Method
Method	Automatic oscillometric upper-arm measurement during inflation. UK item 65400, EAN 4211125654009; manual type BM 64. Announced on 12 November 2023 with planned German availability from March 2024; actual first-sale date unresolved	Automatic oscillometric upper-arm measurement during deflation; first on-sale date not established
Accuracy
Accuracy	Manual display accuracy ±3 mmHg for systolic and diastolic pressure and ±5% for pulse. Systolic range 50–280 mmHg, diastolic 30–200 mmHg and pulse 40–199 beats/minute; maximum cuff pressure 300 mmHg is separate	Maker manual specifies static pressure accuracy of ±3 mmHg and pulse accuracy of ±5% of the readout value; this specification is distinct from clinical validation
Clinical validation
Clinical validation	Current manual claims clinical testing to ISO 81060-2; independent validation for this exact model not established. The shared launch release's pregnancy-validation claim belongs to BM 53, not BM 64	Microlife states clinical testing for several populations; exact independent registry confirmation for BP B4 AFIB BT was not established
Features
Features	Advanced arrhythmia detection flags possible atrial fibrillation, without recording an ECG. Coloured classification scale, cuff-position check, HSD resting indicator and low-battery indication. Maker retains triple-measurement mode; May 2024 instructions describe three measurements with 30-second waits and a final average, while September 2026 instructions omit that operation section	AFIBsens indication operates only in MAM mode and can be switched off separately for each user; separate irregular heartbeat warning, cuff fit and movement checks, classification scale and adjustable date/time
