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 e

The paper deals with an analysis of relationship between heart rate described by a sequence of cardiac interbeat intervals and mechanical activity of heart represented by a sequence of systolic forces. Both the quantities were determined from seismoc

The paper deals with an algorithm for identifying parameters of an AR model of the HRV data recorded in horses during stress-test. The developed algorithm estimates positions of poles of the 2nd order AR model representing dominant stationary compone

The paper describes experiments and their results that offered an insight to relationship between RR and QT intervals in equine ECG signals recorded under various conditions. In contrast to human heart in a great number of cases the QT intervals prol

Prolonging of QT intervals was published numerously and it is considered as a significant factor in prediction of sudden death. Available sources are occupied by analysis of static re-cords, i.e. without transient processes. We have recorded ECG data
