Abstract:
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.
