摘要： A method includes, during arrhythmia occurrence, acquiring multiple sets of reference coronary sinus electrophysiological (CS-EP) signals with a first catheter in coronary sinus (CS) of a heart of a patient, while measuring multiple respective reference CS locations of the first catheter. One or more intra-cardiac electrophysiological (IC-EP) signals are acquired with a second catheter located in a cardiac chamber of the heart, while acquiring actual CS-EP signal with first catheter, and while measuring an actual CS location of first catheter. Using reference CS locations, reference CS-EP signal is identified whose reference CS location is nearest to actual CS location of the first catheter. A signal-stability measure between actual CS-EP signal and identified reference CS-EP signal is estimated. If signal-stability measure is above given threshold, identified reference CS-EP is utilized to verify whether the one or more IC-EP signals acquired by the second catheter are acquired during occurrence of the arrhythmia.

摘要： Methods, apparatus and computer software products implement embodiments of the present invention that include applying energy to a probe that is in contact with tissue in a body cavity so as to ablate the tissue. While applying the energy, signals are received from a location transducer in the probe, which are indicative of a location of the probe in the cavity. The signals are processed so as to derive 3D location coordinate points corresponding to the location of the probe at a sequence of times during which the energy was applied. While applying the energy, a 3D representation of the body cavity is rendered to a display, and visual indicators are superimposed on the 3D representation, the visual indicators corresponding to the 3D location coordinate points at the sequence of times. Finally, a linear trace connecting the coordinate points in accordance with the sequence is superimposed on the 3D representation.

摘要： A method includes receiving two or more surface representations of at least a portion of an organ of a patient. The two or more received surface representations are registered one with the other. One of the surface representations is selected as a base map. A draggable geodesic region is generated for at least one of the two or more surface representations not selected as a base map, wherein the geodesic region is configured to follow varying anatomy as the region is dragged over the base map. The draggable geodesic region is overlaid on the base map to generate a mixed multilayer representation, and the mixed multilayer representation is presented to a user.

摘要： A system includes a display and a processor. The processor is configured to: (i) estimate, based on signals, multiple regions of tissue on a surface of an organ, which are affected by multiple respective electrodes positioned in the organ, (ii) calculate, for at least a subset of the electrodes, a unified region of the tissue affected by the subset, and (iii) display a mark indicative of the unified region on the display.

摘要： A system including a medical device to form a 3D image of an anatomical structure in a body of a living subject, a user interface including a display and an input device, and a processor to prepare a user interface screen presentation including a graphical representation of the anatomical structure based on the 3D image, generate a feature list of a plurality of features associated with the anatomical structure, each feature having a respective location, render the user interface screen presentation to the display showing a first view of the graphical representation, receive an input from the user interface selecting a feature from the list, and render the user interface screen presentation to the display showing the graphical representation of the anatomical structure being automatically rotated from the first view to a second view showing the selected feature at the respective location on the graphical representation.
