Abstract

Obstructive sleep apnea (OSA) is a critical sleep disorder that can lead to severe health complications and even death if left untreated. Early OSA detection through non-invasive methods, such as single-lead electrocardiogram (ECG) analysis, presents a promising approach for timely intervention. In contrast to the existing single-stage convolutional neural network (CNN) and bidirectional long short-term memory-based (BiLSTM) hybrid models, this letter presents DeepApneaNet, a novel end-to-end deep learning framework that combines multiple CNN-BiLSTM-based hybrid subnetworks in a cascaded manner to detect OSA from single-lead ECG signals. With the PhysioNet Apnea-ECG Database, our implemented framework is able to achieve the best per-segment accuracy, sensitivity, and specificity of 88.61%, 84.23%, and 91.04%, respectively. For per recording classification, our model achieved 94.29% accuracy, 100% sensitivity, and 83.33% specificity. Even though using minimal preprocessing and without any hand-crafted feature extraction, the performance of our model is still comparable to the state-of-the-art methodologies. The results indicate that segmenting hybrid models into smaller networks enhances the understanding of sequence dynamics. DeepApneaNet demonstrates significant potential as a practical solution for diagnosing OSA in real-world settings.
DeepApneaNet:用于单导联心电信号睡眠呼吸暂停检测的多级CNN-Bi-LSTM混合模型
阻塞性睡眠呼吸暂停(OSA)是一种严重的睡眠障碍,如果不及时治疗,可能导致严重的健康并发症甚至死亡。通过无创的方法,如单导联心电图(ECG)分析,早期检测OSA是一种有希望的及时干预方法。与现有的单级卷积神经网络(CNN)和基于双向长短期记忆(BiLSTM)的混合模型相比,这封信提出了DeepApneaNet,这是一种新颖的端到端深度学习框架,它以级联的方式结合了多个基于CNN-BiLSTM的混合子网,从单导联心电信号中检测OSA。使用PhysioNet Apnea-ECG数据库,我们实现的框架能够达到最佳的每段准确性、灵敏度和特异性,分别为88.61%、84.23%和91.04%。对于每个记录分类,我们的模型达到了94.29%的准确率,100%的灵敏度和83.33%的特异性。即使使用最少的预处理,没有任何手工特征提取,我们的模型的性能仍然可以与最先进的方法相媲美。结果表明,将混合模型分割成更小的网络可以增强对序列动力学的理解。DeepApneaNet显示了在现实环境中诊断OSA的实际解决方案的巨大潜力。
