title: [The contractile function and electrical stability of the heart in different regimens of physical exercise].
abstract: Adaptation to moderate duration of physical loading causes identical levels of increase in threshold fibrillation of ventricles in wide range of their intensity. Rise of contractile heart function increases with prolonged adaptation regimen of heavy loading exercise. With hypokinesia and excessive physical load the sinking of threshold of fibrillation of ventricles occurs in lacking of alterations and with high contractile function of the heart respectively.
