Special Issue Information

Dear Colleagues,

Compressed sensing (CS) has recently been applied to ECG monitoring systems with the aim of either compressing the acquired data rate, reducing the noise, or even processing the ECG signal to discover anomalies.

This Special Issue seeks innovative contributions on the application of recent CS results to the acquisition and processing of ECG signals, related but not restricted to the following topics:

  • Signal acquisition schemes based on CS;
  • Signal dictionaries and methods for dictionary optimization, learning, and adaptation;
  • Reconstruction algorithms;
  • Characterization and assessment of CS ECG monitoring systems;
  • Hardware implementations of ECG monitoring systems based on CS;
  • Analog-to-information converters for ECG monitoring;
  • Processing of ECG samples acquired by CS;
  • CS-based ECG signal denoising;
  • Anomaly detection from compressed samples;
  • CS-based heartrate and heartrate variation measurements;
  • CS-based Internet of Things and Internet of Medical Things systems;
  • Machine learning for CS;
  • Energy-efficient CS systems;
  • CS-based ECG segmentation and feature extraction.

This paper presents an innovative method for multiple lead electrocardiogram (ECG) monitoring based on Compressed Sensing (CS). The proposed method extends to multiple leads signals, a dynamic Compressed Sensing method, that were previously developed on a single lead. The dynamic sensing method makes use of a sensing matrix in which its elements are dynamically obtained from the signal to be compressed. In this method, for the application to multiple leads, it is proposed to use a single sensing matrix for which its elements are obtained from a combination of multiple leads. The proposed method is evaluated on a wide set of signals and acquired on healthy subjects and on subjects affected by different pathologies, such as myocardial infarction, cardiomyopathy, and bundle branch block. The experimental results demonstrated that the proposed method can be adopted for a Compression Ratio (CR) up to 10, without compromising signal quality. In particular, for CR= 10, it exhibits a percentage of root-mean-squared difference average among a wide set of ECG signals lower than 3%. Full article

This paper presents a new approach for the optimization of a dictionary used in ECG signal compression and reconstruction systems, based on Compressed Sensing (CS). Alternatively to fully data driven methods, which learn the dictionary from the training data, the proposed approach uses an over complete wavelet dictionary, which is then reduced by means of a training phase. Moreover, the alignment of the frames according to the position of the R-peak is proposed, such that the dictionary optimization can exploit the different scaling features of the ECG waves. Therefore, at first, a training phase is performed in order to optimize the overcomplete dictionary matrix by reducing its number of columns. Then, the optimized matrix is used in combination with a dynamic sensing matrix to compress and reconstruct the ECG waveform. In this paper, the mathematical formulation of the patient-specific optimization is presented and three optimization algorithms have been evaluated. For each of them, an experimental tuning of the convergence parameter is carried out, in order to ensure that the algorithm can work in its most suitable conditions. The performance of each considered algorithm is evaluated by assessing the Percentage of Root-mean-squared Difference (PRD) and compared with the state of the art techniques. The obtained experimental results demonstrate that: (i) the utilization of an optimized dictionary matrix allows a better performance to be reached in the reconstruction quality of the ECG signals when compared with other methods, (ii) the regularization parameters of the optimization algorithms should be properly tuned to achieve the best reconstruction results, and (iii) the Multiple Orthogonal Matching Pursuit (M-OMP) algorithm is the better suited algorithm among those examined.
