So I’ve been having a fluttering feeling in my chest and I’ve been trying to catch something for weeks. Finally felt it while running the ECG, But the question is, how accurate is it? I am scheduled to see a cardiologist, but I’m afraid it won’t be doing anything during my tests
It's been medically proven to be equivalent to a single-wire EKG. It's been proven to enough of a degree that it's the one health feature that is FDA approved and Apple can actually claim as a medical feature.
However, single-wire EKGs are the least accurate and relied-upon. Your doctor may look at the data, but they'll definitely do their own EKG, and it won't be single-wire.
