"Samsung said the system was able to detect warning signs up to five minutes before a fainting episode, with an overall accuracy of 84.6 percent. The model also recorded a sensitivity of 90 percent and a specificity of 64 percent."
"The study involved 132 patients with suspected vasovagal syncope symptoms who underwent induced fainting evaluations under medical supervision. Participants wore a Galaxy Watch 6 equipped with a photoplethysmography sensor that monitored heart rate variability data throughout the tests."
"Samsung explained that vasovagal syncope can be triggered by factors such as stress, pain, fear, or emotional strain. While the condition itself is usually not life-threatening, sudden falls caused by fainting can lead to injuries including fractures, concussions, or head trauma."
Samsung conducted a clinical study with Chung-Ang University Gwangmyeong Hospital demonstrating that wearable devices can predict fainting episodes caused by vasovagal syncope. The study involved 132 patients wearing Galaxy Watch 6 devices equipped with photoplethysmography sensors to monitor heart rate variability during induced fainting evaluations. An AI-based prediction model analyzed the collected biosignal data and detected warning signs up to five minutes before fainting episodes with 84.6% accuracy, 90% sensitivity, and 64% specificity. Vasovagal syncope involves sudden drops in heart rate and blood pressure triggered by stress, pain, fear, or emotional strain. While the condition is typically not life-threatening, fainting-related falls can cause serious injuries including fractures and head trauma. This represents the first successful demonstration of fainting prediction using a commercial smartwatch.
