Introduction CS System 3 is a wrist-worn medical device, similar to a watch, that measures heart rate, Pulse Rate and detects atrial fibrillation (A-Fib) by reading the user’s PPG and ECG values. CS System 3 comprises a watch (CS Watch 3), a charging cradle, a mobile application (CS3 Mobile app), and a cloud application (CS3 Cloud app).
5 minutes by using PPG and/or ECG signals. Intended Users CS System 3 is intended to be used by anyone who seeks to monitor their vital signs in medical facilities, ambulatory conditions, or at home. The device is intended as a single patient use.
To protect your privacy, the reports that are created through the mobile app are stored only on your smartphone. For subscribers, the reports are automatically stored in CS Cloud App. CardiacSense recommends locking your smartphone’s display to avoid unauthorized access.

Appendices Medical Terms A.1. About A-Fib A-Fib is a reentrant cardiac arrhythmia marked by rapid randomized contractions of the atrial myocardium, causing an irregular, rapid atrial rate. It is recognizable on an electrocardiogram by the absence of P waves and an irregular ventricular response. A-Fib is an independent risk factor for stroke and thromboembolism that cause mortality.
