Objective: To conduct a comparative analysis of methods for assessing cardiac repolarization over time.
Material and methods: Electrocardiography was performed on 40 patients. At the age of 25-65 years (mean age 52 years). Males prevailed over females (29 people, 72%). Three methods for assessing repolarization were compared: qualitative, semi-quantitative and quantitative. The following methods were selected for the quantitative assessment of electrocardiogram parameters: assessment of the QTc interval duration, T wave amplitude and a new method of contour analysis of the electrocardiogram.
Results: The results of the study indicate that it is possible to record repolarization changes during long-term assessment of the dynamics using both qualitative, semi-quantitative and quantitative methods. However, the degree of expression and nature of the changes presented on the electrocardiogram are better described by contour analysis of the ECG.
Conclusion: The contour analysis method, which takes into account not only the duration of segments and the amplitude of the teeth, but also the change in the shape of ECG elements, better reflects the influence of the acute infectious process on the electrical activity of the heart
Keywords:repolarization; electrocardiography; qualitative assessment; quantitative assessment; contour analysis; new coronavirus infection; SARS- CoV- 2.
