Real-time feedback for electrode contact during mapping

A method for mapping an anatomical structure, the method comprising:

• sensing signals associated with an anatomical structure with a plurality of mapping electrodes;
• characterizing the signals sensed by the plurality of mapping electrodes based on the amplitudes of the plurality of mapping electrodes;
• determining a quality of contact of the plurality of mapping electrodes with the anatomical structure based on the signal characterization;
• and
• displaying a graphical display representative of the quality of contact of the plurality of electrodes.

A method for mapping an anatomical structure, the method comprising:

• positioning a plurality of mapping electrodes proximate to an anatomical structure;
• sensing signals with the plurality of mapping electrodes;
• characterizing the signals sensed by the plurality of mapping electrodes based on the amplitudes of the plurality of mapping electrodes;
• determining a quality of contact of the plurality of mapping electrodes with the anatomical structure based on the signal characterization;
• displaying a graphical display representative of the quality of contact of the plurality of electrodes;
• repositioning the plurality of mapping electrodes with respect to the anatomical structure;
• and
• updating the graphical display in real-time as the quality of contact of the plurality of electrodes changes when the plurality of electrodes are repositioned.
