An automatic diagnosis program for electrocardiogram is developed by the use of artificial intelligence approach. The program consists of two parts, the measuring part and the reasoning part. The measuring part is to extract some typical features associated with the electrocardiogram recorded over the chest. The reasoning part is a production system constructed using Prolog. The automatic diagnosis is realized through the human-like reasoning process based on the production system instead of a simple judgement system for the measured numerical data. The production system is capable of replacing or adding the diagnostic knowledge and data with a very simple manner. To cope with the vagueness of the knowledge, fussy sets with proper membership functions are introduced for the matching certainty in the course of the production. The reliable degree of the diagnosed results finally obtained is expressed in terms of the certainty factor which is given as the sum of the weighted value of the matching certainty assigned to each symptom. Some diagnosed results are demonstrated and discussed in comparison with the results obtained by means of a popular so-called intelligent electrocardiograph.
