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.

Abstract: An anatomical mapping system includes a plurality of mapping electrodes, a plurality of mechanical sensors, and a mapping processor associated with the plurality of mapping electrodes and mechanical sensors. The mapping electrodes are configured to detect electrical activation signals of intrinsic physiological activity within an anatomical structure. The mechanical sensors are configured to detect mechanical activity associated with the intrinsic physiological activity. The mapping processor is configured to record the detected activation signals and associate one of the plurality of mapping electrodes and mechanical sensors with each recorded activation signal. The mapping processor is further configured to determine activation times of the intrinsic physiological activity based on a correlation of corresponding electrical activation signals and mechanical activity.
