I’ve noticed that my blood pressure readings can be different depending on which arm I use. The gap isn’t always the same, and I’m not sure whether I should compare a single pair of readings or look for a consistent difference over several days.
For people who have tracked blood pressure readings between arms, what’s a sensible way to measure them at home? At what point is a repeated difference worth raising with a clinician rather than assuming it came from cuff position, timing, or measurement technique?
