On May 7, 2023, Samsung announced a significant advancement with its Galaxy Watch6, claiming it can predict fainting episodes due to vasovagal syncope (VVS) up to five minutes in advance. This prediction capability was validated in a clinical study conducted in collaboration with Chung-Ang University Gwangmyeong Hospital, where researchers analyzed data from 132 patients using the watch's photoplethysmography (PPG) sensor. The study revealed an impressive 84.6% accuracy in predicting fainting episodes, which could potentially help users avoid falls and injuries associated with sudden loss of consciousness. Professor Junhwan Cho from the hospital emphasized that early warnings could enable individuals to seek safety or assistance, as VVS affects up to 40% of people. Samsung's head of Health R&D, Jongmin Choi, highlighted the shift towards preventive healthcare through wearable technology and indicated plans to further collaborate with medical institutions for personalized health solutions. The findings were published in the European Heart Journal-Digital Health.
