A method of acquiring and mapping electrophysiological data in a heart chamber includes inserting a catheter into the heart chamber. Electrophysiological data in the heart chamber is acquired with the catheter. The position of the catheter is determined by using an electromagnetic field source external to the heart chamber, and the location of the acquired electrophysiological data is determined using the position of the catheter. Information related to the three-dimensional geometry of at least a portion of the heart chamber is received, and a continuous three-dimensional color-coded map of the electrophysiological data is created and superimposed on a geometrical representation of the three-dimensional geometry information. |
