ScanWatch can detect atrial fibrillation (AFib) when recording an ECG. But it can also check for signs of AFib throughout the day and night, using a PPG (photoplethysmography) sensor that emits green light and measures its reflections on the blood vessels in the wrist. When the blood flows, the reflection of light changes. Learn more.
An exclusive algorithm analyzes the signal. If your heart rate is atypical (low or high), or if an irregular rhythm is detected, you will receive a notification.
You can see your signs of AFib data on your Health Mate app.
Your latest signs of AFib will be available on both your Home screen and Dashboard.
Note: You cannot receive signs of AFib notifications if you haven’t enabled them beforehand. To activate them, please go to the Devices tab of your Health Mate app then go to All Settings > Health Features > Signs of AFib and follow the on-screen steps.
