[Systemic design of a new complex of diagnostic cardiological equipment].

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.

[Automated evaluation of the central hemodynamic status using the RKA 3-01 Radiocardioanalyzer].

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.

[Circulating blood volume meter].

The article describes the functional diagram, calibration principle and operation of a new instrument, ur1-7. This device measures the volume of blood circulating in the organism by the radioisotope dilution method. The measurement range is from 1 to 9.
