Abstract—The suggested approach for searching informative features of a pulse signal is based on sequential
analysis of the characteristics of the waveform and the shape of rhythmic structure of the signal. At the first
stage of the analysis, the pulse waveform is determined. The results allow the algorithm of the analysis of the
rhythmic structure to be selected depending on the type of the pulse waveform. The difference of the analysis
algorithms is caused by the fact that the type of the waveform determines the number of local parameters that
affect the rhythmic structure. The suggested algorithm allows its parameters to be corrected at each stage of
the analysis depending on the results of the previous stage. This gives the opportunity to take specific features
of the pulse signal into account and, hence, improves the quality of recognition of diseases by the pulse analysis.
