    Abstract: An electroanatomical mapping system can map electrical activation of tissue, and in particular create a slow conduction map, using a plurality of electrophysiology data points, each including local activation timing information, by computing a slow conduction metric for each point using the local activation timing information. The slow conduction metric can be used to classify points as no conduction points, slow conduction points, and normal conduction points, and the results can be graphically expressed, including as an animated representation of an activation wavefront propagating along a three-dimensional anatomical surface model.

    Abstract: A computer-based visualization method includes: arranging, based on electrocardiogram data that indicates an electrocardiogram obtained by sensing from a patient in a predetermined period, a plurality of curves in time series in an axial direction perpendicular to a time axis and a potential axis of the electrocardiogram, each of the plurality of curves indicates a partial electrocardiogram corresponding to a respective beat from among the electrocardiogram indicated in the electrocardiogram data; generating a curved surface that includes the plurality of arranged curves; generating a plane that intersects the curved surface; and outputting a figure based on an intersection line between the curved surface and the plane.

    Abstract: Various embodiments include methods and computing systems for arrhythmia localization and display. A computing system may select a 3D heart electrical conduction model, including a 3D surface model, from a database of representative 3D heart models based on patient demographic information. The computing system may generate a patient-specific 3D localization of an arrhythmia based on the selected 3D electrical conduction model and ECG data, and generate a patient-specific cardiac activation map based the 3D electrical conduction model and ECG data. The computing system may then merge the patient-specific 3D localization of the arrhythmia and the 3D surface model to generate a 3D arrhythmia activation surface model, and display the patient-specific 3D localization of the arrhythmia and the patient-specific cardiac activation map for use in a medical procedure. Patent demographic information may be used to create or adjust a 3D heart model for inclusion in the database.

    Abstract: A method, including receiving, from electrodes positioned within a heart, first signals from at least three of the electrodes indicating electrical activity in tissue with which the at least three of the electrodes engage, and second signals indicating locations of the at least three electrodes. The second signals are processed to compute the locations of the at least three electrodes and to determine a geometric center of the locations. Based on the signals, an electroanatomical map is generated for an area of the tissue including the geometric center, and an arrhythmia focus is determined in the map. A circle is presented, and within the circle, a region of the map is presented including the geometric center and the focus so that the geometric center on the map aligns with a center of the circle, the region within the circle indicating a spatial relationship between the geometric center and the focus.

    Abstract: Disclosed are various examples and embodiments of systems, devices, components and methods configured to provide enhanced resolution electrographic flow (EGF) spatial maps of a patient's heart, and subsequently to detect at least one location or type of at least one source, rotational phenomenon, or slow electrical conduction zone or area associated with at least one cardiac rhythm disorder within such maps. Data acquired using intracardiac electrodes and/or body surface electrodes are used in conjunction with EGF techniques to generate an enhanced resolution map corresponding to a spatial map. The enhanced resolution map is configured to reveal on a monitor or display to a user the at least one location or type of the at least one source, rotational phenomenon, or slow electrical conduction zone or area associated with at least one cardiac rhythm disorder.

    Abstract: A medical system for creating a communication channel between two anatomical structures includes an outer member having a proximal portion and a distal portion, and a lumen extending from the proximal portion to the distal portion. At least a portion of the lumen includes an electrically conductive surface extending to a distal end of the distal portion. The system includes an inner member having a proximal portion and a distal portion. The inner member is configured to translate within the lumen and to deliver a therapy to target tissue. The inner member distal portion includes a conductive distal tip configured to electrically couple with the electrically conductive surface of the outer member. The inner member includes a proximal portion adapted to electrically couple the conductive distal tip to an auxiliary device.
