New AFib History Feature
Thanks to the ECG app, your Apple Watch can help you detect possible atrial fibrillation (AFib), which can cause many health problems for you and even produce a stroke.
Not only that but the more time you spend in atrial fibrillation, the more problems you can have. Now, with watchOS 9, people diagnosed with AFib can track how often their heart rhythm shows signs of AFIB with the help of AFib History.
You’ll get weekly and monthly insights into what your heart rhythm was like, and you can even download that information as a PDF file and share it with your health provider.
