A system and method are provided for determining electrophysiological data. The system comprises an electronic control unit that is 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, determine catheter orientation independent information of a target tissue, and output the orientation independent information to a display. The method comprising receiving electrogram data for a set of electrodes (80), compensating for artifacts in sensor positions in the mapping system (81), resolving the bipolar signals into a 3D vector electrogram in the mapping system coordinates (82), manipulating observed unipolar voltage signals and the tangent component of the e-field to estimate the conduction velocity vector (83), and outputting the catheter orientation independent information (84).
