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?
