In this paper, a support vector machine (SVM) approach using statistical features, P wave absence, spectrum and length-adaptive entropy are presented to classify ECG rhythms as four types: normal rhythm, atrial fibrillation (AF), other too noisy classify.The proposed algorithm consisted of three steps: (1) signal pre-processing based on the wavelet method; (2) feature extraction, extracted features including one power feature, two 17 RR interval-related 11 features; (3) classification SVM...
