The Modular ECG Analysis System (MEANS) has a long‑standing modular architecture that has evolved over 20 years with continuous updates to its modules. The study aims to highlight the benefits of a modular design for ECG decision‑support systems, emphasizing easier maintenance and independent module optimization. MEANS is built from signal‑analysis and diagnostic‑classification modules, and its performance was evaluated in the CSE study. The evaluation shows performance results for individual modules and the overall system.
The methodology, used in the Modular ECG Analysis System (MEANS) is described. MEANS consists of modules for signal analysis and diagnostic classification. The basic structure of the modular interpretation system remained intact over a period of 20 years, while all modules underwent many changes as a function of experience and insight, and the continuously changing information technology. The article describes the advantages of a modular approach to decision-support systems, the most important ones being easier maintenance of the software package and separate optimization and testing of each module. The overall evaluation of MEANS was done in the CSE study. Evaluation results for modules and for the entire system are presented.
