Samsung's Galaxy Watch 6 achieved 84.6% accuracy in predicting vasovagal syncope up to five minutes before it happens in a clinical study with 132 patients. The wearable technology uses a photoplethysmography sensor and AI algorithm to analyze heart rate variability. But medical experts warn the 64% specificity could trigger excessive false alarms in real-world use.
Samsung Galaxy Watch Demonstrates Ability to Predict Fainting Episodes
Samsung has released findings from a clinical study showing its Galaxy Watch 6 can predict fainting episodes with 84.6% accuracy using an AI algorithm and biosignals

. The research, conducted in partnership with Chung-Ang University Gwangmyeong Hospital in Korea, evaluated 132 patients with suspected vasovagal syncope symptoms during induced fainting tests4
. The Samsung Galaxy Watch successfully predicted fainting episodes up to five minutes in advance, achieving a clinical sensitivity of 90% and specificity of 64%1

The wearable technology uses a photoplethysmography sensor, or PPG sensor, which measures changes in blood flow beneath the skin using light

. By analyzing heart rate variability data collected through this sensor, the AI algorithm identifies patterns that emerge before someone faints5
. The findings were published in European Heart Journal - Digital Health, with Samsung calling it a "world-first breakthrough in fainting prediction"4
.Understanding Vasovagal Syncope and Its Risks
Vasovagal syncope affects up to 40% of people throughout their lives, according to Professor Junhwan Cho from Chung-Ang University Gwangmyeong Hospital

. This common type of fainting occurs when heart rate and blood pressure drop abruptly, often triggered by stress, dehydration, standing too long, or emotional distress2
. While the fainting itself is rarely life-threatening, secondary injuries from falls can cause concussions, fractures, or blood loss3

"An early warning could give patients advance time to get into a safe position or call for help, which would dramatically reduce the incidence of secondary injuries," Professor Cho explained

. Dr. Sam Setareh, director of cardiology at Beverly Hills Cardiovascular and Longevity Institute, echoed this view: "Even a few minutes of warning could be meaningful: sit or lie down, hydrate, perform counterpressure maneuvers, or call for help. That could reduce falls, fractures, concussions, and other secondary injuries"2
.Medical Experts Highlight Significant Limitations
Despite the promising results, medical professionals have raised concerns about the study's limitations and real-world applicability. Dr. Brett A. Sealove, chair of cardiology at Hackensack Meridian Jersey Shore University Medical Center, identified the 64% specificity as one of the biggest issues
2
. "In a controlled tilt-table lab, that may be acceptable," he said, "but in the real world, where millions of watch users are moving through daily life, that false-positive rate could generate an enormous volume of unnecessary alerts"2
.The clinical study was conducted in a highly controlled environment with patients undergoing tilt-table testing specifically designed to provoke fainting episodes
2
. Dr. Setareh cautioned that everyday factors such as motion artifact, hydration status, posture, medications, sleep, alcohol, and anxiety can all affect biosignals in real-world settings2
. "Too many false positives can create anxiety, alarm fatigue, and unnecessary medical evaluations," he warned2
.Dr. Sealove also noted that all participants had suspected neurally mediated syncope and were undergoing a deliberately provocative laboratory procedure. "The study tells us nothing about how this algorithm would perform in someone who has never had a tilt-table test, who has no documented history of vasovagal syncope, or who is simply going about their daily life," he said
