Samsung Galaxy Watch 6 Can Predict Vasovagal Syncope Fainting with High Accuracy
Partnership with Korean Hospital Develops AI-Powered Biosignal Analysis for Early Warnings
Quick Look
Samsung's Galaxy Watch 6, in a study with Chung-Ang University Gwangmyeong Hospital, predicts vasovagal syncope (VVS) fainting with 84.6% accuracy up to 5 minutes in advance using AI-analyzed PPG sensor data, potentially preventing severe secondary injuries.

Why It Matters
Vasovagal syncope affects up to 40% of people, often triggered by emotional distress or sight of blood.
The most common type of fainting, vasovagal syncope (VVS), can now be predicted with high accuracy by Samsung’s Galaxy Watch 6, according to a recent study. This breakthrough could prevent severe injuries from falls.
Samsung collaborated with Chung-Ang University Gwangmyeong Hospital in Korea, detailing their method in the European Heart Journal. VVS occurs when heart rate and blood pressure drop abruptly, often triggered by stress or the sight of blood, affecting up to 40% of people.
The study involved 132 patients undergoing induced fainting tests. Using the watch’s PPG sensor and an AI algorithm, the team achieved 84.6% prediction accuracy up to five minutes before fainting, with 90% sensitivity and 64% specificity.
"This shifts healthcare from post-care to preventive care," said Jongmin Choi, Samsung’s Health R&D Head. The company claims this as a "world-first" in fainting prediction technology.
