Abstract :
A causal probabilistic model is described which unifies the related arrhythmological and cardiopathological concepts in a homogeneous diagnostic network and gives a mechanism to estimate the risk when competitive sport activity is exercised. The records from 766 amateur and top-level athletes from 1974 to 1991 provided the medical expertise for the weighting of the nodes in the network. Some cognitive issues of Pearl´s belief propagation for singly connected graphs explain the design. The model holds 60 finding nodes and 50 internal concepts. For a number of chosen athletes, the fitness estimation is compared with the clinical decision
