HR Tips

I have an Apple Watch that monitors my heart rate, mom (a nurse) suspects that I could possibly have POTS. We want to try and get an alert that specifically alerts me when my heart rate spikes just when I’m standing. I currently have my watch doing the resting hr alert but that’s not very helpful for this situation. I was just wondering if anyone had any tips for what to do. I know the doctor is the easiest option but we were just trying to see if this is a one time thing or if it’s been going on longer than either of us realize. For background I was complaining of low bp and she did the laying/sitting/standing bp and hr. My bp is fine, turns out what I’m feeling is tachycardia yay Usually she’d just retake my hr again periodically but I’m going back to college. I appreciate all the help y’all!
