A program for processing of multiple-lead exercise ECGs in real time.

A computer program for continuous recording and real-time processing of 8-channel exercise ECGs is presented. Current average ECG complexes and trends of various morphological and rhythmic parameters can be displayed on a TV monitor during the stress test. Average complexes computed every 10 s, the time of occurrence and 6 morphological coefficients of all detected tentative QRS complexes, and data manually entered by the operator are stored in a file on disk. The operational procedures and the principal signal processing are briefly presented. The main attention is given to a description of the software structure, explaining the subdivision of the program into dedicated autonomous sections and the system for the coordination of simultaneous activities of different priority.
