Hypothyroidism and Heart Palpitations

Hello Everyone - I am a 34 year old female who was diagnosed about 8 months ago with hypothyroidism.  Additional testing then diagnosed me with Hashimoto's Thyroiditis.  My initial TSH level was 12.7, so I was I placed on 50 mcg of Levothyroxine.  My TSH level is now 4.8.

I have had all of the normal hypothyroid symptoms - weight gain, muscle pain, tiredness, etc., but my biggest complaint (that doesn't fit symptoms of hypo) is heart palpitations.  At their worst, I was having them for sometimes 5 - 6 hours a day.  I did see a cardiologist, who did an EKG, echocardiogram, and also had me a wear an 24-hour heart monitor. After reviewing all of the tests, the cardiologist said that I had a perfectly healthy heart, and that the palpitations were most likely a result of hypothyroidism.

For the first few months after being on the Levothyroxine, I can honestly say that I did NOT feel any better.  However, over the past 6 - 8 weeks, I have begun to feel more like my old self again.  FINALLY, the palpitations started to subside - occurring for only 3 - 4 hours a day, then about 1 hour a day, then only a few flutters here and there.  I was absolutely elated to have them gone!

Within the past week however, as soon as I woke up in the morning, I could tell I just didn't feel right.  I've been having more palpitations again (an episode last night lasted for about 2 hours).  It's only been a few days since the  palpitations have returned, but I am scared to death that I am going to have to start dealing with them again.  They make me feel awful!

I promised myself I was going to keep this as concise as possible, and looking at the above I appear to have failed.  Has anyone else been diagnosed with Hashimoto's or hypothyroidism and suffering from long episodes of heart palpitations?  Any help or advice would be greatly appreciated!

I was on a beta blocker for about four years but it was lowering my blood pressure too much.I wanted to get off of it.The last cardiologist visit I was told they dont use beta blockers for hypothyroid anymore.I have never been to an endochronologist.I would like to go because recently I have been waking up feeling my heart beating.Its scary.They tell me there is nothing wrong with my heart.

Please post your thyroid related test results and reference ranges shown on the lab report so that members can better assess the adequacy of your testing and treatment.  Do you have any other symptoms?  Are you taking thyroid med?  If so, what type and what dosage?

I have low T3 and TSH sometimes and palpitations.  I think thyroid glandulars may help like natural sources.

About 2 years ago, I was told that I had a TSH of 8. The doctor informed me that I was borderline and that I could take meds for it or not. I didn't know much about the thyroid at the time so I opted out. And also I prefer homeopathic remedies. Recently I had another test and my TSH was 6 (I can't recall the number following the decimal). After some of the comments and research I have done on the thyroid, why would my doctor
discount this medical issue?? Any suggestions... Also, anyone heard of thyroidinum...

definitely see your endocrinologist.  tach could have to do with thyroid. also consider shortness of breath etc. to be a little bit of anxiety. when you feel that way try to stay calm and breathe steady. in through the nose out through the mouth and think about something calming clearing your mind of the stress of all the thyroid concerns. it is not easy but it does help. I had thyroid cancer so believe me i understand what a pain it is trying to get the numbers under control and concentrate on everything else..best thing to do is let your doc know about tach too.  good luck with all.
