Creating Multiple Layers Of Electro-Anatomical Mappings of Cardiac Tissue at Different Depths Using Multi-Polar Signals

A system comprising:

• one or more processors in communication with a plurality of electrodes of a multi-electrode catheter;
• a display;
• and
• a memory in communication with the display and the one or more processors;
• wherein the one or more processors are collectively configured to perform the following for a plurality of locations of cardiac tissue in a heart:
• receive electrical activity from a multi-electrode catheter within a heart of a patient, wherein the multi-electrode catheter has a first plurality of electrodes on a first side and a second plurality of electrodes on a second side;
• wherein at least one of the first plurality of electrodes on the first side is proximate to cardiac tissue at a first location and at least one of the second plurality of electrodes on the second side is facing away from the cardiac tissue in the heart;
• and wherein the electrical activity is received from at least one electrode on the first side and the at least one electrode on the second side;
• perform a signal analysis of electrical activity at the first location of cardiac tissue based on first signals received from the at least one electrode on the first side and second signals received from the at least one electrode on the second side, wherein the signal analysis is based at least in part on distances between electrodes on different sides of the multi-electrode catheter;
• and
• generating, based on the signal analysis, at least one electro-anatomical map of the heart depicting electrical activity or scar tissue at the first location and the plurality of further locations of cardiac tissue.

A computer-readable storage medium comprising program code for causing a computer to perform the following for a plurality of locations of cardiac tissue in a heart:

• receive electrical activity from a multi-electrode catheter within the heart of a patient, wherein the multi-electrode catheter has a first plurality of electrodes on a first side and a second plurality of electrodes on a second side;
• wherein at least one of the first plurality of electrodes on the first side is proximate to cardiac tissue at a first location and at least one of the second plurality of electrodes on the second side is facing away from the cardiac tissue in the heart;
• and wherein the electrical activity is received from at least one electrode on the first side and the at least one electrode on the second side;
• perform a signal analysis of electrical activity at the first location of cardiac tissue based on first signals received from the at least one electrode on the first side and second signals received from the at least one electrode on the second side, wherein the signal analysis is based at least in part on distances between electrodes on different sides of the multi-electrode catheter;
• and
• generating, based on the signal analysis, at least one electro-anatomical map of the heart depicting electrical activity or scar tissue at the first location and the plurality of further locations of cardiac tissue.
