Atrial fibrillation: Apple Watch wrong in 59% of cases?

Apple Watch is equipped with several sensors that allow it to monitor our health and in the latest models it is able to detect atrial fibrillation (AFib). In this way, in recent times it has “saved” lives, but apparently this detection it is not foolproof.

The reason for these limitations is related to Apple Watch’s inability to detect atrial fibrillation when the wearer’s heart rate is above 120 beats per minute. According to the case studies of the study in question it is 59% of cases.

In another recent clinical study published in Circulation, researchers examined the Apple Watch’s ability to detect it in a group of patients in post-cardiac surgery. The study found that the Apple Watch detected the anomaly alone 34 cases out of 90, with an accuracy of only 41%.

Before shouting to the scandal it is good to remember that Apple has never claimed that its smartwatch has a 100% success rate, much less in the case of atrial fibrillation. A 41% success rate is still better than the 0% you would have if you didn’t wear an Apple Watch at all.

However, if you are worried about your health, do not rely on a smartwatch but consult your doctor who will surely know how to help you.
