The Apple Watch’s ECG Feature Is Finally Here. It’s Cool. Maybe Scary Too.

The point here is not that the watch can’t do a medical-grade ECG — it’s that it can do an ECG at all.

To those people I say this: It’s a fucking watch. The point here is not that the watch can’t do a medical-grade ECG — it’s that it can do an ECG at all.

If I had told you 10 years ago that your watch could perform an ECG good enough to win de novo clearance from the FDA you would have cried nonsense. You might even have cried nonsense five years ago — especially if I explained that the ECG circuit would be completed by touching the watch crown with a fingertip, allowing electrical signals across the heart to be measured.

Even if you didn’t dismiss this ridiculous idea of a heart watch back then, would you also have imagined that this device could make phone calls and stream music and give wrist tap directions and allow us to send crude and sometimes obscene fingertip drawings to other people with the same watch? I mean, I don’t think you would have? Sorry.
