CART-I

CART-I is a ring-typed medical device that continuously monitors Atrial
Fibrillation using ECG and PPG signals. It can be used by patients who are
diagnosed with or suspected of Atrial Fibrillation.
CART-I detects Atrial Fibrillation by recording the user’s pulse and
electrocardiogram, analyzes the collected signals through a programmed
algorithm and presents the results on the application.
The accuracy of CART-I’s Atrial Fibrillation detection has been clinically
proven. It consists of a medical grade application and website.

How to find the perfect size
▪When you purchase CART-I, we will send you a sizing kit first.
▪In the sizing kit, there are 8 different sizes of ring mock-up.
▪We recommend you use your index, middle or ring finger.
▪If the ring is too tight it will put pressure on your blood vessels. This will make
harder for CART to monitor your heart accurately.
▪If the ring is too loose, CART cannot monitor your signal accurately.
▪Once you have found the correct size, try wearing it for 24 hours night and day.
▪With the right sized CART, you are now ready to watch our “How to use CART”
video for more information on using CART.
