Arrhythmia analysis with an expert system

We have developed a rule based expert system which was designed to diagnose electrocardiographic arrhythmias in several species. The program, called ECG-X, is written in OPS5 and runs under MS-DOS 2.1 and higher on an IBM-PC or AT type machine. The program uses the paper speed, the species, the temporal relationships between the P waves and the QRS complexes as well as basic information about the P and QRS morphology, and provides the user with a rhythm diagnosis consistent with rules provided by contemporary cardiac electrophysiologic knowledge.
