We concentrate on computational implementations of the detection of ischaemic episodes in order to allow continuous monitoring of patients interned in Coronary Care Units (CCU). The consideration of several alternatives led us to choosing an implementation based on the expert's knowledge as the most adequate. In order to solve the problem of transforming the imprecise knowledge provided by the expert into computable structures we have decided to make use of a fuzzy implementation. We illustrate and comment the operation of our solution over some records of the European ST - T Database, which is an electrocardiographic database specifically aimed at the validation of algorithms whose objective is the detection of ischaemic episodes. This work can be included in the more general problem of the design, physical implementation and validation of an electronic-computational system (SUTIL), which by means of the simultaneous, integrated and intelligent evaluation of a large amount of information extracted from real time processing of haemodynamic and electrocardiographic signals, performs an intensive and exhaustive follow up of patients with ischaemic cardiopathies interned in CCUs. © 1996 - Elsevier Science B.V.
