It can be used to diagnose the health of heart. A deep convolutional neural network(CNN)for single lead ECG,a special one-dimensional signal,was proposed in this paper. The proposed CNN was characterized by a very deep structure,multi-scale convolution kernels,and meanwhile a small parameter size. The proposed method can classify the first lead ECG heartbeats effectively. Firstly,preprocessed ECG data was imported into the network. Then,the classification results were exported through a series of convolution and pooling operation. This CNN was applied to the St. Petersburg Institute of Cardiological Technics 12-lead Arrhythmia Database(INCART). The classification experiments were carried out with more than 170 thousand first lead ECG data. The results obtained were: accuracy 98% ,sensitivity 90% and positive predictive value 86% . Experiment results show the proposed method can make a good classification of first lead ECG heartbeats. It can further apply in wearable devices and remote monitoring areas %K 第一导联 %K 心电图 %K 卷积神经网络 %K 可穿戴设备 %K 远程监护< %K br> %K first lead %K electrocardiogram %K convolutional neural networks %K wearable devices %K remote monitoring %U http://journals.tju.edu.cn/zrb/oa/darticle.aspx?type=view&id=201810001
