WASHINGTON — A huge study suggests the Apple Watch can detect a worrisome irregular heartbeat at least sometimes — but experts say more work is needed to tell if using wearable technology to screen for heart problems really helps. More than 419,000 Apple Watch users signed up for the unusual study, making it the largest ever to explore screening seemingly healthy people for atrial fibrillation, a condition that if untreated eventually can trigger strokes. Other cardiac experts said the study, which was funded by Apple, suggests screening with wearable technology might be technically feasible eventually, but needs lots more research. HOW DOES THE APPLE WATCH CHECK FOR IT? The latest version of the Apple Watch also allows wearers to push a button to take an EKG and share the reading with doctors.
