Imaging and visualization of 3-D cardiac electric activity.

Noninvasive imaging of cardiac electric activity is of importance for better understanding of the underlying mechanisms and for aiding clinical diagnosis and intervention of cardiac abnormalities. We propose to image the 3D cardiac bioelectric source distribution from body-surface electrocardiograms...
