FIELD: medicine.

SUBSTANCE: invention relates to medicine. In method realisation current values of each of parameters of clinical data characterising current state of cardiovascular system are measured and fixed. Results of assessment of values of clinical data parameters are transformed. Results of assessment of current values of each parameter of clinical data are fixed depending on time of performed measurements. Results of transformation of assessment of current values of each parameter of clinical data are visualised on plane, coinciding with plane of displaying multicolour screen of videomonitor. Information about dynamics of cardiovascular system state is obtained. Also performed is digitisation and weighting of fixed instant values of each parameter of clinical data in physical values. Three-dimensional image of cardiovascular system state A_N(t) is created in form of totality of geometrical places of points in N-dimensional space of cardiovascular system states, with coordinates of each point of N-dimensional space of cardiovascular system states being determined by totality of non-invasively and invasively measured in physical values digitised instant values of various clinical data, which characterise current state of cardiovascular system. Two-dimensional images of cardiovascular system states A₂(t) are formed in form of projections of formed A_N(t) on plane, coinciding with plane of displaying multicolour screen of videomonitor. Coordinates in 2-dimensional state of cardiovascular system states of each point of formed A₂(t) are memorised. Virtual three-dimensional models of various nosologic forms of cardiovascular system diseases B_i are built in form of totality of M-geometrical places of points in N-dimensional space of cardiovascular system state, where i=1; 2; 3;…M is the number of displayed diseases of cardiovascular system. Coordinates of each point of each of B are determined by totality of values of various clinical data in physical values, describing characteristic clinical-morphological picture of corresponding disease and degree of CVS pathology manifestation, respectively. Coordinates in N-dimensional space of cardiovascular system state of all points of three-dimensional images B_i are memorised. Two-dimensional models of various nosologic forms of cardiovascular system diseases B_2i are formed in form of projections, formed by B_2i on plane, coinciding with plane of displaying multicolout screen of videomonitor. Coordinates in 2-dimensional space of cardiovascular system state of all points formed by B_2i are memorised. Formed B_2i are visualised on screen of multicolour videomonitor in such a way that colour of each point B_2i in visible ranges of wavelengths Δλ_r, Δλ_o, Δλ_y, Δλ_g, Δλ_b…Δλ,_m corresponds to certain type of disease, and degree of pathology is characterised by value, inversely proportional to wavelength of respective range. Visualisation on screen of multicolour videomonitor of successively formed in time values A₂(t) is also performed, with each previous value A₂(t) being connected by means of straight lines with their following values, and colour of A₂(t) and connecting straight lines is formed by addition of red (Δλ_r), green (Δλ_g) and blue (Δλ_b) colours with similar amplitude proportion. Check of satisfaction of set of conditions A₂(t) ⊂ B_2i is carried out. Decision about cardiovascular system disease is taken in case of satisfaction of a condition from set A₂(t) ⊂ B_2i. Ambiguity of taking decision about cardiovascular system disease is excluded if mutual intersections B_2i are present, when instant value A₂(t) simultaneously belongs to two and more B_2i, by formation on screen of multicolour videomonitor of each of new images of state $$A_2^k\left(t\right)$$ and non-intersecting images of diseases $${в}_{2i}^k$$ by respective k transmissions of origin of coordinates of N-dimensional space of cardiovascular system state into selected by cardiologist points on plane of multicolour screen of videomonitor and carrying out procedure of projecting A(t) and B_i on plane coinciding with plane of displaying multicolour screen of videomonitor and after each of k transmissions of origin of coordinates of N-dimensional space of cardiovascular system state, where k=1; 2; 3;…j. Formed $$A_2^k\left(t\right)$$ and $${в}_{2i}^k$$ are visualised on screen of multicolour videomonitor. procedure of $$A_2^k\left(t\right)$$ and $${в}_{2i}^k$$ formation is stopped when condition, when $$A_2^k\left(t\right)$$ belongs only to one $${в}_{2i}^k$$ is satisfied. Decision about absence of disease is taken if condition A₂(t) ⊄ B_2i is satisfied. Assessment of dynamics of change of cardiovascular system state is performed by results of analysis of preliminarily determined values of quantities Δ_τ=A₂(t₁)-A₂(t₂) and $$\raisebox{1ex}{$d{\Delta }_{\tau }$}\!\left/ \!\raisebox{-1ex}{$d\tau $}\right.$$ for specified time interval, where t₁; t₂ are moments of time of beginning and end of specified time interval respectively.

EFFECT: invention makes it possible to simplify process of operative analysis of clinical data by set of measured clinical signs and avoid mistakes in generation of medical control decision for diagnosing.
