Abstract

This paper proposes an automatic paroxysmal atrial fibrillation(PAF)detection method based on grey information measurement. Firstly

the discrete wavelet transform(DWT)is applied to decompose an electrocardiogram(ECG)signal into sub-band signals. Then

the difference operation is used for wavelet coefficients to obtain the corresponding one-order central difference plot and gray histogram. Next

the variance

coefficient of variation

and Shannon entropy are extracted from the gray histogram to be the fusion features of atrial fibrillation ECG. Finally

PAF detection is completed automatically by integrating the extracted features with extreme learning machine(ELM). Experimental results on MIT-BIH database show that the average sensitivity

specificity and accuracy of the proposed method reach 93.7%

94.6% and 94.0%

respectively.
