palpitations and rapid heart beat with hypothyroid?

hi, my tsh is low normal and my t4 is very low at .54 - i have been getting sudden onsets of a rapid heart beat and lots of palpitations - i am not hashis or graves, endo is still trying to figure out why i am hypo at all..... i am on synthroid 50mcg. these symptoms are not any worse than before i started the medicine so thats not it...i am wondering if anyone else has had these rapid heart rates and palpitations with hypo? also i get really crabby all of a sudden when i get this,  my heart checks out fine at the cardiologist and endo says hypo dont cause heart palps ...

Goodness...I thought I was going nutts!  I ended up in the ER after having numbness and tingling on my left side, then heart palpitations that even scared the ER doctor for a few seconds.  I was admitted and ran through a bunch of tests EKG's, MRI's, blood tests, the works, yet they could not find anything wrong with me.  Then later I was told that my TSH levels were low and I needed to ups my meds from .02mcg's to .05mcgs.  Was also given Metoprolol Tartrate to control the palpitations.  Even though I've stopped taking the Metaprolol, I feel better, but was never told that lack of meds could cause these reactions.  I do feel a little strange at times; maybe I'm being a little paranoid, but for the most part, ok.  Thank you for your reassuring post.

Read the book "Solved - The Riddle of Illness" by Stephen E. Langer, MD and James F. Scheer.  Amazon sells it.  The light will shine by helping you understand what you have been going through and what could happen if you don't get help.  You will learn a great deal and realize you can have a fantastic life again.  I gave up on traditional western medical practitioners and decided to try a naturopathic doctor, Dr. Bradley West in Los Gatos & Santa Cruz.  What a relief!  I wish I would have made this move sooner.  I highly recommend him, especially if you suffer from intolerance to cold environments, have cold hands and feet, constipation, dry skin, irritability/mood swings, depression, lagging sexual drive, etc.  All of these things are tied into our hormone balance which we generally know very little about.  Traditional doctors only look at T3, which is ridiculous because all the hormones, antibodies, etc need to be evaluated together. You need the big picture to fix a problem. Good luck with your journey in finding the right balance for your body. Be comfortable again!

i'm sooo tired of the heart palpitations.  they pretty much only occur between the hours of 4 am - 6 am -- after that i can sleep for 8 hours or more with no problem.

i still think the dosage on the levothyroxine is too high.  will be calling back the doctor's office on monday.  grrrr -- getting tired of this.

the palpitations began when i was on the nature-throid a few months ago -- turned out i am allergic to pork, so went off of them and my tsh came down rapidly but new doctor put me on levothyroxine and now the palpitations are back with a vengeneance.

It sounds like your meds are not properly adjusted for you.  It might be a good idea to start a new thread so that members can address your individual concerns.  Just go to the top of the page and hit the orange "Post a Question" button.  

Please tell us a little more about yourself...post labs and ranges if you have them, list meds and dosage, tell us your symptoms.  Granted, thyroid treatment leaves a lot to be desired, but there are many of us who have managed to make the system work for us.  Perhaps we can give you some helpful hints.
