[hcurrie]

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 ...

How are you sleeping ??  

I am hyperthyroid, but I have all the symptoms of hypo.  My heart rate is super slow, between 58-62 bpm.    

In the past, when I had bad heart palps, if it wasn't anxiety, then sleep deprivation was the cause.  The more tired, I felt the more my heart would pound  I was mentally awake & alert, but my body was telling me, I needed to rest.  

Poor sleep, can cause alot of health symptoms for people.  Or just not resting enough, when our bodies are not feeling well.

I am having a recurrence of heart palpitations, especially at night when I roll over. Two years ago, the same thing happened and the doc checked out my heart and decided it was anxiety even though I kept telling him it was my thyroid because of all my other symptoms (thyroid checked out normal at that time). He put me on antidepressants which did nothing. Finally, after another 6 months, he ran another thyroid test (at my insistence) and found out I was hypo. After, being on thyroid medication for 2 weeks, the heart palpitations went away and have been gone until now. My doctor never ran any other tests on my thyroid to know what was causing the problem so I am assuming that my thyroid is now getting worse. As far as the palpitations being related to lack of sleep, how can that be when I sleep very deep and every chance I get?

Hi,
My cardiologist told me, that many thyroid patients have sleep apnea, especially those with enlarged thyroids.  Such as in my case.  The thyroid can surpress the airway, while I sleep, restricting oxygen, regardless of how many hours I sleep.

I wake up feeling tired, my heart overworks, to keep energy levels balanced.  My heart used to pound bad, just walking around my house.  And sometimes when I didn't feel tired, my heart would still pound, just walking, and pound at night, when I tried to sleep.  

But sleep apnea, is one contributing factor to heart palps according to my cardiologist.  

I was making frequent visits to my cardiologist for bad heart palps, had every heart test done in the medical field, all return normal.  Stress test, ultrasound, echo, 24 hour monitor, etc...  

But he said, many thyroid patients visit him, with heart palps, and he diagnosed sleep apnea, with most of them, after reviewing thier medical history and lab results.    

I'm not a doctor, just sharing what my cardiologist shared with me.  Please consult your doctor for proper care & treatment.  

Hope you feel better soon.  Good luck to you !!

Heart palps are NO fun. Neither are runs of tachycardia., chest pain,ect

You should see a cardiologist, better yet a electrophysicist cardiologist ( they specialize in electrical activity of heart). Get a complete cardiac workup.... just to get a clean bill of health. They ( drs) can also prescribe something to help the palps, make you feel betterI

. Being told you are crazy without getting a complete cardio workup... well thats nuts!!!

And someday we will prove the cardio/heart connection to all those "slow thinking" drs.

Hi, I just wanted to say that I get awful palpitations and have done for a year whilst swinging between normal and hypo. But I am also undergoing a premature menopause too which can cause palpls, so I'm not sure how old you are, but you might want to look into that side too. But in any case, I was told by the experienced people here when I first joined that a lot of the symptoms of hyper and hypo overlap, and they don't always fit in with the traditional picture, ie. palps commonly associated with being hyper. And also, whenever I get them, it has been when I'm hypo!

Several years ago I started experiencing palpitations. Went to a cardiologist and he put me on Atenolol to regulate the beat. Now 4 years later and after many complaints about  my neck, I've been diagnosted with hoshimotos hypothyroidism. Started getting the other symptoms before the actual diagnosis.
