摘要:

基于云端的深度学习(DL)算法与便携式/可穿戴(P/W)设备相结合,已发展为一种智能医疗系统,可支持利用心电图(ECG)实现心律失常(CAs)自动分类。然而,由于接入消费电子(CE)的P/W设备存在电池和传输带宽限制,长期连续心电监测面临挑战。解决这一挑战的可行方法是降低采样率,但低采样率会导致信号分辨率不足,影响CAs分类性能。本研究提出一种基于DL的心电信号超分辨率框架(名为SRECG),通过结合基于DL的CAs高分辨率多类分类器(HMC)的分类精度,对低分辨率心电信号进行增强。实验中,我们对CPSC2018数据集的心电信号进行降采样,分别评估了使用和不使用SRECG时的HMC精度。结果表明,与传统插值方法相比,SRECG能显著提升HMC精度;此外,经SRECG增强的心电信号可保留HMC约一半的CAs分类精度。该结果证实SRECG可有效增强接入消费电子的P/W设备采集的低分辨率心电信号,提升其云端HMC的性能。

英文摘要:

A combination of cloud-based deep learning (DL) algorithms with portable/wearable (P/W) devices has been developed as a smart heath care system to support automatic cardiac arrhythmias (CAs) classification using electrocardiography (ECG). However, long-term and continuous ECG monitoring is challenging because of limitations of batteries and transmission bandwidth of P/W devices while incorporated with consumer electronics (CE). A feasible approach to address this challenge is to decrease sampling rates. However, low sampling rates lead to low-resolution signals that hinder the CAs classification performance. In this study, we propose a DL-based ECG signal super-resolution framework (called SRECG) to enhance low-resolution ECG signals by jointly considering the accuracies when applied to the DL-based high-resolution multiclass classifier (HMC) of CAs. In our experiments, we downsampled the ECG signals from the CPSC2018 dataset and evaluated their HMC accuracies with and without the SRECG. Experimental results show that SRECG can well improve the HMC accuracies as compared to traditional interpolation methods. Moreover, approximately half of the CAs classification accuracies of HMC were maintained within the enhanced ECG signals by SRECG. The promising results confirm that SRECG can be suitably used to enhance low-resolution ECG signals from P/W devices with CE to improve their cloud-based HMC performances.
