The Apple Watch has an ECG whose sole purpose is to detect signs of AFib. I'm guessing since they made the scope so narrow that they don't get a lot of false positives.

Yes, to my knowledge, determining "afib" is "not afib" is the only validated use of watch-based ekgs.

It’s about the only thing you could use it for as it only gets the arm leads it can’t even determine axis which it would need to diagnose things

Aren't these totally different technologies? I thought ECG was for detecting arrythmia and is very very clear that it can't detect a heart attack. EKG is what they use to detect heart attacks. Lots of watches and devices have ECG functionality at this point, very few have EKG let alone approval as functioning well enough to be advertised.

At least that's my understanding from a very quick look around at watch health features come in smart watches these days.

EKG and ecg are synonymous. One is electrocardiogram, one is electrokardiogram. Depends on how Germanic you're feeling.
