[Current concepts concerning the syndrome of early ventricular repolarization].

Electrocardiograms of 1000 patients examined in a polyclinic for various diseases and during prophylactic checkups, were analyzed. The syndrome of early ventricular repolarization (SEVR) was detected in 54 (5.4%) patients. According to the proposed classification scheme of SEVR one could determine its clinical value and the distribution of frequency of its variants and types. The authors put forward present-day ideas as to SEVR assumed genesis with an attempt to verify some of them. Differential-diagnostic pharmacological tests (procainamide, quinidine and propranolol) were recommended for SEVR recognition.
