Amplitude characteristic of the electric field of the heart

To study the electrical activity of the heart, the method of electrocardiotopography (ECTG) was used according to the method of R. 3. Amirov (1973). Integral topography was used to study the amplitude characteristics of the QRS complex. When constructing integral topograms, a Wilson system of monopolar leads with ECG recording from 84-110 points of the chest surface was chosen. In addition to the visual analysis of the ECG, the amplitudes of the teeth were calculated, the measurement results were transferred to the electropositivity map (EP--), combining the R and K teeth, and to the electronegativity map (EN—), combining the Q and S teeth. After constructing the integral topograms, the nature of the relief of the electric field of the heart, projections of potential maxima, their magnitude and localization, overlap zones, the presence of zero zones, discontinuities of the circular motion of the dipole were determined.
