With a compatible ECG app right on your wrist, screen your heart anytime for atrial fibrillation (a heart rhythm irregularity), and share the results with your doctor.

Once you download the ECG app for your Fitbit device, open the heart rhythm assessment in the Fitbit mobile app to begin.

The Fitbit ECG app is only available in select countries; not intended for use by people under 22 years old.
