Abstract
Aim: To examine a reaction of young physically active men with early repolarization phenomena (ERP) on an inhalation of a hypoxic gas mixture (IHGM).
Material and Methods.17 men (6 with ERP & 11 without it) participated in our study. ECG, echocardiography, clinical blood test and erythropoietin blood test were carried out to every of them initially and on the 1-st and 10-th days after the IHGM.
Results. It was found that end systolic volume was 13,8% more (р = 0,01) and ejection fraction was 8% less (р = 0,01) in ERP group than in non ERP group. These indicators were not change after IHGM. In ERP group on 1-st day after IHGM erythropoietin concentration was 79% more (р = 0,027) and on a 10-th day was 64% more (р = 0,003) than in non-ERP group. In ERP group high fluorescent reticulocyte count on a 1-st day after IHGM was 69% more (р = 0,03) and middle fluorescent reticulocyte count on a 10-th day after IHGM was 13% more (р = 0,04) than in non-ERP group. On a 10-th day after IHGM hematocrit and hemoglobin concentration were 5% (р = 0,01) and 12% (р = 0,01) less than in non ERP group.
Conclusion. Thus, men with ERP have a pronounced reaction of the erythropoiesis system on normobaric hypoxia.
