Samsung says its Galaxy Watch6 can detect warning signs that a person may faint and provide alerts before an episode occurs. Several outlets report that the company points to results from a joint clinical study conducted with Chung-Ang University Gwangmyeong Hospital in South Korea. The watch uses biosignals, including heart-rate-related data and heart-rate variability, combined with artificial intelligence to identify patterns associated with vasovagal syncope (VVS). VVS is described as a fainting event that happens when heart rate and blood pressure drop abruptly, sometimes triggered by stress or other factors. Samsung and the reporting outlets say the approach can identify risk “several minutes in advance,” potentially helping users take safety measures such as getting into a safe position or contacting help. CNET and ZDNet also note that while the study is presented as promising, there are caveats and limitations that could affect real-world performance. Overall, the coverage frames the feature as an early-warning health monitoring capability aimed at reducing injury risk from sudden falls, rather than treating the underlying cause of fainting.
