    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: A method for mapping an anatomical structure includes sensing activation signals of physiological activity with a plurality of electrodes disposed in or near the anatomical structure, each activation signal having an associated cycle length, estimating an action potential duration and diastolic interval for each cycle length, generating a restitution curve based on the estimated action potential duration and diastolic interval from a preceding cycle length, iteratively optimizing each estimated action potential duration and corresponding diastolic interval to maximize a functional relationship between the estimated action potential duration and estimated diastolic interval from preceding cycle length, and generating an action potential duration restitution curve based on the optimized action potential durations and diastolic intervals.

    Abstract: A system and method for mapping an anatomical structure includes sensing activation signals of intrinsic physiological activity with a plurality of electrodes disposed in or near the anatomical structure. A most recent intrinsic event at a selected time is determined based on the sensed activation signals and a persistent display of relevant characteristics is generated based on the sensed activation signals of the most recent intrinsic event. The persistent display is updated upon detection of a subsequent intrinsic event.

    Abstract: A method and system for mapping an anatomical structure includes sensing activation signals of intrinsic physiological activity with a plurality of electrodes disposed in or near the anatomical structure. Substantially similar activation signals are binned according to a self-correlation algorithm which identifies patterns among the sensed activation signals. A template is generated for each bin and compared to a characteristic template to identify at least one bin which corresponds to a far-field activation signal.
