Abstract
Shortening of RR intervals is often associated with prolonging QT intervals in dynamic studies of the cardiovascular activity in horses. Causes of the relationship have not been explained neither in veterinary nor human medicine yet. Our simulation experiments explain that the heart ventricle activity is controlled by at least two phenomena. One of them is stimulating and the other inhibiting. The identified values of the model parameters denote that the control effects are supposed to be both nervous and humoral.
