be an awful worry for you & I've never heard of high calcium being a problem but I'm still learning.

[Maztee in reply to Humphre]

Thanks, I've seen endos. They ignore it as I'm within range and also warn me about high T4, low TSH however they don't suggest anything else! I asked for T3 and was told they don't prescribe it at that hospital!!! Just gathering my energy to progress but can't currently afford a private endo though there is one locally and wondering why I can't just do it myself!

[Humphre in reply to Maztee]

This is a reacurring problem methinks to each his own battle🤞

Gosh this is interesting, I am not long out of hospital having had AF. My TSH has been low for a few years, T4 always within range, but never had T3 measured at GPs, I think the labs only do if there’s a problem with the T 4?. I asked the hospital to check thyroid whilst in and now have sub clinical hyperthyroidism. Because I had to go on amiorodine I am on a low dose on carbimazole for the moment and under endocrinology. But they say they will never know if it is the thyroid that caused the AF…….mmm this article has now refuelled my fears that it has. My GP ignored the low TSH for years, I wonder if they should now be taking a bit more note of figures?. I watch with interest to see what research follows this study, if GPs can identify patients at high risk of AF then there is room for improved prevention.

[Humphre in reply to Torquaygirl]

I'm finding new things out as I research my own problems, I've paid for my own blood tests as they include T3, my GP doesn't like that as he doesn't know the labs used🤦if NHS would do T3 as routine along the T4 & get them in balance would be more helpful. I'm now saving up to do the Di02 gene test to see if applies to me but I've a blood test on Monday 🤞 levels will have improved. I'd certainly continue to research your own health one day GPs & research will connect.

The hospital have done a recent T3 which was 3.6 now I am under endocrinology. I am back seeing them in 8 weeks. Thanks
