title: Application of fuzzy graph theory to evaluation of human cardiac function.
abstract: To explore the possibility of application of the fuzzy graph theory to the evaluation of human cardiac function, the cardiac function of two groups of personnel working under special environment were evaluated using the method of fuzzy graph theory. The first group consists of 31 subjects aged 19-21 years. They were classified according to their cardiac function evaluated by the method of maximum support tree. While the second group consists of 24 subjects aged 30-40 years and were classified with fuzzy graph theory on the basis of 6 maximum principal components extracted from 16 physiological indices. Medical explanation of the results is convincing.
