    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.

    Abstract: An anatomical mapping system and method includes mapping electrodes configured to detect activation signals of cardiac activity. A processing system is configured to record the detected activation signals and generate a vector field for each sensed activation signal during each instance of the physiological activity. The processing system determines an onset time and alternative onset time candidates, identifies an initial vector field template based on a degree of similarity between the initial vector field and a vector field template from a bank of templates, then determines an optimized onset time for each activation signal based on a degree similarity between the onset time candidates and initial vector field template.
