But Fitbit is not wasting any time and has already released the functionality into the wild. Reddit users in Europe and the US have started reporting they are now able to install the ECG app.

How to take an ECG reading
The app brings ECG technology to your wrist allowing you to take readings on demand. This is the first Fitbit with the functionality. We’ve seen it on other watches before, including those made by Apple and Withings.
To take a reading open the ECG app and place your fingers on the corners of the stainless steel ring of the watch. The sensors are located in the frame and biosensor core of the device. After 30 seconds Sense and the smartphone app will show results which can be shared with a doctor at the press of a button.
The possible results are: Normal Sinus Rhythm, Atrial Fibrillation and Inconclusive. This last one appears if your heart rate is above 120 or under 50 beats per minute. It might also appear if you’ve moved too much while recording or placed your fingers incorrectly.
