The research of heart rhythm variability characteristics spectral estimations quality for different rhythm cardiogram approximations
The comparison of rhythm cardiograms approximation methods as non-equidistant temporary rows by model and real signals heart rhythm variability spectral characteristics estimations stability and effectiveness criteria was carried out. The procedure of rhythm cardiograms specters correction after the use of linear and spline interpolation is developed, the analysis results of its effective application area given.
