Heart rate?

My sitting resting heart rate is usually high 50’s or low 60’s
But when I stand it increases to 80
Not sure if any of you are familiar with Pots Syndrome but does that sound like something that I should be concerned about ?

My resting is anywhere from upper 50s to low 80s and when I walk runs between 90 and 110. While doing cardio or a nice vigorous bike ride it runs around 150 to 160.

When you say yours goes up to 80 when you stand to me that's still a low reading. I think everyone's goes up a bit when they stand and start moving around a little (so we don't pass out).

Didn't look into Pots, but even so, sounds normal to me.
