A 132-patient clinical study with Chung-Ang University Gwangmyeong Hospital found Galaxy Watch6 predicted episodes about five minutes in advance with 84.6% accuracy.
Researchers used the watch's PPG sensor to track heart rate variability during head-up tilt tests and analysed the data with an AI algorithm.
The findings, published in European Heart Journal-Digital Health, mark the first reported smartwatch prediction of syncope and could help users take protective action before fainting.

Samsung Galaxy Watch6 Predicts Vasovagal Syncope with 84.6% Accuracy Up to 5 Minutes Before Onset
Overview
In 2026, Samsung Electronics and Chung-Ang University Gwangmyeong Hospital conducted a clinical study validating the Galaxy Watch6's ability to predict vasovagal syncope (VVS) with 84.6% accuracy and up to five minutes' advance warning. The watch uses a photoplethysmography sensor to capture heart rate variability, analyzed by advanced AI algorithms to detect early signs of fainting. When an impending episode is detected, the watch alerts users through vibrations, sounds, and visuals, enabling preventive actions like sitting or lying down to avoid injuries. This feature integrates into Samsung's broader health ecosystem and reflects the company's vision to transform healthcare from reactive to proactive, while acknowledging limitations such as false positives and the need for medical oversight.
