Upper Arm Blood Pressure Monitor

An upper-arm cuff is the type most clinical guidelines point to, because the artery it reads sits at roughly heart height and moves less than the wrist. This one inflates gently, holds two users of sixty readings each, and flags an irregular heartbeat while it measures.

Take readings seated, feet flat, after five minutes of sitting still — and take two, a minute apart. A single number in isolation says very little; the same reading at the same time each day is what tells a story.
