Overview
Released––
Measuring
TypeUpper armUpper arm
Clinically validated–Yes
Irregular heartbeat detectionYesYes
AFib detection or ECG–No
MethodAutomatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use; first on-sale date not establishedAutomatic oscillometric upper-arm measurement; exact HEM-7121J-E. First retail sale period unresolved; manual publication and warranty dates are not substituted
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 pressure accuracy ±3 mmHg and pulse accuracy ±5% of displayed reading; blood-pressure range 20–280 mmHg, pulse 40–180 beats/minute and cuff pressure 0–299 mmHg
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the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished.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 approves the exact model for adult home use by equivalence to HEM-7130, whose referenced study used ESH-IP 2010 and was published in 2015; this is not a separately published exact-model trial. Medaval separately says the equivalence results are unpublished and cannot be verified for its MDR assessment. Maker manual cites an 85-subject EN ISO 81060-2:2014 investigation and compliance with 2019+A1:2020, excluding pregnant and pre-eclamptic patients
FeaturesIrregular heartbeat indicator, pressure progress bar, WHO classification indicator, stored-reading average and automatic power-off; irregular heartbeat indication is not a specific AFib diagnosisIrregular-heartbeat and cuff-wrap indicators; no body-movement, high-blood-pressure or averaging feature in the exact maker table. No AFib screening or ECG recording; generic BPM & ECG category wording does not establish an ECG feature
