摘要： A method for mapping a body organ, including receiving a three-dimensional (3D) map of the body organ together with items of auxiliary information having respective location coordinates in a frame of reference of the 3D map and apportioning the items into a plurality of sub-groups. The method further includes assigning to a selected sub-group a visibility parameter indicative of a relative visibility of the selected sub-group in relation to the map and to other sub-groups. The method also includes displaying the 3D map of the body organ in a selected orientation while selectively superimposing on the 3D map one or more of the items in the selected sub-group responsively to the orientation, the respective location coordinates of the items, and the assigned visibility parameter.

摘要： A method includes obtaining multiple local activation times (LATs) at different respective measurement locations on an anatomical surface of a heart. The method further includes computing respective directions of electrical propagation at one or more sampling locations on the anatomical surface, by, for each sampling location, selecting a respective subset of the measurement locations for the sampling location, constructing a set of vectors, each of at least some of the vectors including, for a different respective measurement location in the subset, three position values derived from respective position coordinates of the measurement location and an LAT value derived from the LAT at the measurement location, and computing the direction of electrical propagation at the sampling location based on a Principal Component Analysis (PCA) of a 4x4 covariance matrix for the set of vectors. The method further includes indicating the directions of electrical propagation on a display.

摘要： A method includes, receiving, on a surface of an anatomical map of a patient organ having a first presentation, a selection of a first selected region, which is intended to have a second presentation, different from the first presentation. A perimeter of the first selected region, and at least an unselected area positioned within the first selected region, are identified. A second selected region is produced, the second selected region includes the first selected region and the unselected area. The anatomical map, having the second presentation applied to the second selected region, is displayed.

The method further includes, based on the LATs, computing respective directions of electrical propagation at the locations. The method further includes selecting pairs of adjacent ones of the electrodes such that, for each of the pairs, a vector joining the pair is aligned, to within a predefined threshold degree of alignment, with the direction of electrical propagation at the location of one of the electrodes belonging to the pair. The method further includes associating respective bipolar voltages measured by the pairs of electrodes with a digital model of the anatomical surface. Other examples are also described.
