CART (CARdio-Tracker)


Ring-type medical device that continuously monitors atrial fibrillation and heart rate using PPG and ECG signals.

For AF patients, CART can provide heart rate, AF episode and AF burden(%) to prevent various complications related to AF such as heart failure, blood clots, heart attack and dementia. 




1. Ring-type wearable medical device

  • World's first wearable ring certified as medical-grade
  • MFDS and CE MDD have approved
  • Simple and easy to wear 24/7

2. Continuous heart monitoring with 99.6% diagnostic accuracy

  • Offer two complementary ways to measure your HR and pulse 
    - Background check : continuous monitoring using PPG signals
    - Self check : double check using ECG as a gold standard together with PPG signals if you feel the symptoms
  • AF burden(%) is measured as well as AF episodes.
  • 99.6% diagnostic accuracy with Deep learning algorithms
