Based on an analysis of 4980 ECGs of patients, the authors could distinguish and classify the clinico-electrocardiographic versions of the early ventricular repolarization syndrome (EVRS): permanent, occurring for the first time, suddenly disappearing, intermittent with a gigantic T wave; with a negative T wave, with a short-term T wave inversion, marked by the combination with Wolff-Parkinson-White syndrome, and additional chordae of the left ventricle. The clinico-electrocardiographic classification of the EVRS is of paramount importance for practitioners owing to an assumption that the EVRS is not only a version of the normal ECG but also can be a marker of CHD. The authors view the EVRS as an independent version of the preexcitation syndrome along with Wolff-Parkinson-White and CLK syndromes, with the manifestations of which it may combine.

The prevalence of the early ventricular repolarization syndrome (EVRS) was examined in 129 patients with congenital and acquired heart diseases. Dynamic ECG values were assessed. The most prevalence rate was found in patients with congenital heart disease (100%), aortic (80%), mitral (51%), and aorto-mitral valvular (60%) diseases. The prevalence of EVRS, the mechanisms of its occurrence were associated with the performance of accessory pathways and the manifestation of the competitive nature of the functional interaction between the basic and accessory pathways.
