I looked all over and searched for the information and just can't seem to find much. I was wondering if a symptom of hypothyroid is that when you exercise your heart rate goes very high, even at moderate intensity.

Any info would be great,
Thanks

Not that I've heard. Hyperthyroid, the opposite condition, is usually associated with rapid heart rate, generally hypothyroid is the opposite. You might want to use google though, I don't claim to know everything about it.

That happened to me in the very beginning of hypothyroid when my thyroid began to slow down. It took years to recover to where my exercise heart rate returned to a normal range. I have not read anything to confirm the connection to low thyroid, but I suspect it is connected somehow, even if only from over training and stressing the thyroid beyond it's healthy output.

Yes that can occur when your adrenals are not addressed if you are hypothyroid. I have poorly functioning adrenals and when I first went on my thyroid meds my heart almost jumped out of my chest during exercise. My doctor and I then realised that I needed to sort out my adrenals.
