    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.

    Abstract: A system and method for mapping an anatomical structure includes sensing activation signals of physiological activity with a plurality of mapping electrodes disposed in or near the anatomical structure. Patterns among the sensed activation signals are identified based on a similarity measure generated between each unique pair of identified patterns which are classified into groups based on a correlation between the corresponding pairs of similarity measures. A characteristic representation is determined for each group of similarity measures and displayed as a summary plot of the characteristic representations.

    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: Electrical activity propagation along an electrode array within a cardiac chamber is reconstructed. Signals are sampled from the electrode array including signals from a channel of interest. An N-dimensional signal vector is then constructed using signals from N neighboring channels referenced to the channel of interest. A change in the N-dimensional signal vector over time is then determined and compared to a predetermined threshold to establish whether local activation has occurred on the channel of interest.
