Comparative analysis of diagnostic criteria of classical cardiology and cardiometry

Purpose of research . Cardiometry, which has been developing for more than thirty years, has achieved certain results that make it possible to expand the diagnostic capabilities of the ECG. However, the criteria for cardio-metric diagnoses have not yet been included in the regulatory indicators approved by the Ministry of Health. Taking into account the possibilities of cardiometry and the pace of its development, this article provides a comparison of the forecasts obtained by classical and cardiometric methods from the standpoint of interchangeability. The purpose of research is to compare the cardiological diagnoses made on the basis of ECG obtained by classical and cardiometric methods, using the position of interchangeability. Methods . In this paper, the principle of superposition is applied, which consists in using one function to process the results of another. The existing classical result is described using a cardiometric function. As a result, in practice there is a logical possibility of moving to a more accurate diagnosis. At the same time, the basis of the classical diagnosis is not destroyed. Results . A comparative analysis of classical cardiological and cardiometric ECG assessment methods is presented. A total of 11 diagnoses were considered. Specific conclusions and recommendations are made for each comparison. Cardiometry allows a qualitative assessment of: a) The U-wave on the ECG occurs during the early diastole phase. It is associated with the filling of the coronary bloodstream, but the quality of its filling can only be diagnosed using a synchronously recorded rheogram from point T, the end of wave T to the beginning of wave U; b) hyper- and hypocalcemia are evaluated in the S – L phase by the amplitude of the phase; c) hyper- and hypokalemia are evaluated in the L-phase. j by phase amplitude. Conclusion . This work shows the possibilities of expanding the classical cardiological diagnosis based on an ECG.
