You have been asked to use the CardioSignal app to check for atrial fibrillation (AF) which is a type of irregular heartbeat. People with AF are more likely to have a stroke than people without AF and so it is important to check whether your heart rhythm is normal.
AF becomes more common as we get older. People who have conditions such as diabetes or heart failure are also more likely to have AF. AF is usually detected by a simple pulse rhythm check. Follow this link for more information on AF.
CardioSignal is an app which can detect AF using technology within your mobile phone. The app is widely used across Europe but is new to the UK. Your GP surgery is taking part in a new project to see whether using CardioSignal will improve the diagnosis of AF in the UK health system.
