This paper deals with development of a method for the data analysis of medical expert system by pulse diagnosis. One of the main directions of an application for artificial intelligence in medical practice is attempts to build a new clinical decision-making support system at the expert-level. Medical diagnosis is based on the pathophysiological process, which is a not very common in compared to other approaches, as described by several disease symptoms. As a result, scientists were developed different methods for the medical data analysis. Among these methods, mathematical methods for medical data analysis have been actively developed with compare to other working methods.
