Samsung says it has developed a new health-monitoring feature for the Samsung Galaxy Watch 6 that could help predict fainting episodes before they occur. The feature was tested in a joint clinical study with Chung-Ang University Gwangmyeong Hospital, where researchers evaluated the smartwatch’s ability to detect signs of vasovagal syncope (VVS), a condition caused by a sudden drop in heart rate and blood pressure. Samsung says early warnings could help users avoid injuries caused by sudden falls.

The clinical study suggests that the Samsung Galaxy Watch 6 may be capable of predicting fainting episodes before they occur. According to Professor Junhwan Cho, up to 40 percent of people experience vasovagal syncope (VVS) at some point in their lives, while nearly one-third face recurring episodes. The condition is caused by a sudden drop in heart rate and blood pressure, often leading to unexpected fainting.

The study found that the smartwatch used its photoplethysmography (PPG) sensor, which monitors blood circulation changes, along with heart rate variability data and an AI-powered algorithm to detect early signs of fainting. Researchers tested the system on 132 patients during induced fainting tests, and Samsung claims the technology achieved an accuracy rate of 84.6 percent while predicting episodes up to five minutes in advance.
Samsung says the feature could help shift healthcare from reactive treatment to preventive care. According to Jongmin Choi, wearable devices may eventually help users identify health risks before medical emergencies happen. Early alerts could allow people to sit down, seek assistance, or avoid serious injuries such as fractures and concussions caused by sudden falls.
Although Samsung has not confirmed a public rollout timeline for the feature, the company says it plans to continue improving health-monitoring capabilities through partnerships with medical institutions. The Samsung Galaxy Watch 6, launched in India in 2023, already includes several health tools such as heart rate tracking, blood oxygen monitoring, sleep tracking, and AFib detection for irregular heart rhythms.
