ABSTRACT
The authors give a brief description of 6 new diagnostic cardiologic devices designed in the USSR. A concept of systemic design of a perspective complex of diagnostic equipment is under discussion. Type of organization of automated working places for a specialist in noninvasive diagnostics and a cardiologist using personal computers is proposed. Such an approach to the design and use of new diagnostic equipment has been shown promising.

The authors presented the results of a clinical use of a new radiocardioanalyzer RKA 3-01 (manufactured in the USSR) providing for automated measurements and computations of indices of the central hemodynamics during studies using a method of dilution of radioactive nuclides. The main technical potentialities of the device designed on the basis of microprocessor technology, were described. The authors also provided the results of automated computation of the circulating blood volume and the main hemodynamic indices in a group of patients. Values of the hemodynamic indices were shown to correspond to actual ones and comparable to control ones and clinical evidence. The comparison of automated processing with a manual method of calculation indicated a significant coincidence of index values. The clinical use of the radiocardioanalyzer RKA 3-01 for automated assessment of the indices of the cardiovascular system was shown to hold promise among various groups of patients.
