Measuring
TypeUpper armUpper arm
Clinically validated–Yes
Irregular heartbeat detectionYesYes
AFib detection or ECG–Yes
MethodAutomatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use; first on-sale date not establishedAutomatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use
AccuracyMaker specification ±3 mmHg pressure and ±5% pulse; pressure range 0–299 mmHg, systolic 60–279 mmHg, diastolic 40–200 mmHg and pulse 40–180 beats/minMaker specification ±3 mmHg pressure and ±5% pulse; pressure range 0–299 mmHg, systolic 60–279 mmHg, diastolic 40–200 mmHg and pulse 40–180 beats/min
Clinical validationA&D UK claims ESH 2010 validation; Medaval identifies the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished. The US Validate BP listing covers UA-611 under ANSI/AAMI/ISO 81060-2:2018 with different cuff options; this does not establish direct validation of the supplied UK cuff configurationSTRIDE BP lists UA-611Plus as equivalent to the validated UA-1020, citing 2013 BHS 1993 studies; this is approved device equivalence, not a direct UA-611Plus validation study. A&D's shared manual separately states ISO 81060-2:2013 clinical testing
FeaturesIrregular heartbeat indicator, pressure progress bar, WHO classification indicator, stored-reading average and automatic power-off; irregular heartbeat indication is not a specific AFib diagnosisIHB/AFib screening indicator, pressure progress bar, WHO classification indicator, stored-reading average and automatic power-off; maker says AFib screening is for monitoring and not diagnosis
