Here's a checklist for hypothyroidism symptoms:

My understanding is that medics will say no, and patients yes. Have a look at the Thyroid forum on this site

What are your thyroid results?

100% percent yes. I was taking Amiodarone, and this caused damage to my thryoid, which caused me to suffer 3-4 afib episodes a day and have bouts of 1-2 weeks of afib. As soon as I stopped Amiodarone and started on a cause of thryoid treatment, I noticed the difference. Amiodarone has a known side effect of damage to the thryoid and hyperthyroidism was a known cause of af according to my doctors, so definetly was not wishful thinking.

I don't know if your thyroid is causing your AFIB or not, but here is something I found that does trigger it:

After 9 years of trying different foods and logging EVERYTHING I ate, I found sugar was the culprit. Doctors don't want to hear this - there is no money in telling patients to eat less sugar. Each person has a different sugar threshold - and it changes as you get older, so you need to count every gram of sugar you eat every day (including natural sugars in fruits, etc.). My tolerance level was 190 grams of sugar per day 8 years ago, 85 grams a year and a half ago, and 60 grams today, so AFIB episodes are more frequent and last longer. If you keep your intake of sugar below your threshold level your AFIB will not happen again. It's not the food - it's the sugar (or salt - see below) IN the food that's causing your problems. Try it and you will see - should only take you 3 or 4 months of trial-and-error to find your threshold level. And for the record - ALL sugars are treated the same (honey, refined, agave, natural sugars in fruits, etc.). I successfully triggered AFIB by eating a bunch of plums and peaches one day.

Also, in addition to sugar, if you are dehydrated - this will trigger AFIB as well. It seems (but I have no proof of this) that a little uptick of salt in your blood is being treated the same as an uptick of sugar - both cause AFIB episodes. The root problem is that our bodies are not processing sugar/salt properly and no doctor knows why, but the AFIB seems to be a symptom of this and not the primary problem, but medicine is not advanced enough to know the core reason that causes AFIB at this time. Good luck! - Rick Hyer
