Samsung Electronics Co., Ltd. today announced that a joint clinical study with Chung-Ang University Gwangmyeong Hospital in Korea has successfully validated the ability to predict vasovagal syncope (VVS) with high accuracy by utilizing biosignals obtained from Galaxy Watch6.<\/p>\n
\u00a0<\/p>\n
Vasovagal syncope occurs when a person\u2019s heart rate and blood pressure drop abruptly due to factors like excessive stress, leading to a temporary loss of consciousness. While the fainting spell itself is typically not life-threatening, sudden falls can cause severe secondary injuries like fractures or concussions, making early prediction critically important for prevention.<\/p>\n
\u00a0<\/p>\n
\u201cUp to 40% of people experience vasovagal syncope over their lifetime, with one-third experiencing recurrent episodes,\u201d said Professor Junhwan Cho of the Department of Cardiology at Chung-Ang University Gwangmyeong Hospital. \u201cAn 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.\u201d<\/p>\n
\u00a0<\/p>\n
The joint research team, led by Professor Cho, conducted evaluations on 132 patients with suspected VVS symptoms during induced fainting tests. Using a Galaxy Watch equipped with a photoplethysmography (PPG) sensor[1]<\/a>, the team analyzed the watch\u2019s heart rate variability (HRV) data with an AI algorithm. The model successfully predicted impending fainting\u00a0episodes\u00a0up to five minutes in advance with\u00a084.6 percent accuracy, at a clinically meaningful sensitivity of 90 percent and a specificity of 64 percent.<\/p>\n \u00a0<\/p>\n \u201cThis study is an example of how wearable technology can help shift healthcare from being designed for \u2018post-care\u2019 to a model of \u2018preventive care,\u2019\u201d said Jongmin Choi, Head of Health R&D Group, Mobile eXperience (MX) Business, Samsung Electronics. \u201cWe are committed to driving technological innovation that empowers our users to lead healthier everyday lives.\u201d<\/p>\n \u00a0<\/p>\n
