Abstract:
This paper investigates the computerized analysis of electrocardiographic signals.
The biological variability, the laáck of standards in the definition of measurements
and of diagnostic criteria make the classification problem a complex task. Two basic
methods of the diagnostic process are described: the statistical model and the deterministic
approach. In particular, a model for ECG classification will be illustrated where
the imprecise knowledge of the state of cardiac system and the vague definition of
the pathological classes are taken care of by means of the fuzzy set formalism.
