METHOD FOR DIAGNOSING CARDIAC SYSTEM FUNCTIONAL STATE Russian patent published in 1999 - IPC

FIELD: medicine. SUBSTANCE: method involves measuring breathing frequency, breathing volume, oxygen consumption, pulse, vital lung capacity, breathing pulse, oxygen pulse in several groups of patients (healthy people, aortic stenosis patients, second and third degree mitral stenosis patients, and others) for all kinds of diseases to be diagnosed. Matrices are built from data received. The matrices are processed by applying factor analysis methods. Loading weights are determined from healthy people group data to evaluate each parameter significance. Factor diagrams are built for every disease group to describe each disease and its severity degree. The factor diagrams are used later as references when compared to those of a patient to be diagnosed. A disease is diagnosed when patient factor diagram coincides with one built for groups of patients possessing known disease types. EFFECT: accelerated detection of type and degree of pathologic changes in treating cardiac diseases. 4 cl, 6 dwg, 4 tbl
