To evaluate nonlinear dynamic parameters, the "System Analysis of Heart Rate Dynamics" (SADR) program, utilizing chaos analysis and the short-time Fourier transform (STFT), has proven effective. This program can retrieve data from various file formats, transforming ECG into RR intervals while eliminating artifacts.
