Effect of fiber orientation on propagation: electrical mapping of genetically altered mouse hearts.

Abstract excerpt

BACKGROUND: Epicardial potentials reveal the strong effects of fiber anisotropy, rotation, imbrication, and coupling on propagation in the intact heart. From the patterns of the surface potentials, we can obtain information about the local fiber orientation, anisotropy, the transmural fiber rotation, and which direction the wave front is traveling through the wall. In this study, lessons learned from epicardial...
