I can't figure out why my heart rate is still high

[Guest guest]

I am now on 85 mcg of cytomel, and am tapering down a little from 55 mg of HC to

52.5 mg. My temps are stable, still, and I don't really have low cortisol

symptoms, whereas I used to have low cort symptoms with high heart rate, and

when I increased the HC, my heart rate would decrease.

I am supplementing iron now, and I do have low ferritin, but highish serum iron,

so I am not sure if this is the cause of the high heart rate. I have to watch

how much iron I take because last time I supplemented, my iron came out really

high on a test.

I finally feel like I am not hypo, and my temps are around 98.0, which is fine

with me, but I am worried I can't tolerate the T3 at a high enough level for me

for some reason.

I am supplementing sea salt a lot and it is not helping, either.

Are there any other reasons why my heart rate could be high?

The only other thing I can think of is that my free estradiol levels could be

low due to high shbg.

I have read that low magnesium can increase heart rate, too. Is this true?

If anyone can think of other reasons why heart rates can go high, please let me

know.

Also, for what its worth, my heart is pounding very hard. It moves my whole body

when it beats.

Thanks
