HES EKG expert-an expert system for comprehensive ECG analysis and teaching

An expert system for comprehensive electrocardiographic diagnosis has been developed. The system provides ECG (electrocardiogram) processing by the HES ECG program, a database with validated ECGs and their accompanying clinical findings, and a knowledge base containing established rule sets for ECG classification (Cardiac Infarction Injury Score, Romhilt Estes Hypertrophy score, the Selvester score system, etc.). For access to the database a group definition language has been developed; and a rule definition language is provided for creation of rule sets and diagnostic classification algorithms. Rule sets may be applied to single cases or groups of cases (batch processing). Reasoning is provided by using the backward chaining inference engine, which generates a structured reasoning path.<
