Utilization of electrode spatial arrangements for characterizing cardiac conduction conditions

A system for determining electrophysiological data, comprising:

• an electronic control unit configured to:
• receive electrical signals from a set of electrodes;
• receive position and orientation data for the set of electrodes from a mapping system;
• compensate for position and orientation artifacts of the set of electrodes;
• compose cliques of a subset of neighboring electrodes in the set of electrodes, wherein each of the cliques comprise at least three electrodes, wherein the electrical signals comprise a plurality of bipole signals taken between the at least three neighboring electrodes in each of the cliques;
• derive an E-field for a tissue adjacent to each of the cliques from the plurality of bipole signals, wherein bipole signals taken between the at least three neighboring electrodes in each of the cliques overdetermine the E-field for the tissue adjacent that clique;
• determine catheter orientation independent information of a target tissue based on the electrogram data and position and orientation information from the set of electrodes, wherein the catheter orientation independent information comprises a local tangent E-field and an orthogonal unit vector in the direction along which a wavefront is propagating (a);
• and
• output the orientation independent information to a display.
