Our diagnostic software platform is aimed at revolutionizing heart care by providing clinicians worldwide with seamless access to AI diagnostics for electrocardiograms (ECGs). We are committed to keeping the healthcare system affordable and sustainable by timely diagnosis of heart disease using reliable ECG diagnostics close to patients.

Timely and more accurate detection of heart disease

The AI-powered software platform for electrocardiogram analysis developed by Cordys Analytics offers a new and innovative solution for healthcare professionals to detect heart disease earlier and more accurately. By harnessing the power of advanced deep learning techniques, this software enhances the diagnostic process by identifying subtle patterns and abnormalities in electrocardiogram data that might not be easily discernible through traditional methods. The software provides valuable new insights and supports healthcare professionals in making informed decisions.

A sustainable healthcare system

By enabling early detection, prevention, and more efficient diagnosis, AI-powered ECG software has the potential to reduce overall healthcare costs by minimising hospitalizations and complications associated with untreated heart conditions. With the software from Cordys Analytics, doctors and other healthcare professionals can detect heart disease earlier and more effectively, preventing unnecessary casualties and high treatment costs in the healthcare system, while improving the quality of life for patients with a heart condition.

AI algorithms integrated in clinician's workflow

Our software's vendor-agnostic nature allows it to seamlessly connect various healthcare organisations and ECG devices, making it a versatile tool for healthcare professionals working in different clinical settings and regions around the world. Its cloud-based architecture provides operational benefits, such as real-time data analysis, remote accessibility and scalability.

About Us

Cordys Analytics is a spin-out company that originates from the University Medical Center Utrecht. It focuses on using AI-powered algorithms to detect heart disease from electrocardiograms (ECGs).

Our research activities began in 2018 at the University Medical Center Utrecht (UMCU) in the Netherlands by René van Es, associate professor in the cardiology department, and Rutger van de Leur, a medical doctor and PhD student. The primary goal of our research was to develop AI-powered algorithms for the detection of heart disease from 12-lead electrocardiograms (ECGs). We collaborated with the UMCU's cardiovascular group to create top-notch machine learning algorithms. The UMCU provided a valuable resource of more than 1.5 million annotated ECGs. This dataset was used to train and validate machine learning algorithms, enabling the development of tools that outperformed the existing software in ECG devices.

In 2023 our team, which now included John van den Berg as CEO, successfully created and funded Cordys Analytics as a spin-out company. In the same year Cordys Analytics entered into a long-term collaboration agreement with the University Medical Center Utrecht, strengthening its ties with the institution where it originated.

The team at Cordys Analytics brings together clinicians, engineers and data scientists, enabling our company to drive innovation in the field of heart care. Cordys Analytics represents a successful example of translating academic research into practical applications with the potential to truly improve healthcare outcomes.
