Key result
120-lead body surface potential mapping achieved classification rates of 82% for anterior MI, 93% for posterior MI, and 100% for inferior MI at a specificity of 95%.
Why the study?
Does 120-lead body surface potential mapping improve the detection of ST segment changes in acute myocardial infarction compared to normal controls?
Case-Control (n=290)
Does 120-lead body surface potential mapping improve the detection of ST segment changes in acute myocardial infarction compared to normal controls?
Body surface potential mapping reveals that the most significant ST segment changes in acute MI often occur outside standard precordial lead positions, suggesting that alternative lead selection could improve diagnostic sensitivity for reperfusion therapy.

May support expanded-lead ECG for MI detection; leaves open prospective outcome validation before clinical adoption.
Kornreich et al. (1993) conducted a case-control in Acute myocardial infarction (n=290). 120-lead body surface potential mapping (BSPM) vs. Normal control subjects was evaluated on Classification rates for myocardial infarction (anterior, inferior, posterior) versus normal controls. 120-lead body surface potential mapping achieved classification rates of 82% for anterior MI, 93% for posterior MI, and 100% for inferior MI at a specificity of 95%.
