Reddit:

I’m an Emergency Physician and read/interpret ECGs on a daily basis. I wanted to talk about the Apple Watch’s new ECG feature as there are a lot of misconceptions about this new function. Apple Watch’s new ECG feature is pretty neat and a lot of people here are understandably excited about it, but it does have limitations.

The new Apple Watch looks like a great tool, but it is not meant to be a medical grade device and not a substitute for medical and professional evaluation in the case of symptoms. Even if your Apple Watch ECG appears totally normal that does not necessarily mean you do not have atrial fibrillation or other cardiac abnormalities.

I’m by no means an expert in this kind of thing but this seems like good, common sense information. Any doctors in the audience who can confirm or refute any of the statements made in this Reddit post?
