A clinical study shows Samsung Galaxy Watch6 can predict fainting episodes with 84.6% accuracy, warning users up to 5 minutes in advance using AI analysis of heart rate variability.
Samsung has announced the results of a clinical study in which the Galaxy Watch6 demonstrated the ability to predict fainting episodes. The research was conducted in collaboration with Chung-Ang University Hospital in South Korea.
The study focused on vasovagal syncope, one of the most common causes of fainting. This condition occurs when heart rate and blood pressure drop sharply, temporarily reducing blood flow to the brain.
In the experiment, 132 patients with suspected syncope episodes underwent tests under medical supervision while wearing the Galaxy Watch6. The watch collected physiological data using photoplethysmography and analyzed heart rate variability. An artificial intelligence system then processed the information.
Results showed that the device could warn users approximately five minutes before a potential fainting event. Overall prediction accuracy was 84.6%, with sensitivity at 90% and specificity at 64%.
Researchers stated that such warnings could give individuals time to assume a safe position or call for help, which is especially important for preventing fall-related injuries.
Samsung Electronics noted that this is one of the first successful demonstrations of a commercially available wearable device predicting such conditions.
The company also plans to develop preventive medicine features in future Galaxy devices, focusing on artificial intelligence for early risk detection.
