Cardiomatics and the Medical University of Warsaw are collaborating to develop Cardiomatics Junior, an innovative tool for automatic assessment of ECG signals in children. By utilizing AI-based algorithms, this project aims to revolutionize paediatric cardiology diagnostics, potentially reducing analysis time to 5 minutes and improving accessibility to Holter monitor testing for young patients. Supported by the National Centre for Research and Development, this groundbreaking initiative will benefit physicians, Holter monitor manufacturers, and clinical trial implementers, ultimately enhancing diagnosis and treatment of paediatric heart conditions.
