I am going to be having RAI next Thurs. and am off all meds in preparation for this. So, I am completly hypo.
I have been having most of the typical hypo symptoms (fatigued, achy, swollen eyes, etc.), but my heart rate is really fast. I also have a lot of anxiety, but figured being hypo should slow my heart rate down. It's done just the opposite. It is now faster than ever and this causes me to feel very short of breath.
I was just wondering if anyone else has experienced this with hypothyroidism.
Hi. I have not experienced constant rapid heartbeat. However, I have experienced short periods of rapid heartbeat as well as skipped beats. I have noticed that in times of anxiety (and I've had plenty of that this year!), my symptoms seem to be present more often. I am new to this message board and also newly diagnosed as hypo-T. So I am learning a lot from the people here-more than my doctor has told me, that's for sure! Good luck with your tests and let us know how they turn out.

Hilery, My constant rapid pulse(100+) was part of the reason they kept trying to say I wasn't hypo. It's a viscious circle too. When your heart is racing, it creates more anxiety and makes your heart race. Be sure you're taking magnesium if you can. And remember the fast pulse won't hurt you on a short term basis, it just feels awful. You'll be fine. Make sure they put you on a T3/T4 drug when this is over so you won't have to wait so long for your symptoms to go away. Hugs, IWL
Thanks for your replys!
Yes, I started taking magnesium a few days ago. So, hopefully it will help some.
I know my dr. is planning on putting me on synthroid once my treatment is done. I'm wondering if that will just make my heartrate even higher.
Yes I experience this, sometimes with a vibration type feeling in my chest. Im not sure what this is but seems may be a hyper symptom even though I am hypo.
Hilery, The only reason I brought up them putting you on the T3 is that it works so much faster than T4 alone, so you wouldn't have symptoms as long. Hugs & Prayers, IWL
hypo-fast heart rate?
