Suppression of global activation signals during anatomical mapping
Abstract:
A method for mapping an anatomical structure includes sensing activation signals of intrinsic physiological activity with a plurality of electrodes disposed in or near the anatomical structure, identifying at least one of the electrodes not in direct contact with the anatomical structure, and adjusting the activation signals sensed by each of the plurality of electrodes based on the activation signals sensed by the identified at least one of the electrodes not in direct contact with the anatomical structure.
