HIGH-RESOLUTION ELECTROCARDIOGRAPHY - RES ULTS OF 4 YEAR STUDIES

Four-years experience with high-resolution electrocardiography in pati ents with different cardiac diseases is summarized in the paper. Sever al computer program packages were used in the assessment of high-resol ution ECGs. Results of analysis of ventricular late potentials, spectr al temporal mapping of the QRS complex, dipole electrocardiotopography (decarto) were compared in patients before and after coronary surgery , in patients with different forms of Ischemic heart disease and in pa tients with and without cardiac arrhythmias. Correlations were found b etween parameters of new methods of evaluation of the process of depol arization (spectral temporal mapping and decarto) and parameters of an alysis of ventricular late potentials. This allows to conclude that hi gh-resolution ECG is able to reveal concealed changes of electrophysio logic properties of the myocardium.
