How to record an ECG ?

Simply press the side button once and gently place your fingers on the bezel (top ring) for 30 seconds. Stay still, don’t move or talk, and relax—it’s best to be seated or to place your arm on your leg, and try not to contract your arm and hand muscles. The watch will vibrate to notify the user that reading is complete.

What actually happens

By placing his opposite hand on the watch, the user creates a closed electrical circuit with his arms and chest, allowing the measurement of a one lead ECG.

 

After each measurement, Withings ECG devices give you the following metrics :

- a heart rate
- a lead D1 ECG tracing
- a rhythm prediction between 3 classes (normal sinus rhythm, atrial fibrillation, inconclusive).
