Analysis of the arterial diameter variation wave in radial artery by means of fuzzy logic

A method to analyze a certain number of arterial diameter variation(ADV) waves of normotensive males, obtained in radial artery was developed. The values of the variables that represent the ADV waves were used. The linguistic variables and their linguistic terms in the antecedent and consequent of the inference engine (IE) were defined by means of the triangular and trapezoidal fuzzy numbers. The singleton fuzzy sets in the input premise were used. The fuzzy rules for the inference engines were built and the patients to be tested were selected. Different fuzzy entropies were applied to the inference engines and the biological age that represents the state of the arterial system of the patients was obtained with the minimum fuzzy disorder.
