Increased Heart Rate During Running Sessions. Have Under Active Thyroid, Migraines. Suggestions?
my normal heart rate is about 45 beats per second - when I train/run my watch beeps saying heart rate 175 sometimes 180 - is this ok - I'm training for a half marathon and this happens when I'm running up hills....I was out training tonight and haven't worn the watch in a while but it kept beeping....thanks.
I have an underactive thyroid and am on 25mg beta blocker for long term migraines - hence slow heart rate? I'm female and 49 years of age ...many thanks

Dear patient,
The predicted target heart rate during peak exercise is predicted with the formula 220 minus age; in your case, it gives us 171, which is precisely the ball park that your pulse sits according to your watch, therefore, a normal, actually good response, since you are able to achieve that number.
Yours truly,
