1. A method of delivering ablation therapy in a heart chamber, comprising:

  • a) inserting a catheter in the heart chamber;

    b) acquiring electrophysiological data in the heart chamber with the catheter;

    c) determining the position of the catheter by using an electromagnetic field source external to the heart chamber;

    d) determining the location of the acquired electrophysiological data in step (b) using the position determined in step (c);

    e) integrating the information of steps (b) and (d);

    f) receiving information related to the three-dimensional geometry of at least a portion of the heart chamber from the position determined in step (c);

    g) creating a continuous three-dimensional, color-coded map of the electrophysiological data superimposed on a geometrical representation of the three-dimensional geometry information received in step (f); and

    h) utilizing the map to deliver ablation therapy.
