Heart rate 48 bpm!

[fortunata]

I’m currently on holiday (from England) in Montana. I’ve been living at between 5,000 and 6,000 feet above sea level for a week and a half now.

I’ve been taking my usual dose of 60mcgs a day of Liothyronine and I’m a bit worried that my pulse rate has gone down to 48bpm. It’s usually around 54. Do I need to worry? Does anyone have any idea why it may have dropped so low?

If I was in the same situation as you I'd add a little more T3 to see if it is helpful. After all it is the 'energy' in our body.

You can always reduce dose back down without too much bother.
