thyroid/palpitation connection

[littletot]

Diagnosed w/Hashimoto 20 yrs ago. Have palpitations (usually pauses not fast beats) since. Been told no concern. But some days they are frequent then weeks with little occurence. Am I in danger of stroke or heart attack?  No fainting, dizziness or short breath symptoms. Female, 68 yrs old. No major stresses in my life. Try to avoid caffine.

Would make sure you are not on too much thyroid medication -- excessive thyroid hormone (from the thyroid itself or from medications) can cause heart palpitations and possibly atrial fibrillation which increases the risk of stroke.  You need to look at your TSH level to make sure it is in the normal range.  A cardiology evaluation may also be appropriate to make sure there is not a problem with the heart as it may have nothing to do with your history of thyroid disease.

Yes, I had nuclear test, Heart Monitor for 24 hrs. and angiogram 4 years ago.  Said everything looked fine.  Since then I have had tsh, lipids, and electrocardiogram yearly.  should I have a cardiologist exam again?
