Abstract

The recent development of body surface Laplacian mapping has shown increased capability for resolving multiple epimyocardial electrical events. For the myocardial infarction (MI) patient, accurate localization of the site and extent of infarct remains a critical issue, and the body surface Laplacian map (BSLM) may serve as a useful tool for this purpose. One hundred and ® fty lead electrocardiogram (ECG) recordings were taken over the anterolateral chest of ® ve anterior MI patients. After 20-beat averaging of the potential ECGs, the Laplacian ECGs were calculated using a ® nite di. erence estimation algorithm. BSLMs of the anterior MI patients showed a highly localized early negativity overlying the site of infarct, which was determined by echocardiography. Compared to the corresponding body surface potential maps, the BSLMs showed a more localized area of activity corresponding to the anterior infarct site, as judged by echocardiographic interpretation.
