The New ECG Apple Watch Could Do More Harm Than Good

Why would someone use an ECG if they're not experiencing any symptoms? I've had an ECG twice in my life - as it turned out both times were a result of panic attacks. But I also have a family history of heart issues. Meanwhile I have a friend who suffers from AFib and this could be an invaluable tool for him.

I guess the bottom line is this isn't a toy, it's a medical device used to provide important diagnostics for potentially serious medical situations. I trust people would treat it as such.
