Abstract

Before accurate, non-invasive, electrical images of the heart can be reconstructed several issues must be addressed. Geometric models must be created to match the subject, the appropriate resolution of the computational mesh must be determined and a continuous potential field must be generated from discretely sampled ECG signals. We investigate each of these issues with reference to a porcine model
