What is AFib?
Charge 5 on wrist Charge 5 on wrist

Atrial fibrillation is an irregular heart rhythm and occurs when the upper chambers beat out of sync with the lower chambers. This can increase risk of blood clots, stroke and heart attack. Adults over 40 have a 1 in 4 risk of developing AFib in their lifetime.2

AFib is treatable, so the earlier you identify it, the sooner you can do something about it.

Why it's hard to diagnose
Phone in hand Phone in hand With AFib, the heart may not always beat irregularly, making it hard to detect, even in a doctor’s office. Palpitations and shortness of breath can be symptoms of AFib, but some people don’t have any symptoms.

To check for signs of AFib, use the Fitbit ECG app to assess your heart rhythm on demand or have Fitbit analyze it while you’re still or sleeping.

Armed with this information, you can connect with your healthcare provider and have a more informed discussion.

Check on demand with the ECG app

An electrocardiogram (ECG or EKG) is a test that measures your heart’s electrical activity. Fitbit’s ECG app records those electrical signals and looks for signs of AFib. To take a heart rhythm assessment, set up the ECG feature in the Fitbit app.3
