High Resting Heart rate

[Lilacsocks]

I was wondering if anyone else experiences a high Resting heart rate when under treated? I shared my last blood results in a previous post but T4 was only 30% through the range and I have been feeling exhausted, cold and shivery so I'm pretty sure I am under treated.

Its makes me feel uncomfortable and really unfit my resting heart rate is high, in the 90s (it's a bit higher since I've been pregnant) when I've been feeling fit and well it's more like 70. It also makes me worry about upping my dose. Does anyone else have experience with this?

I have read under treatment can cause palpitations but this is more like all the time.

Yes my resting heart rate undermedicated is around 90.

Yes, my resting heart rate has always been 110-120 even when medicated.

Yes, me. My resting heart rate is all over the place - it can be anywhere from the 70s up to 130, and usually averages around 90 - 110.

I know that low iron and/or low ferritin (iron stores) raise my heart rate so I do my best to keep iron and related measures as close to optimal as I can. As a result I have to take a maintenance dose to stop it dropping.
