An expert ECG acquisition and analysis system

Abstract

The design aspects and actual implementation phase of an expert system as an aid for the analysis and diagnostics of cardiac infirmities is presented. An IBM-PC compatible microcomputer containing the necessary interface cards for the acquisition of ECG (electrocardiograph) signals is used. The system provides electronic switching of the ECG lead configurations. A data and control flow diagram is used for the analysis of the software of the proposed system. Particular attention is given to signal acquisition, signal processing data, data management, the knowledge base inference engine, and the man-machine interface.<>
