HR won't rev up.
I went from a maximum sustainable HR of 160+, down to 123. I had some thyroid issues and now the doc says my thyroid level is ok. HR has come back up to 130 or so, but of course thats not good enough to RIDE. I have the Tour de Phoenix coming up and I'm getting desperate for an answer. The tour is gonna be tough with a max HR in the 130s. Here is a link to my last hill climb. https://connect.garmin.com/activity/70050097
I had the heart checked out and did the stress test and everything was great, except for the HR. I went anaerobic at 123 that day. The heart doc. said when I get the thyroid levels correct the HR will come back. So much for his idea. Help.

A couple of questions:
1. How do you know you went anaerobic at 123?
2. Have you considered a metabolic test?
Endurance Rehab is the recommended place near you for metabolic testing. It isn't cheap, but it provides solid data on your lactate threshhold, VO2Max, etc. You'll know for sure where your HR zones should be, and get an idea of how much O2 you can get to your muscles at your reduced heart rate.
Your monitor is providing the same range of numbers as your doctors?

1) I know when I go anaerobic.
2) No I haven't. How would that be helpful?
3) I doubt my medicare would cover it.
4) I had my garmin HR monitor on while I took the stress test and they were exactly the same.
I can't believe the problem is not related to my thyroid, but now that my thyroid level is OK, that seems to rule that out. There must be something else the jump starts the heart beat with a increase in activity.

Yes, you have a problem. I'd try an internist for sure. The thyroid does regulate HR, but the mechanisms are very complicated. I don't think it's as simple as having an OK "thyroid level."

Because internists deal with subtle issues of internal chemistry. Maybe an endocrinologist would be even better. Talk to your doc about a referral. The medical fields are so involved now that a GP mostly knows who to refer you to.
