摘要
为了更准确地检测心律失常,提出基于单心搏活动特征与BiLSTM-Attention模型的心律失常检测方法。采用MIT-BIH心律失常数据库对算法进行验证,用双正交小波变换去除噪声干扰;通过二进样条小波变换的模极大极小值对检测R波峰值位置,并提取QRS波群数据及RR间期;使用BiLSTM-Attention分类模型进行心搏识别。实验结果表明,N、S、V和F类心搏的灵敏度分别为99.76%、94.74%、97.53%、83.93%,阳性预测值分别为99.76%、94.03%、97.53%、87.04%,F1综合指标达到了99.40%,证明了该算法的有效性。
In order to detect arrhythmia more accurately,this paper proposed arrhythmia detection method based on single heartbeat activity characteristics and BiLSTM-Attention model.We used MIT-BIH arrhythmia database to verify the algorithm,and biorthogonal wavelet transform was used to remove noise interference.Then,the peak position of R-wave was detected by the modulus minimax value pairs of binary spline wavelet transform,and we extracted QRS wave group data and RR interval.Finally,the BiLSTM-Attention classification model was used for heartbeat recognition.The experimental results show that the sensitivity of N,S,V and F type beats are 99.76%,94.74%,97.53%,83.93%,the positive predictive value are 99.76%,94.03%,97.53%,87.04%,and the comprehensive index of F1 reaches 99.40%,which proves the effectiveness of the proposed algorithm.
