摘要: Systems and methods can be used to provide an indication of heart function, such as an indication of mechanical function or hemodynamics of the heart, based on electrical data. For example, a method for assessing a function of the heart can include determining a time-based electrical characteristic for a plurality of points distributed across a spatial region of the heart. The plurality of points can be grouped into at least two subsets of points based on at least one of a spatial location for the plurality of points or the time-based electrical characteristics for the plurality of points. An indication of synchrony for the heart can be quantified based on relative analysis of the determined time-based electrical characteristic for each of the at least two subsets of points.

摘要: A method can include providing (302) at least one parameter to control a therapy that is applied to at least one internal anatomical structure of a patient. Electrical data can be obtained from the patient (304), including electrical data acquired via a plurality of sensors during each of a plurality of iterations of the therapy. The electrical data can be analyzed (306) for a respective value of the at least one parameter of the therapy at each of the plurality of iterations of the applied therapy to compute an indication of at least one function of the at least one internal anatomical structure of the patient at each respective iteration of the applied therapy.

摘要: Systems and methods can be utilized to visualize physiological data relative to a surface region (e.g., an organ) of a patient. A computer-implemented method can include storing electroanatomic data in memory representing electrical activity for a predetermined surface region of the patient and providing an interactive graphical representation of the predetermined surface region of the patient. A user input is received to define location data corresponding to a user-selected location for at least one virtual electrode on the graphical representation of the predetermined surface region of the patient. A visual representation of physiological data for the predetermined surface region of the patient is generated based on the location data and the electroanatomic data.

摘要: A method for visualization of electrophysiology information can include storing electroanatomic data (14) in memory, the electroanatomic data representing electrical activity on a surface of an organ over a time period. An interval within the time period is selected in response to a user selection (28). Responsive to the user selection of the interval, a visual representation (26) of physiological information for the user selected interval is generated by applying at least one method to the electroanatomic data (14). The visual representation (26) is spatially represented on a graphical representation of a predetermined region of the surface of the organ.

摘要: A system (10) can localize an object in a patient's body. The system (10) can include a pulse generator (18 or 30) configured to provide a localization signal to at least one electrode that is fixed to the object in the patient's body. A sensor array (22) can be configured to detect an electrical field produced in response to the localization signal and provide respective sensor signals. A map generator (42) can be configured to reconstruct electrical signals based on the respective sensor signals and geometry data representing a geometric relationship between patient anatomy and the sensor array. A location calculator (50) can determine a location where the localization signal was applied based on the reconstructed electrical signals.
