The aim of this study is to examine the impact of acute 10-min normobaric hypoxia on myocardial electrical stability, systolic and diastolic left ventricular functions in 10 young healthy men. Hypoxia induced a decrease of ejection fraction and left ventricular early peak filling velocity. The QTc interval was prolonged during normobaric hypoxia without QT dispersion increase. The assessment of QT-interval must be mandatory before normobaric hypoxic therapy is started.
