摘要： In one embodiment, a medical system includes a catheter to be inserted into a chamber of a heart, and including electrodes to capture electrical activity of tissue of the chamber over time, a display, and processing circuitry configured to compute a propagation of a cardiac activation wave over an anatomical map of the chamber from a start time in a cardiac cycle to an end time in the cardiac cycle responsively to the captured electrical activity, render to the display a sub-region of the anatomical map, select a time-bounded portion of the propagation of the cardiac activation wave commencing at a time after the start time responsively to when the propagation would commence to be rendered in the sub-region of the anatomical map, and render to the display the time-bound portion of the propagation of the cardiac activation wave on the sub-region of the anatomical map.

摘要： A method is provided. The method is implemented by a device orientation engine being executed by one or more processors. The method includes determining a movement between each electrode group of a catheter to provide movements and determining a total movement of electrodes of the catheter. The method also includes removing a standard component from the movements and the total movement and outputting a movement indication for the catheter based on the movements and the total movement with the standard component.

摘要： Systems and methods are disclosed for linking a point-list to a three-dimensional anatomy of the heart. Techniques disclosed include recording a point-list, where each entry in the point-list comprises data elements, and is associated with a location in the heart and a measurement. The associated measurement is acquired by an electrode of a catheter that is placed at the associated location in the heart. Techniques disclosed further include selecting one or more anchor points associated with a region of interest in the heart, then, for each entry in the recorded point-list, computing a data element of distance between the entry's associated location in the heart and the selected one or more anchor points, and manipulating entries in the point-list based on their respective data elements.

摘要： A system includes a display and a processor. The display is configured to display at least a map of an organ having tissue including first and second surfaces that are facing one another. The processor is configured to: (i) receive a first position of a first lesion formed by ablating the first surface, (ii) calculate on the second surface, a second position that is facing the first position, and (iii) display, over the map, a marker indicative of the second position for guiding a user to produce in the tissue a second lesion facing the first lesion.

摘要： A method for identifying candidate locations for ablation includes receiving an electrophysiological (EP) map comprising anatomical surface of cardiac chamber overlaid with (i) activation wave velocity vectors, (ii) data points comprising positions on surface and respective local activation times (LAT), and (iii) areas designated by early meet late (EML) LAT range. Set of shortest paths on cardiac surface is identified between different EML areas. One or more ranges of LAT values are selected, being characterized by lowest prevalence over data points of EP map. Complex tags are generated for positions having the LAT values within the one or more ranges of LAT values having lowest prevalence. Subset of the shortest paths is selected based on (i) density of complex tags along shortest paths and (ii) directions of activation wave velocity vectors relative to each of shortest paths. Selected subset of shortest paths are presented as candidate slow-conduction areas for ablation.

摘要： A system and method for clustering wavefront signals in an electrophysiological map of a cardiac tissue are provided. The system and method include receiving an electrophysiological map of the cardiac tissue, displaying propagation of the wavefront signals as a plurality of velocity vectors, discretizing the received electrophysiological map into a plurality of sections, clustering the velocity vectors into at least one group within each section based on predefined criteria, and generating a trend line representative of each group of clustered velocity vectors within each section in the electrophysiological map.

摘要： A system includes an interface and a processor. The interface is configured to receive multiple electrophysiological (EP) signals from a tissue area along an ablation curve inside a cardiac chamber of a heart of a patient. The processor is configured to (i) generate local conduction vectors (LCVs) for the area based on the multiple EP signals, (ii) estimate a level of change between sets of LCVs along the ablation curve within the tissue area, and (iii) based on the level of change, identify a presence of a conduction gap in the ablation curve.#
