I don’t measure my blood pressure out of the doctor’s office, so I don’t have a good sense of how elevated above base level it is at doctor’s office. I measured 95/62 at my last doctor’s visit, so the potential concern would be too low rather than too high.
However, I do measure my resting heart rate at home – both manually and via my Fitbit. Both show a RHR near ~40 under true rest conditions at home, while I’m closer to 50 in a typical doctor’s visit. If I measured 40 in doctor’s office, I suspect I’d be flagged as too low (before I mentioned my athletic training/history), but 50 does not get flagged.
