I have been taking Atenolol for at least 5 years to keep my heart rate under control, it beats too fast. The problem started with no warning, my heart rate was a little over 160 beats per minute. I went to the E.R. and stayed for a couple hours until it was back down to normal. But as soon as I stood up a walked out to my car, it went right back up. I was diagnosed with an underactive thyroid and put on meds for both problems. I saw a cardiologist because of a history of mitral valve prolapse. Testing showed no signs of a prolapse at that time. The doctor said that he didn't know what was causing the fast heart rate. A year ago I saw another cardiologist who did not believe the problem was with the heart. I am thankful that the meds keep my heart rate normal, but I do not want to be on meds for the rest of my life. I ran out of the Atenolol once and was without it for 2 days. The morning of the third day my heart rate was 160, and at times 200 for a short time.

  • Make sure you're being treated with the correct dose of thyroid replacement medication or LT4. Because if you're not, your symptoms will persist and you won't get any better. If you not already seeing an endocrinologist, I'd find one who knows about the current regimen for LT4 and where your TSH should be.And do some research about thyroid yourself and learn as much as you can, so that you can talk to the doctor about your symptoms and what isn't being treated.Current protocol is your weight in kg multiplied by 1.6. And don't use the generic, Levothyroxine, as it varies in potency.
