Systems and methods for orientation independent sensing

A system for analyzing signal quality of a plurality of electrodes in contact with a surface of a heart, the system comprising:

• an electronic control unit configured to:
• acquire electrophysiology signals from a plurality of electrodes;
• select at least one clique of electrodes from the plurality of electrodes;
• process the electrophysiology signals from the at least one clique to derive a plurality of local E field data points associated with the at least one clique of electrodes;
• and
• analyze the E field data points associated with the at least one clique of electrodes to determine whether a quality of the electrophysiology signals is affected.
