The study started with 767,338 patients with clinical notes.

Out of that haystack, only 41 referred to an Apple Watch alert about abnormal pulse detection.

And of that 7 were found to have enough concern to further explore potential cardiovascular disease.

So, out of three quarters of a million visits, there were 41 with concerns from an Apple Watch, and 7 people received early treatment they might not have otherwise received (which could potentially save millions of dollars of future healthcare costs).

34 people were false positives and inconvenienced with a doctor's visit.

This seems like a net positive.
