- The Apple Heart Study, conducted by Stanford University researchers and sponsored by Apple, evaluated the ability of the Apple Watch to detect atrial fibrillation, a common heart disorder also known as A-fib, in an astonishing 400,000 participants.
- The study was not a randomized controlled trial, the gold standard of medical research.
- It’s a purely observational study designed to see whether the Apple Watch’s heart pulse monitor can identify people who have a-fib.
- A leading cardiologist told me “the study is really moot and doesn’t change my views on the Apple watch for patients”
