[Effect of acute normobaric hypoxia on electrical stability of the myocardium in healthy people]. 2001

A M Shutov, and Iu V Midlenko, and M V Menzorov, and O A Vrazhnov, and L S Kulikova

We studied the impact of acute 10-min normobaric hypoxia on myocardial electrical stability, systolic and diastolic cardiac 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. Electrocardiographic investigation with assessment of QT-interval must be mandatory before normobaric hypoxic therapy is started. Prolonged QT interval is contraindication to normobaric hypoxic therapy.
