A Robust Method to Reliable Cardiac QRS Complex Detection Based on Shannon Energy and Teager Energy Operator

摘要

The QRS complex is considered to be one of the main factors in diagnosing heart diseases; thus, its detection on the electrocardiogram signals has become the target of various types of research. The primary aim of this study is to design and develop a novel technique for QRS complex detection under various ECG signal morphologies and different QRS waveforms. In this study, we report an algorithm for detecting the QRS complex using the Shannon energy (SE) and Teager energy operator (TEO) to obtain valid QRS on ECG signals. In this scheme, the first stage includes SE and band-pass filter for QRS complex localization. Next, the novel process of R-peak detection based on TEO to create a smoothed detection mask is considered. Finally, the proposed method's performance and validity are tested on the Massachusetts Institute of Technology-Beth Israel Hospital arrhythmia database. To this end, a highly accurate, quick, and simple mathematical operation is provided based on SE and TEO, with baseline threshold and minimum lag. The efficiency of the undertaken method for detecting the QRS complex compared to recent state-of-the-art methods shows an accuracy of 99.829%. Also, the proposed approach is designed with three quick and straightforward stages by low computational time complexity for setting up and applying reliable cardiac QRS detection.
