A digital computer program has been described whih is intended to serve as the basis for automatic interpretation of cardiac arrhythmias. Emphasis has been placed at this time on simulating and quantitatively determining human diagnostic logics with the use of only the temporal location of the P and R waves without regard to their shapes.Primary attention has been given in this paper to separating out and distinguishing between those "dominant" cardiac rhythms which are controlled by the sinus pacemaker (sinus rhythm group). Of 184 test cases belonging to the sinus rhythm group, 174 were correctly identified : 46 of 49 cases of regular sinus rhythm, 113 of 116 cases of sinus arrhythmia, and 15 of 19 cases of marked sinus arrhythmia.<BR>Only 1 of 23 cases belonging to the complicated dominant rhythm group was incorrectly included in the sinus rhythm, eleven of total test cases of 207 were incorrectly diagnosed or could not be assigned a dominant rhythm on the basis of temporal beat distribution alone.<BR>All occasional ectopic beats occurring in the tracing were correctly located in 168 of 184 cases of sinus rhythm group. In 8 cases, some of the occasional abnormalities were overlooked by the program, and in two cases, some parts of an example of marked sinus arrhythmia were mistakenly attributed to the presence of ectopic beats. Three fourth of all the errors encountered in this study were not due to program logic per se but could be attributed to the use of peak-to-peak rather than beginning-to-beginning interval measurements. It is anticipated that the concomitant use of information concerning the shape of the P and R waves would greatly reduce these kinds of errors.
