Pulse diagnosis is one of the most distinctive diagnostic methods in traditional Chinese medicine, belongs to the "looking and smelling about" diagnostic method of four diagnostic methods in traditional Chinese medicine, and is a very important ring in traditional Chinese medicine diagnosis. The pulse diagnosis is the pulse condition, i.e. the form of pulse should be pointed. The pulse condition can reflect the comprehensive information of viscera functions, qi and blood, yin and yang, which results from the movement of qi and blood in vessels of the human body. While qi and blood are closely related to viscera functions of the organism, and the viscera functions are changed, so that qi and blood operation is affected, and qi and blood operation fluctuation leads to pulse condition difference. By analyzing the pulse condition variation information, the viscera where the disease occurs and the nature of the disease and the further development of the disease condition can be judged.
