Frequently Asked

How does a wrist heart sensor work?

It shines light into your skin and measures how blood flow changes the reflection — a technique called photoplethysmography. Motion and fit affect its accuracy.

Is a watch ECG the same as one at the doctor's?

No. A watch records a single lead; a clinical ECG records twelve. The watch can flag irregularities worth checking, but it cannot diagnose.

Is this medical advice?

No — it's education about how devices work. If a sensor shows readings that worry you, or you have symptoms, see a doctor rather than a spec sheet.
