Thyroid Levels

[NMAC12]

I have recently suffered AFib episodes (up to 205bpm). At the time I was given amiodorone for approximately 4 weeks, 4 months later my thyroid appears to be a problem TSH is 0.03 and T4  is 26.
Can anyone comment if the thyroid could cause AF to the above level. I also recently had a nucla scan for nodules, no results as yet. I also wonder which, either AF or Thyroid causes a feeling of head rush constricted throat in the glands and sometimes feel like I swallow over a smooth swelling in throat although I can eat okay, no obvious signs of swelling on my neck. I take Solatol.

Feedback appreciated

I definitely agree the anxiety stems from 1) all the crazy symptoms we (thyroid patients) have to deal with, and 2) heart arrythmias are anxiety-provoking in and of themselves.

I agree with Smilerdeb - it appears you're hyper with very low TSH and high FT4.  High T3 and T4 levels and increases in T3 and T4 meds can surely cause arrhythmias.

If you have more than one set of labs going back a bit and can get ahold of those, it would be interesting to see how TSH, FT3 and FT4 have changed relative to your AFib.

Good luck with your appointment.

Going by what I have read, I would say Hyperthyroidism is causing your A-fib.
I had A-Fib 3 times in 2 weeks before RAI & TT (I have Graves Disease and had Hyperthyroidism.
The 3rd time I had A-Fib , it had to be shocked back into Rythm.
The number '26' is most probably your FT4 although I cant really be sure as you dont know, but sounds like it.
The 2 names of the heart rates are Bradycardia and Tachycardia which is an irregular heart beat.
I was on Inderal (beta Blocker) for a long time due to Supraventricular Fibbrilations and Atrial Fibrillations.
I was also born with a heart murmur so had that to deal with too.
Since RAI and TT (june 2008) I have slowly got back on track and am now back in fulltime work as Medical Admin and PCA and studying Acute Dementia online distance course.
Prior to RAI, I thought I would never work again........I was wrong.
Get your results each time you get your bloods done and keep a journal of all symptoms then you will slowly see a pattern.
if you are Hyperthyroid, you should be on anti-thyroid meds until you know what course of action your Doctor wants you to take.
Good Luck :)

Hello

Hope your day has improved, appreciate your response, the first time I had AF, my heart was irregular 205BPM for over an hour, then again that evening. Apparently there was two types of rthythm? not sure what this means.
Recently I had AF again but it regulated itself, where before I was given amiodorone. As far as the Thyrois result go, GP has regularly had full blood tests done states all is fine and quite normal for me to have T low or I may be fighting some infection etc . The only info I have is TSH was 0.03 and Gp states my recent thyroid test reveals 26 which is higher then the normal 12 - 19. I have an appoitment to gain info about nuclar scan test today, will ask more questions. Yes anxiety plays a part but I believe it to be result of other symtoms.

Kind regards

Well, it's not easy, and you caught me on a bad day, so I might have to say that at the moment I'm not managing it!

My SVT is due to a congenital heart defect, so I've had it and been dealing with it all my life.  It's probably not as scary to me since I'm so used to it.  However, it never stops being a major annoyance.  I think one of the best things you can do (easier said than done) is relax.  I also have a maneuver that my electrophysiologit recommended that I do that usually stops the SVT within seconds (if I'm at home and lie down in a quiet place for a minute or two).  Once you know that you've been there, done that, and have the T-shirt, it gets a little easier, but not less annoying.  When you have AFib, is your heartbeat also irregular, or just fast?

I'm hypo, and every time I up my dose of levo, the SVT gets out of control.  Unfortunately, my TSH is still too high and T3 and T4 barely low normal.  So, I have a way to go to be "normal".

I don't know about the Solatol masking the AFib.  I'm on atenolol, which is just a bet-blocker.  It seems to me the Solatol should either control the symptoms or not, but not just cover anything up.  When did the throat constriction start?  Do you feel like it could be from anxiety?  Did you have any thyroid testing when your AFib first started, or just recently?  Do you have free T3 and free T4 results?  Do you have a reference range on the T4 you posted above?  What are your other symptoms?

Whew...lots of questions.

Thanks

At the time I feel my throat constrict it does not feel like I am in AF, unless the Solatol is masking things. How do you manage SVT and anxiety. I am new to this condition and feel very anxious.

Being hyperthyroid, which seems to be the case with you, or medication for hypothyroidism can both cause arrhythmias.  I get SVT, and my HR goes above 200 regularly.  My SVT gives me kind of a "tension" in the neck and shoulders, which goes away immediately when the HR goes back to normal.
