Fitbit’s ECG app, which works with Fitbit Sense, has passed local regulatory clearance in Singapore, meaning it is an accurate tool for monitoring the electrical activity of your heart.
Apart from being able to assess heart rhythm and monitor heart health, the Fitbit Sense is now able to help doctors assess if you have heart issues such as atrial fibrillation (AFib). The app doesn’t diagnose AFib, but the readings it provides help doctors in their assessment.
AFib is an electrical problem that causes the atria to beat erratically, which increases the risk of serious heart conditions like stroke. AFib is not easy to detect and currently affects more than 33.5 million people globally. Some studies suggest that as many as 25 per cent of AFib-related stroke victims only found out about AFib after their stroke.³
How it works: the two electrical sensors on the Fitbit Sense that are in contact with both sides of your wrist and the closed electrical circuit lets the ECG app record the electrical signals from your heart and analyse them for AFib. The app will then tell you if your heart rhythm appears normal, shows signs of AFib, or if the assessment was inconclusive. The results can be exported into a PDF so you can share them with your doctor.
