Apple Watch has 97-percent accuracy in detecting abnormal heart rates

According to a recent study, it was found that the Apple Watch was able to detect abnormal heart rate or atrial fibrillation with an accuracy of up to 97 percent.

Atrial fibrillation is characterized by irregular or rapid heart beating. Most episodes may have no symptoms, but it is associated with higher risks of heart disease, heart failure, and dementia.

They found that when paired with an algorithm to sort through the collected heart rate data,  they were able to detect atrial fibrillation with 98.04-percent sensitivity and 90.2 percent specificity.

The study was conducted by the University of California and the team behind the Cardiogram app. There were 6,158 participants in total and all had normal EKG readings. However, the tests found that 200 of them suffered from paroxysmal atrial fibrillation.

Cardiogram is available for download from the App Store for free.
