论文摘要
对于诊断目的，多通道心电图测量值的连续和长期获取非常重要。在文献中提出了压缩感应，用于获得连续的心电图测量值，因为它提供了优势，包括减少测量数量，功耗减少和传输带宽。然后，进行压缩ECG测量的重建以分析用于诊断目的的测量值。但是，重建心电图测量在计算上是昂贵的。因此，在本文中，ECG分析是在压缩域中进行的，而无需诉诸重建。 MIT-BIH心律失常数据库的多通道ECG测量用于验证压缩域ECG分析。使用确定性传感矩阵以形态保存形态，以各种压缩比（CR）压缩ECG信号。结构相似性度量用于定量证明压缩测量的保真度。通过压缩的ECG测量在压缩域中检测到R峰。检测性能指标，例如敏感性，积极预测性和检测率随着CR的增加而降低。
Continuous and long term acquisition of multi-channel ECG measurements are significant for diagnostic purposes. Compressive sensing has been proposed in the literature for obtaining continuous ECG measurements as it provides advantages including a reduced number of measurements, reduced power consumption and bandwidth for transmission. Reconstruction of the compressed ECG measurements is then done to analyze the measurements for diagnostic purposes. However, reconstruction of ECG measurements is computationally expensive. Therefore, in this paper, ECG analysis is carried out in the compressed domain without resorting to reconstruction. Multi-channel ECG measurements from MIT-BIH Arrhythmia database is used to validate the compressed domain ECG analysis. ECG signals are compressed at various compression ratios (CR) using morphology preserving deterministic sensing matrix. Structural similarity measures are used to quantitatively demonstrate the fidelity of the compressed measurements. R-peaks are detected in the compressed domain from compressed ECG measurements. Detection performance metrics such as sensitivity, positive predictivity and detection rate decrease as CR increases.
