Samsung and Chung-Ang University Gwangmyeong Hospital have successfully demonstrated that the Galaxy Watch6 can predict vasovagal syncope, or fainting, several minutes before it happens, according to TechPinas . The study achieved 84.6 percent accuracy in clinical evaluations involving patients with suspected symptoms.
Researchers combined heart rate variability data from the Galaxy Watch6's PPG sensor with AI-powered analysis to detect impending fainting episodes. The wearable monitors biosignals in real time, offering a potential early warning system for sudden loss of consciousness.
Samsung describes the finding as the world's first successful demonstration of a commercial smartwatch for early syncope prediction. The development reinforces the company's push toward personalized and preventive healthcare through wearable technology, which could help users avoid dangerous situations such as falls while driving or climbing stairs.
