A plurality of electrophysiological signals measured by a respective plurality of electrodes carried by a multi-dimensional catheter can be sorted relative to a direction of interest, such as a cardiac activation wavefront direction. An electroanatomical mapping system can be used to determine the orientation of the multi-dimensional catheter relative to the direction of interest. For example, the user can manually adjust the orientation by manipulating a slider, a wheel, or a similar graphical user interface control. As another example, the user can draw a presumed orientation on a geometric model. Once the orientation is determined, the system can sort the plurality of electrophysiological signals and output a graphical representation of the sorted plurality of electrophysiological signals, for example as a plurality of traces.
A method of sorting a plurality of electrophysiological signals measured by a respective plurality of electrodes carried by a multi-dimensional catheter, the method comprising:
A method of determining a sequence in which a cardiac activation wavefront passes through a plurality of electrodes carried by a multi-dimensional catheter, the method comprising:
A system for sorting a plurality of electrophysiological signals measured by a respective plurality of electrodes carried by a multi-dimensional catheter, comprising:
