Checking your heart rate can help identify early signs of atrial fibrillation (AF). Learn how to perform a manual pulse check or use a mobile device to monitor your heart rate and understand what an abnormal heart rate might indicate. Medical checks are needed to confirm if you have atrial fibrillation.

We are continuing our long-running partnership with British Heart Foundation, with our joint funding now being administered by the BHF Clinical Study Grants scheme.
