Recording an ECG

To record your ECG, perform the following steps:

1. Make sure ScanWatch 2 is snug on the wrist you selected in the Withings App. 
2. Press the side button of the watch and scroll to the ECG mode. Press the button to select the ECG mode.
   
   
3. Place your fingers on the bezel (top ring) for 30 seconds. Stay still, don’t move or talk, and relax.
   Important: Try not to pinch or grip the watch too hard.
    
   
   The ECG recording starts after a first vibration. Please remain still during the measurement process. It is better to be seated or to place your arm on your leg, and try not to contract your arm and hand muscles. ScanWatch 2 vibrates twice when the ECG recording is completed.
   
   Important: When recording your ECG, the watch will give you 3 attempts to take a measurement. If the ECG recording fails on the third attempt, the watch will vibrate twice. If you wish to attempt a new ECG recording, you will have to short press the side button on the watch to start again.
    
4. Tap Done.
