Heart Rate Limitations Show Why You Shouldn't Get Your Medical Advice From the Apple Watch:
The Apple Watch is the smartwatch to beat. It's massively popular, has a full range of features, and compared to some of its competitors, leads the way in rethinking how wearables can function within the health sector. During the Apple Watch portion of Apple events, you can generally expect a feel-good reel of real-life users sharing stories of how the watch saved their lives by notifying them of their irregular heartbeat. That said, Apple's own FDA application for its ECG app admits the watch does not detect atrial fibrillation (AFib) for heart rates exceeding 120 beats per minute—a limitation that a Forbes report suggests could leave a large number of Apple Watch users with a false sense of security.
That 120bpm limitation is, as it turns out, significant, according to Forbes. Mayo Clinic says that the heart rate of AFib patients can range anywhere from 100 to 175bpm—meaning the Apple Watch isn't looking at a decent chunk of folks who may be affected.

How is a smartwatch supposed to detect AFIB? Irregularity in the (nominally regular) timing between beats? How would that distinguish AFIB from VFIB? It's not like there's a dongle attachment for chest electrodes. That's my fucking idea, don't you steal it. $2000 bucks thank you come again.
But seriously, how does fib detection work on a smartwatch or even a smartphone?
