Abstract

Background: Previous studies have shown that the diagnosis and localization of previous non-Q wave myocardial infarction (NQMI) is possible by body surface potential mapping (BSPM), but the criteria for the discrimination between anteroseptal and inferoseptal middle regions remain to be determined. Methods: BSPM using 63 unipolar leads was recorded in 119 patients with previous NQMI (36 to 76 years of age, average 61 years; 85 men). Localization of anteroseptal or inferior middle NQMI occurred in 70 cases (44 to 76 years of age, average 61 years, 53 men) by determining early anterior minimum potential with only slight negativity. In these cases, isopotential maps obtained at additional time points were investigated to discriminate between anteroseptal and inferoseptal NQMI. The clinical localization was based on the concordance of two of the following tests: wall motion disturbances on echocardiography, coronary angiogram and repolarization changes in the acute-phase electrocardiogram. Results: Two milliseconds before the appearance of the first anterior minimum, a more accentuated superior negativity indicated anteroseptal NQMI (32 of 70 cases), while a more pronounced inferior negativity indicated inferoseptal NQMI (38 of 70 cases). Fisher's exact test showed statistically significant associations between the above BSPM localizations and the clinical localizations (P
