Abstract: Primary recognition of heart diseases by exploiting computer-aided diagnosis (CAD) machines decreases the vast rate of fatality among cardiac patients. Recognition of heart abnormalities is a staggering task because the low changes in ECG signals may not be exactly specified with eyesight. In this paper, an efficient combination classification model using grasshopper optimisation algorithm (GOA) and support vector machines (SVMs) called GOA-SVM for ECG arrhythmia diagnosis is proposed. In this approach, the combination of discrete wavelet transform and higher-order statistics is used to feature extraction and the entropy-based feature selection method. The proposed method has been compared with PSO-SVMs and SVM-RBF kernel function for classifying the five classes of heartbeat categories. Our proposed system is able to classify the arrhythmia classes with high accuracy (99.66%). The simulation results show that classification accuracy in SVM-GOA method is better than SVM-RBF and neural network classifier.
