Abstract
A method consisting of formulating a one-to-one correspondence between locations on a three-dimensional surface of a body cavity and coordinates in a two-dimensional coordinate frame representative of the locations. The method also includes recording respective time-varying electrical potentials at the locations. The method further includes displaying a map of the two-dimensional coordinate frame, and presenting respective graphic representations of the time-varying electrical potentials at positions in the map corresponding to the coordinates of the locations.
