World First: Samsung Galaxy Watch Achieves Early Prediction of Fainting Spells
Samsung has announced a groundbreaking achievement in wearable health technology. A joint clinical study with Chung-Ang University Gwangmyeong Hospital in South Korea has successfully validated that biosignals from the Galaxy Watch 6 can predict vasovagal syncope (VVS) with high precision.
Vasovagal syncope occurs when factors like excessive stress cause a sudden drop in a person's heart rate and blood pressure, leading to a temporary loss of consciousness. While the fainting spell itself is typically not life-threatening, the resulting fall can cause severe secondary injuries such as fractures or concussions. Therefore, early prediction is crucial for prevention.
"As many as 40% of people will experience vasovagal syncope in their lifetime, and a third of them will have recurrent episodes," said Professor Junhwan Cho of the Cardiovascular Medicine department at Chung-Ang University Gwangmyeong Hospital. "An early warning can give patients enough time to assume a safe posture or seek help, which will significantly reduce the incidence of secondary injuries."
The joint research team, led by Professor Junhwan Cho, evaluated 132 patients with suspected VVS symptoms during a syncope induction test. Using a Galaxy Watch equipped with a photoplethysmography (PPG) sensor, the team's AI algorithm analyzed the watch's heart rate variability (HRV) data. The model successfully predicted impending fainting events five minutes in advance with an accuracy rate of 84.6%.
This pioneering research was published in the medical journal *European Heart Journal – Digital Health*, representing the world's first successful demonstration of a commercial smartwatch's potential to predict fainting spells ahead of time.
Looking ahead, Samsung plans to further enhance the health monitoring capabilities across its portfolio of wearable devices and expand its collaborations with leading medical institutions to continue pushing the boundaries of digital health.
