Influence of α-tocoferol on the cardiac rhythm regulation of nonlinear rats in conditions of acute stress

Introduction of α-tocoferol per os in a dose of 10 mg/kg per body mass periodically during a life of rats modifies reaction of regulatory systems on acute stress as promotes formation of less rigid heart rhythm, but potentiate, especially at the initial stage of stress, sharp rising of power not only LF-, but also VLF-waves of spectrum HRV. The last can testify to intensifying response to stress from up-segmentary level of regulation.
