Abstract: A method and system for mapping an anatomical structure includes sensing activation signals of intrinsic physiological activity with a plurality of mapping electrodes disposed in or near the anatomical structure. The activation signals are used to determine a dominant frequency for each electrode from which a wavefront vector for each electrode is determined based on a difference between the dominant frequency at a first electrode location and the dominant frequency at neighboring electrodes. An anatomical map is generated based on the determined wavefront vectors.

Abstract: An anatomical mapping system includes a plurality of mapping electrodes each having an electrode location and configured to detect activation signals of intrinsic physiological activity within an anatomical structure. A mapping processor is associated with the plurality of mapping electrodes and is configured to record the detected activation signals and associate one of the plurality of mapping electrodes with each recorded activation signal. The mapping processor is further configured to analyze the recorded activation signals to identify at least one recurring pattern based on a relationship between a timing of the detected activation signals and the electrode locations of the mapping electrode associated with each detected activation signal.
