A complete system with capabilities to provide automatic clinical evaluations of standard 12-lead electrocardiograms has been developed. The basic equipment includes a magnetic tape ECG machine and a mediumsized digital computer. The computer accepts data directly by telephone or by tape playback. Each of the 12 leads is converted to digital samples, measured, and stored. A three-step program then recalls the measurements to be condensed, combined, and refined to one or several diagnostic statements. These are immediately available for use at the processing center or may be transmitted by teletype to the clinical site.
