Undiagnosed atrial fibrillation (AF) increases the risk of stroke five-fold. AF related strokes can be prevented through earlier detection and timely treatment. ¹

Better and faster methods of detecting AF are needed.

The C3⁺ offers a faster and easier way of screening your patients for arrhythmia. The C3⁺ records high quality 3 channel ECG, is lightweight, reusable and has 7 days of battery life. Cable-free and attached to the patient using standard electrodes, the C3⁺ offers a truly frictionless Holter Monitoring experience. Additionally, the C3⁺ integrates with multiple third-party analysis software solutions, both stand alone and cloud based.


Using the Cortrium Cloud, we offer automated, AI based reporting to support the diagnosis. The C3⁺ is compatible with a variety of local healthcare applications.


Cortrium collaborates with Cardiomatics to offer automated, AI-based reports. The algorithms are certified according to EN 60601-2-47 and ensure a sensitivity of 99.97% of detecting ventricular beats and 93.00% of detecting episodes of atrial fibrillation (based on MIT-BH database). ²
