No, no, no, no, no. This is so fantastically wrong. I can't believe this got approval.
You cannot do an EKG/ECG from one lead. It's not an EKG.
Second, I can't think of a way you would be able to determine rhythm from one lead. The physics aren't there. You need at least 3 leads just to do telemetry, which is what you see when someone is on a heart monitor at the hospital. It might be able to determine whether a rate is irregular, but that's about it.
This has fraud written all over it. I wouldn't rely on a watch to determine heart rhythm. Period.
To the moderators, I would remove what appears to be an endorsement of a product that basically has no possibility of actually working and has potential to cause harm.

Im not a doctor and I dont play one on TV either. Sorry, had to get that line in there.
But, it'll be a cold day in the depths of hell when a watch band determines the status of electrical activity in my heart being OK or bad. No way. How do they test this out? Wait for people to hopefully have strokes and see if the watch picks up on it? Do tests on willing subjects that sign a waiver that says they dont mind if blood flow to their brain is stopped for a while?
I wonder too about legal ramifications that will undoubtedly stem from cases where the watch did NOT pick up on a heart problem and that person died because they didnt go get help. ChaaaChinggg $$$$$
Or, how about false positives? Sending people to ERs for what amounts to nothing.
I dunno.... this whole thng seems extremely suspect to me.
