What the Apple Watch’s heart-health upgrade means

Here’s a nice explainer from CNBC’s Christina Farr about what the EKG features in the new Apple Watch mean, including the difference between FDA “approval” and FDA “clearance.”

I’ve noticed a lot of discussion from people connected to the medical industry regarding this feature in the last day. Some people really do believe that this could be a huge step forward in terms of diagnosing heart problems and saving lifes; other think it will generate a huge number of false-positive results that will lead to unnecessary doctor appointments and ER visits.
