- Role
-
The watch analyzed ECG recordings and displayed QT and QTc values.
- Configuration
-
The participant used a Withings ScanWatch.
- Inputs and outputs
-
Not assessed
- Autonomy
-
Not assessed
- Workflow
-
The wearer records ScanWatch ECGs and the QT function reports a prolonged interval. The wearer or a clinician takes the displayed values to a cardiology service. Clinical ECG and genetic testing confirm an inherited channelopathy.
- Human oversight
-
Not assessed
- Relation to AI
-
The watch's automated ECG analysis displayed the QT and QTc values that prompted the clinic visit. No automatic alert is described. The report does not say who first noticed the values. Diagnosis rested on clinical ECGs and genetic testing.

Follow-up
- Conditions for replication
-
The QT function is available in the wearer's region and firmware. Recordings are of adequate quality. Cardiogenetic evaluation and family screening are accessible.

Consumer wearable inferring a health measure from sensor signals: ScanWatch's QT values proved true, while Oura's sleep-staging algorithm was allegedly less accurate than claimed, harming ring purchasers who relied on it.
- Field
-
Healthcare (cardiology; clinical genetics). Consumer wearables.
- Purpose
-
The ScanWatch records a single-lead ECG and, in the version described, includes a QT monitoring function. Flagging a prolonged QT interval was within what it was built to do.
