Simplify Continuous Cardiac Monitoring With The Corsano Bracelet

The CardioWatch 287 Bracelet

The activity and heart rate monitor of Corsano CardioWatch consists of an accelerometer and a photoplethysmogram (PPG) sensor. The PPG sensor consists of an LED and a photodiode and measures fluctuations in the light reflected from the arteries and arterioles in the subcutaneous tissue. From the light fluctuations measured the actual heart rate and potential cardiac arrhythmias can be detected. In addition to the PPG sensor the accelerometer provides data on the activity level of the wearer of the bracelet.

Corsano CardioWatch not only analyses your heartbeat, but also and especially your heart rhythm – simple and at any time. The A-Fib algorithm has been validated in clinical studies and detects irregular heartbeats (e.g. extrasystoles) as well as the presence of absolute arrhythmia with suspected atrial fibrillation (AF).

The bracelet monitor offers flexibility to set data collection intervals by minute, by second or 25Hz. We measure Heart Rate, RR intervals, Breathing Rate, A-Fib detection, Skin Temperature, Activity and Sleep. SpO2, Core Body Temperature, ECG and Blood Pressure are in development.  Click on image to download the relevant CardioWatch 287 leaflet.

The App

The Corsano app provides seamless integration with Preventicus Heartbeats, a CE Class IIa certified medical device to analyse your heartbeat, but also and especially your heart rhythm. 

Using the PPG sensor in the bracelet, a pulse curve is captured continuously, and the heart rate data derived. If any evidence of arrhythmia is found, the user can store the underlying information in a measurement report. The user is also recommended to undergo further medical assessment by professionals.Preventicus has verified the detection of atrial fibrillation and extrasystoles and the accuracy of the heart rate detected with in-house clinical studies (see also: These have shown that the underlying algorithm of the app can distinguish between atrial fibrillation and a regular heart rhythm with an accuracy of more than 96%. 


The purpose of Preventicus Heartbeats is to detect signs of the presence of cardiac arrhythmias in a non-clinical environment. This includes the following cardiac arrhythmias: detection of signs of absolute arrhythmia with suspected atrial fibrillation, detection of signs of extrasystoles as well as measuring the heart rate with signs of bradycardia and tachycardia without further diagnostic differentiation.

1)     Summarised results of the heart rhythm analysis
2)     Heart rate in beats per minute (bpm) over the entire measurement
3)     The original pulse curve.

Cardiac arrhythmias such as atrial fibrillation often occur only occasionally and can therefore be difficult to prove in the doctor’s office. Therefore, screening for cardiac arrhythmia by regular measurements of the heart rhythm is a precautionary measure for heart attack prevention recommended by cardiological societies.
