摘要
异常心电图(ECG)信号的早期诊断可为心律失常疾病的预防和检测提供有用信息。由于正常搏动(N)和室上性早搏(S)类别的相似性以及心电图类别的不平衡性,心律失常分类在患者间评估范式下无法达到令人满意的分类结果。本文提出了一种用于心律失常分类的多路径并行深度卷积神经网络。此外,还引入了全局平均 RR 区间来解决 N 类与 S 类之间的相似性问题,并开发了加权损失函数,根据输入批次中各类别所占比例动态调整权重来解决不平衡问题。MIT-BIH 心律失常数据集用于验证所提方法的分类性能。在患者内评价范式和患者间评价范式下的实验结果表明,与其他方法相比,提出的方法能取得更好的分类效果。其中,病例内评价范式下的准确率、平均灵敏度、平均精确度和平均特异度分别为 98.73%、94.89%、89.38% 和 98.24%。在患者间范式下,准确度、平均灵敏度、平均精确度和平均特异度分别为 91.22%、89.91%、68.23% 和 95.23%。
Arrhythmia classification based on multi-feature multi-path parallel deep convolutional neural networks and improved focal loss.
Early diagnosis of abnormal electrocardiogram (ECG) signals can provide useful information for the prevention and detection of arrhythmia diseases. Due to the similarities in Normal beat (N) and Supraventricular Premature Beat (S) categories and imbalance of ECG categories, arrhythmia classification cannot achieve satisfactory classification results under the inter-patient assessment paradigm. In this paper, a multi-path parallel deep convolutional neural network was proposed for arrhythmia classification. Furthermore, a global average RR interval was introduced to address the issue of similarities between N vs. S categories, and a weighted loss function was developed to solve the imbalance problem using the dynamically adjusted weights based on the proportion of each class in the input batch. The MIT-BIH arrhythmia dataset was used to validate the classification performances of the proposed method. Experimental results under the intra-patient evaluation paradigm and inter-patient evaluation paradigm showed that the proposed method could achieve better classification results than other methods. Among them, the accuracy, average sensitivity, average precision, and average specificity under the intra-patient paradigm were 98.73%, 94.89%, 89.38%, and 98.24%, respectively. The accuracy, average sensitivity, average precision, and average specificity under the inter-patient paradigm were 91.22%, 89.91%, 68.23%, and 95.23%, respectively.
