[Preclinical ECG changes and their evaluation based on the criterion of symmetrical approach].
To reveal preclinical cardiac performance changes, conventional and unique ECG processing procedures were used in 101 individuals. A classification of heart function was developed, which was based on a comprehensive assessment of ECG. The results of the clinicofunctional classification were well comparable with those of a quantitative ECG analysis made with heuristical methods. The ratios of various ECG parameters are more informative than the absolute values of these parameters. In screening, the quantitative ECG analysis have some advantages over the visual one as it requires no thorough clinicopharmacological study. The symmetrical approach to an ECG analysis with the use of geometrical methods of simulation may be useful for the criterion assessment of preclinical alteration in cardiac performance.
