Health Canada has approved the AFib history feature for the Apple Watch and iPhone, which is part of the upcoming Wear OS 9.0 software update. The U.S. Food and Drug Administration (FDA) has approved the Apple Watch ECG and Atrial Fibrillation History features.
What is Atrial Fibrillation (AFib)?
Atrial fibrillation (AFib) is a type of irregular heartbeat (also called arrhythmia). In AFib, the heart’s two upper chambers (the atria) beat too fast and out of sync with the two lower chambers (the ventricles). If not treated, AFib can lead to a stroke or heart attack. So, getting diagnosed and treated as soon as possible is important.
Even though it is not a medical-grade device, the Apple Watch can still be used to detect signs of AFib and now the AFit history. This gives you an idea about how often a user has had an AFib, making it easier for the doctors to understand the severity of the condition.
Apple Watch Models with ECG
The Apple Watch AFib history feature will be available on the following models running on Wear OS 9.0:
- Apple Watch Series 7
- Apple Watch Series 6
- Apple Watch Series 5
- Apple Watch Series 4
Plus, the upcoming Apple Watch Series 8 will also have this feature along with other health tracking features such as temperature monitoring, blood oxygen level monitoring, etc.
The Apple Watch ECG and AFib detection features are unavailable in every country. As the health authorities evaluate and approve these features, they will be made available in more countries.
