The sensors in the watch can be used to analyze pulse data. When the sensors detect large variations in heartbeats over a 48-hour period, it will send out an alert. In one Stanford study, over 419,000 Apple Watch wearers shared their heart data with researchers.
A third of the participants were diagnosed with atrial fibrillation. Experts say wearable tech screenings may become successful over time, but need more research.
