Samsung Electronics said on Wednesday it became the first in the world to prove through a joint clinical study with Chung-Ang University Gwangmyeong Hospital that a Galaxy Watch can predict vasovagal syncope at an early stage. The results were published in the latest issue of European Heart Journal-Digital Health, a digital health journal published by the European Society of Cardiology. The study analysed real-time heart rate variability data collected by the Galaxy Watch6 and predicted signs of syncope about 5 minutes in advance with 84.6 percent accuracy.
