What’s an ECG?
An electrocardiogram (ECG or EKG) is a test that measures the electrical activity of your heart.
What does the Fitbit ECG app do?
The app brings ECG technology to your wrist so you can record your heart’s rhythm when it’s convenient for you.
How does it work?
There are sensors in the frame and biosensor core of Sense and Charge 5—open the Fitbit ECG app and place your fingers on the corners (Sense) or on the sides (Charge 5) for it to record the signals from your heart.
Why is assessing for AFib important?
During AFib, the upper chambers of the heart contract irregularly, increasing the risk of heart attack, blood clots, stroke and other heart conditions.
AFib can be difficult to detect, but the Fitbit ECG app lets you check in on your heart rhythm right from your wrist—so you have a better chance of spotting and treating it. This assessment can’t diagnose AFib on its own, but your results can help you have a better conversation with your doctor.
Possible results
Normal Sinus Rhythm
Your heart rhythm appears normal. It doesn’t show signs of atrial fibrillation (AFib), an irregular heart rhythm.
Atrial Fibrillation
Your heart rhythm shows signs of atrial fibrillation (AFib), an irregular heart rhythm.
Inconclusive
If your heart rate is over 120 bpm or under 50 bpm, the Fitbit ECG app can’t assess your heart rhythm. You might also get an inconclusive result for other reasons, like moving too much while taking the assessment or incorrect finger placement.
More to know before you start a heart rhythm assessment:
The Fitbit ECG app can’t detect heart attack, blood clots, stroke or other heart conditions. If you think you’re having a medical emergency, call emergency services.
The Fitbit ECG app is not intended for use by people under 22 years old.
You should never change your medication based on any result of the Fitbit ECG app without first speaking to your doctor. The results of the Fitbit ECG app may not be accurate in people who take medication or substances that affect heart rate or blood flow.
