Visualization of electrophysiology data

A system for visualization of physiological information, comprising:

• means for storing electroanatomic data in memory, the electroanatomic data representing electrical activity on a surface of an organ over a time period, the electroanatomic data representing electrical activity on a surface of an organ over a time period, wherein the electroanatomic data for the predetermined region of the surface of the organ is computed by applying an inverse method based on patient electrical data for the patient acquired via non-invasive body surface electrodes and geometry data;
• means for selecting an interval within the time period in response to a user selection;
• means for applying at least one other method to the electroanatomic data for the user selected interval in response to the user selection of the interval and for generating output data;
• and
• means for generating a visual representation of physiological information for the user selected interval based on the output data, the visual representation being spatially represented on a graphical representation of a predetermined region of the surface of the organ.

A non-transitory computer readable medium having instructions for performing a method comprising:

• storing electroanatomic data in memory, the electroanatomic data representing electrical activity on a surface of an organ over a time period, wherein the electroanatomic data for the predetermined region of the surface of the organ is computed by applying an inverse method based on patient electrical data for the patient acquired via non-invasive body surface electrodes and geometry data, wherein the electroanatomic data corresponds to simultaneous electrical activity that is time indexed over the time period for each of a plurality of points distributed across the predetermined region of the surface of the organ;
• selecting an interval within the time period in response to a user selection, wherein the user selection specifies the interval with respect to a waveform representing electrical activity for a given location on the surface of the organ corresponding to the electroanatomic data;
• and
• generating a visual representation of physiological information based on the user selected interval by applying at least one other method to the electroanatomic data, the visual representation being spatially represented on a graphical representation of a corresponding region of the organ.

A non-transitory computer readable medium having instructions for performing a method comprising:

• preprocessing electrical data acquired from a patient, the preprocessing including selecting at least one sample interval for the acquired electrical data in response to a user input;
• generating electroanatomic data from the acquired electrical data for the selected at least one sample interval, the electroanatomic data representing electrical activity on a surface of an organ over a time period defined by the at least one sample interval;
• selecting an analysis interval within the time period in response to a user selection via a user interface, wherein the user selection specifies the analysis interval with respect to a representation of a waveform of electrical activity for a given location on the surface of the organ;
• responsive to the selection of the analysis interval, generating a visual representation of physiological information for the analysis interval by applying at least one method to the electroanatomic data that is generated based on the acquired electrical data for the at least one sample interval, such that the visual representation is variable and responsive to modifications in the analysis interval based on the user selection thereof while the at least one sample interval remains fixed, the visual representation of physiological information for the analysis interval being spatially represented on a graphical representation of a corresponding region of the surface of the organ.
