1. A system comprising:
- one or more electrodes configured to measure physiological signals in response to electrical activity in a heart cavity having a surface;
a processing unit configured to determine, based at least in part on Laplace'"'"'s equation, bipolar physiological information at multiple locations of the surface based on physiological signals measured by the one or more electrodes and positions of the electrodes with respect to the surface; and
a display that displays an electro-anatomical map (“
EAM”
), the EAM comprising an electro-anatomical depiction of at least a portion of the surface of the heart cavity, the EAM further comprising the determined bipolar physiological information.

Abstract
In some aspects, a method includes measuring unipolar signals at one or more electrodes in response to electrical activity in a heart cavity. The method also includes determining, based at least in part on Laplace'"'"'s equation, bipolar physiological information at multiple locations of a surface based on the measured unipolar signals and positions of the one or more electrodes with respect to the surface.
