About AFib and AFib History
Atrial fibrillation (AFib) is a type of irregular heart rhythm where the upper chambers of the heart beat out of sync with the lower chambers.
According to the CDC, approximately 2% of people younger than 65 years old and 9% of people 65 and older have AFib. Irregularities in heart rhythm become more common as people get older. Some individuals with AFib don’t experience any symptoms. Others experience symptoms that could include rapid heartbeat, palpitations, fatigue, or shortness of breath.
AFib is a chronic condition, but the amount of time people spend in AFib can change. People with AFib often live healthy, active lives. The amount of time your heart is in AFib can potentially be reduced with regular exercise, a heart-healthy diet, a healthy weight, and treatment of other medical conditions that could worsen AFib. If left untreated, AFib can lead to heart failure or blood clots that may lead to stroke.
AFib History gives long-term visibility into the amount of time your heart shows signs of AFib, also known as AFib burden, so you can share this information with your physician for richer conversations.
Apple says the feature is intended for use by individuals aged 22 years or older who have been diagnosed with atrial fibrillation.
ECG, Irregular Heart Rhythm Notifications, and AFib History are features that can be used by Apple Watch owners in over 150 countries worldwide. Apple maintains a dedicated list of Apple Watch feature availability on its website.
