Cardio Signals Extraction Based on Finite Sums of Exponential Functions
The aim of the work was to adapt the analysis of the ranks and mapping the specific region of QQ intervals based on employment of finite sums of exponential functions to three synchronously recorded cardio signals – electrocardiogram (ECG), impedance cardiogram (ICG) and seismocardiogram (SCG). Reconstruction algorithm that incorporates the standard value and quality measure is presented in this work. The results show that expression of cardio signals by Hankel matrix and mapping of the specific region based on employment of sum of exponential functions could be useful for development the diagnostic technologies in future.
