A Shallow Neural Network Approach for ECG Arrhythmia Detection Using Feature-Based Classification

, Ebby Darney P

The process of Electrocardiogram (ECG) arrhythmia detection provide an important role in the detection of heart diseases at an early stage. In the proposed work, a Shallow Neural Network (SNN) is used for ECG arrhythmia detection. During the data preprocessing stage, raw ECG signals undergo noise removal, followed by the application of Band Pass Filter (BPF), Wavelet denoising to enhance the quality of the signal, Z-score normalization is used for normalizing the amplitude of the signal, R-peak detection method is performed to accurately identify the locations of R-peaks. In the segmentation stage, the detected R-peaks are used to perform fixed-window segmentation and segments the continuous ECG into individual cardiac segments of equal length. The segmented ECG signals are used as direct input to the SNN during the classification stage, where it learns the signal pattern characteristics and classifies them as normal or arrhythmic patterns, resulting in an automated ECG arrhythmia detection framework. ECG arrhythmia classification dataset is used and this system is implemented in Python software and achieves accuracy of 98.88%, 98.84% precision, 98.88% recall and 98.84% F1-score.
