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 method includes receiving, for at least a region of an anatomical map of at least a portion of a heart, positions and respective electrophysiological (EP) wave propagation velocity vectors, the vectors having respective magnitudes. The magnitudes are nonlinearly scaled. Scaled vectors having the scaled magnitudes, are presented by being overlaid on the anatomical map.

摘要： A method includes, inserting a catheter into a cavity of a patient organ for performing a medical procedure, the cavity is of a given cavity type. A partial anatomical mapping of the cavity is performed by visiting one or more anatomical points on a surface of the cavity, using the catheter. Based on the partial anatomical mapping, a Graphical User Interface (GUI) template is selected, which is specified for applying the medical procedure to the given cavity type. The selected GUI template is presented to a user for performing the medical procedure in the cavity.

摘要： A method includes receiving a plurality of data points including electrical activation (EA) values measured at respective positions in at least a portion of a surface of a cardiac chamber of a heart of a patient. Using a predefined EA value criterion, the EA values in a given region of the cardiac surface are classified into multiple distinct EA wave-fronts, and multiple layers of EA values are calculated for the given region, wherein each EA layer includes the EA values found to belong to a respective and contiguous EA wave-front. The multiple EA layers are overlayed on a graphical representation of the surface. The graphical representation with the multiple overlaid EA layers is displayed to a user, with a graphical indication distinguishing between the multiple EA layers.

摘要： Various embodiments are described herein for a bipolar catheter that generally comprises: a catheter body having a distal end portion and a proximal end portion; a first electrode at the distal end portion, the first electrode being on a spiral structure for rotational insertion into a physiological target region; a second electrode at the proximal end portion and spaced apart from the first electrode; and first and second electrode terminals spaced apart from one another at the proximal end portion and electrically coupled to the first and second electrodes respectively. The first and second electrodes are configured to function as active and dispersive electrodes respectively, or vice-versa. Also described are various embodiments of methods which generally include coupling the bipolar catheter to a signal generator; inserting the bipolar catheter at a physiological target region; and performing the procedure.

摘要： Systems and methods are disclosed for visualizing reentrant circuits in the heart via pseudo-activation maps. Techniques disclosed comprise receiving sets of ECG data and respective pacing sites. Each of the sets is generated by pacing heart tissue at a respective site of the pacing sites. Techniques disclosed further comprise computing correlation gradients representative of morphological changes across sets, of the sets of the ECG data, of respective neighboring sites of the pacing sites. Based on the computed correlation gradients, a core zone associated with a reentrant circuit is identified. Then, relative to the identified core zone, one or more pseudo-activation maps are generated.

摘要： A method includes receiving a plurality of data points including electrophysiological (EP) values measured at respective positions in at least a portion of an organ of a patient. Some of the EP values are classified as outlier values in accordance with a defined criterion. A visual representation of at least the portion of the organ is derived from the plurality of data points. The visual representation represents the EP values with respective colors, and visualizes less than all the outlier values, by performing one or both of (a) identifying outlier values that deviate from respective neighboring EP values by less than a defined deviation, and representing the outlier values using colors that match the neighboring EP values, and (b) setting for the visual representation a mapping, which maps the EP values to the colors and which excludes at least some of the outlier values.

摘要： Electroanatomic mapping is carried out by inserting a multi-electrode probe into a heart of a living subject, recording electrograms from the electrodes concurrently at respective locations in the heart, delimiting respective activation time intervals in the electrograms, generating a map of electrical propagation waves from the activation time intervals, maximizing coherence of the waves by adjusting local activation times within the activation time intervals of the electrograms, and reporting the adjusted local activation times.
