Do you have Hashimotos and tachycardia (fast heart rate)

Hi I posted previously but was told maybe this might work to get a better answer....
I am 26 I had a baby in NOV 06' ever since I have not felt right I started getting palapitations and had an episode of SVT went to the er my tyroid test showed 6.2 which showed HYPO, I dont know the name of all the tests I think that test was a tsh I think thats right but agian not sure...so went back to my regular doc and she rechecked my thyroid free t3 and t4 which the one for HYPO was .1 away from not being with in normal range and she said it was fine.....showing .1 away from having HYPO and then showing HYPO in the ER would indicate to me further testing would need to be done....THEN I started with a high heart rate 24 hours a day not episodes but when sitting it is around 100+ and then when my feet hit the floor can go as high as 180 depending on what im doing, I mean dishes bathing kids etc...NOT NORMAL I am exhausted by the end of the day. I have had my heart cleared at clevland heart clinic I had mild regurgitation in my tricuspid and pulmonary valves which they said was not causing the high heart rate needed to look into thryroid and IST and POTS for a diagnosis. And now I am having trouble swallowing and some pain in the right side of my neck....anyway the heart rate is effecting my quality of life and I have a docs apt but they would not get me in until middle of september so I must wait. My question is can hosimotos cause high heart rate I was told yes and then I was told NO.....or sometimes you can have hosimotoxocious I probably spelled that wrong....where you can have symptoms of HYPER but have hosimotos which causes HYPO.....any help would be greatly appreciated!!!!!

My official diagnosis a year ago was Hashimoto's Toxicosis. Which is what they call it when you have Hashi's, but are in an extreme hyper phase.

It happens when you plug along taking your Synthroid and your thyroid starts dumping hormones you didn't know you had into your body. Suddenly your Synthroid is like poison and you find out a couple weeks later.

"UH, your TSH is REALLY low. You better stop taking your Synthroid."

When I was so hyper I couldn't get out of bed the worst part of it was how my heart felt. Just lying down would make it beat faster, and it felt like it weighed ten pounds. When I was hyper but functional, several months, I still had the same heart symptoms.

Now I am extremely hypo. two weeks ago my TSH was 120. I hope it's falling, but it's probably somewhere between 50 and 80. I am tired constantly and all my muscles ache, including my heart. When I lay down, my heart rate goes up about ten beats per minute. It's irritating, but bearable.  

Nice to know it's not just me.

Thanks for posting that, AR-10!  It is helpful to know that others suffer the same strange symptoms. -- MDs haven't explained to me WHY the palps happen when I'm laying down.  As far, as I know I haven't crossed over to hyper (yet).   Both endocrinologist and primary care MD told being me hypo can cause palps and rapid pulse.  -- Hope you're feeling better soon!! Tsh of 120 has to tough. Good luck!

Thanks for your post ...I can't imagine 120, I feel like crapola at 25...your story is the same  as mine, but I had RAI to stop the thyroid from dumping, so far it's been ok   haven't had any major  hyper issues in 3 months, my blood sugar has returned to normal too. And my heart rate hasn' went over 80....almost feel normal...almost ...still alot of pain, and some brain fogs.

I do NOT have Hashimoto's (meaning that I do not have thyroidperoxidase antibodies), but I definitely have hypothyroidism. A rapid heart rate is not on the standard list of symptoms, but it has been one of my body's favorite ways to tell me that my thyroid gland was not doing a fully competent job. You mentioned having a doctor's appointment in mid-September. I hope it is with an endocrinologist. I think there is far too much to know about the endocrine system, and problems with it are far too complex, for a general practice doctor to be messing around with hypothyroidism. My GP agrees!

Frankly, likely having both, I'd much rathe have IST than thyroid disese.

If the Good Lord told me I could have a resting heart rate of 60 (instead of often 100+) or be free of Hashis, I'd easily choose to be free of Hashis, hands down. Heart rates wax and wane and the rhythm itself isn't dangerous if it's sinus rhythm.
If you had the sympyoms of  true hypothyroidism you'd understand...

Good luck with your appointments
