Body-surface electrocardiographic (ECG) Laplacian mapping has been shown to be an economical and effective noninvasive technique to image the spatially distributed cardiac electric activity. Experimental studies demonstrate the feasibility of performing body-surface Laplacian ECG mapping using digital signal processing techniques. Body-surface Laplacian mapping has also been used to assist in the diagnosis of cardiac conduction abnormalities. Further experimental and clinical studies are needed to reveal the diagnostic power of this technique in imaging cardiac electrical activity.
