Abstract
The authors have investigated the sensitivity of body surface Laplacian imaging (BSLI) to localize and image myocardial ischemias in a closed chest pig model. The present study suggests that BSLI provides high spatial resolution in noninvasively localizing acute myocardial ischemia, and that the precordial Laplacian ECG provides higher sensitivity in sensing ischemic activity as compared with the unipolar ECG
