AFib detection or ECG: Yes
Method: Automatic oscillometric upper-arm measurement during deflation with semiconductor pressure sensor. First-sale date unresolved
Accuracy: Pressure 30–260 mmHg; pulse 40–199 bpm. Maker accuracy ±3 mmHg pressure and ±5% pulse
Clinical validation: STRIDE BP lists Z5 as equivalent to the validated Rossmax CF175, rather than directly studied. Medaval says the equivalence evidence is unpublished and cannot be checked against MDR requirements; headline validation omitted
