Apple just unveiled its latest smartwatch, the Apple Watch Series 4, and it has one impressive new medical feature: a built-in single-lead ECG (electrocardiograph).
The FDA has cleared it as a medical device, according to Apple, and we assume the clearance is for detecting certain cardiac arrhythmias, particularly atrial fibrillation.
Previously, the KardiaBand from AliveCor offered the same feature via a small attachment to the Apple Watch. We reviewed that product and were very much impressed by its performance. In principle, a great deal of people that have cardiac arrhythmias may be helped with such technology if only the random, infrequent, and erratic events can be spotted, recorded, and analyzed.
Here’s an Apple promo video for the Series 4 Apple Watch:
