1. A system comprising:

  • a plurality of sensors configured to measure electrophysiological signals from cardiac tissue associated with a patient;

    an ablation catheter configured to deliver an ablative therapy by applying one or more of heating, cooling and high-frequency; and

    a computing device coupled to the plurality of sensors, the computing device comprising;

    memory storing machine readable instructions and configured to store electroanatomic data; and

    at least one processor configured to access the memory and execute the machine readable instructions,wherein the machine readable instructions are further configured to perform, when executed, a method comprising;

    measuring the electrophysiological signals;

    storing the electroanatomic data that corresponds to the electrophysiological signals measured by the plurality of sensors;

    computing phase data for each of a plurality of points of a geometric surface corresponding to the cardiac tissue based on the electroanatomic data for at least one-time interval;

    encoding the phase data to a first color component representing a dimension of a multi-dimensional color model, wherein the multi-dimensional real time model comprises at least two dimensions;

    computing magnitude data for each of the plurality of points of the geometric surface corresponding to the cardiac tissue based on the electroanatomic data for at least one-time interval;

    encoding the magnitude data to a second color component representing another dimension of the multi-dimensional color model; and

    generating the output data corresponding to a multi-parameter graphical map for the geometric surface corresponding to the cardiac tissue of the patient by mapping the phase data to the first color component and the magnitude data to the second color component;

    displaying the multi-parameter graphical map for the geometric surface corresponding to the cardiac tissue of the patient;

    configuring one or more control parameters for delivering the ablative therapy to the cardiac tissue based on the multi-parameter graphical map;

    delivering the ablative therapy to the cardiac tissue according to the one or more control parameters; and

    reconfiguring the one or more control parameters intraoperatively during delivery of the ablative therapy based on one or more changes to the output data reflected in the multi-parameter graphical map.
