Abstract: Devices, systems, and methods for visualizing a reference location of an electrophysiology device in an anatomical image are provided. According to one embodiment, an electrophysiological mapping and guidance system includes a processor circuit in communication with a catheter carrying a plurality of electrodes. The processor circuit controls the plurality of electrodes to obtain electrical measurements (e.g., voltage measurements) of an electrical field induced within an anatomical cavity. The processor circuit computes a reference location of the plurality of electrodes based on distortions in the electromagnetic field detected at a first time, computes a current location of the plurality of electrodes based on distortions in the electromagnetic field detected at a later second time, and outputs a signal to cause simultaneous display of a first visualization of the reference location and a second visualization of the current location.
