Abstract: Electrical activity propagation along an electrode array within a cardiac chamber is reconstructed. Signals from the electrode array are sampled, and the signals are plotted in multi-dimensional space with each axis corresponding to a channel in the electrode array. A covariance matrix of the plotted signals is decomposed to characterize the spread of a data cloud of the signals in the multi-dimensional space. The data cloud is then decorrelated, such as through whitening, to suppress excursions along correlated directions (global activation) and enhance excursions along each axis (local activation).

Abstract: Electrical activity propagation along an electrode array within a cardiac chamber is reconstructed. Signals are sampled from the electrode array and the signals are plotted in multi-dimensional space with each axis corresponding to a channel in the electrode array. An excursion direction of global activation in the multi-dimensional space is estimated and a change in vectors of the sampled signals over time is determined. Signals with vectors that change over time in the excursion direction are suppressed.

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: 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.
