Buying a cuff is easy. Buying a cuff that matches evidence is a slightly slower search.
Why the upper arm wins for most people
Guidelines generally prefer automated upper-arm devices listed on validation sites. Wrist cuffs sit farther from the heart and wander if you talk or hold the arm wrong.
- Look for a validated model
- Match cuff size to your arm
- Practice the five-minute sit
Smart features are extra
Measure your arm. A cuff that is too small reads high. Fashion colours do not fix physics.
An app log is convenient. A notebook works. Irregular heartbeat flags are prompts to talk to a clinician, not a diagnosis of AFib. Follow up in person.
