The precordial electrocardiographic map may be useful for non-invasive assessment of the extent of the acutely infarcted myocardium. Rapid and serial precordial electrocardiographic maps also may be useful to evaluate the effects of intervensions of drugs and efforts on the ischemic myocardium. In this study, the IBM-Bonner program was applied to produce a system for the precordial electrocardiographic map. Six electrodes at one intercostal space were moved in parallel from the second to the seventh intercostal space. Thus electrocardiograms (ECGs) could be recorded from 36 precordial sites, 6 x 6 matrix, and analyzed using the IBM-Bonner program. The measured values of the ECG waveform make feasible the automatic procurement of the precordial electrocardiographic map. Our mapping program can be used readily and anywhere the IBM-Bonner program is in use.
