[Mathematical simulation model of cardiac contraction]

The authors describe a mathematical model simulating cardiac contraction based onMaxwell's well known analogue model. The general equations of the model are presented and discussed in relation to published findings. The functioning and compute application of the model are briefly described. The investigations were carried out in normal subjects and in some cases with simulated pathology. The first results obtained with the model and their relation to some biological phenomena (hemodynamics, ATP phasic activity, cardiac contractility) are discussed. The hypotheses on which the model is based are also discussed.
