Design and implementation of a multifunctional ECG analysis software system

With the popularization of computer technology and the development of signal processing technology, the computer automatic diagnosis of ECG has entered the practical stage. In this paper, a multi-functional ECG analysis software system is designed and implemented, which can read and analyze ECG signals and draw ECG waveforms, calculate ECG parameters such as heart rate (HR), P wave time and RR interval, and draw corresponding diagnostic conclusions. C# was used as programming language in Windows and WPF framework for software development. Software design based on model-View-Controller (MVC) framework; Access ECG data to disk through file IO operation; the ECG data of 40 patients were processed and analyzed, and the results were compared with doctors' diagnosis results. After testing, the software system can run stably on PC. The accuracy of the calculation of the relevant parameters of 40 sets of data is above 95%, and the accuracy of the interpretation of normal ECG is above 98%. The accuracy rate of arrhythmia detection is over 90%. This ECG analysis software system has certain clinical application value.
