CPC A61B 5/367 (2021.01) [A61B 5/287 (2021.01); A61B 5/339 (2021.01)] | 15 Claims |
1. A method of mapping local conductive activity in a lesion comprising:
receiving a plurality of electrophysiology (EP) data points at an electroanatomical mapping system including a high-density grid catheter and a display, wherein each EP data point of the plurality of EP data points includes electrophysiological signals measured by the high-density grid catheter;
computing, with the electroanatomical mapping system, a metric for each EP data point using the electrophysiological signals for the respective EP data point;
using the electroanatomical mapping system to define an optimized omnipole orientation for the respective EP data point using the electrophysiological signals for the respective EP data point by:
computing a plurality of omnipolar electrograms for the respective EP data point using the electrophysiological signals for the respective EP data point;
computing a plurality of scalograms corresponding to the plurality of omnipolar electrograms;
computing a plurality of peak-frequency functions corresponding to the plurality of scalograms; and
defining an orientation exhibiting a maximum peak frequency of the plurality of peak-frequency functions as the optimized omnipole orientation for the respective EP data point; and
outputting on the display a graphical representation that facilitates visualization of one or more conduction gaps in the lesion using the metrics.
