A graphical user interface (GUI) is provided for assisting medical personnel in interpreting data collected by a multiple electrode catheter deployed within the body. The GUI generates and displays an image of the multiple electrode catheter. By manipulating appropriate controls, the medical personnel are able to change the orientation of the displayed image until it matches the orientation of the actual multiple electrode catheter as seen on a fluoroscope. Afterwards, the medical personnel can determine the relative position and orientation of the catheter by reference to the GUI generated image. To aid in interpreting data recovered by the catheter, the individual electrodes and splines are highlighted and labeled. Electrodes recovering particular types of physiological waveforms can be automatically identified and highlighted. Comments and anatomic landmarks can be inserted where desired to further assist in interpreting data. Views from various, virtual fluoroangles can be obtained, and various images can be recorded, stored and printed. The position of a roving electrode can also be indicated.

Graphical user interface for use with multiple electrode catheters

A system records use of a structure deployed in operative association with heart tissue in a patient. An image controller generates an image of the structure while in use in the patient. An input receives data including information identifying the patient. An output processes the image in association with the data as a patient-specific, data base record for storage, retrieval, or manipulation.

Systems for recording use of structures deployed in association with heart tissue

Systems and methods for locating an operative element within an interior body space use a locating probe, which includes at least one transmitting element to transmit an electric waveform output within at least a portion of the space. The systems and methods also use a sensing element, which is adapted to be carried by the operative element to sense a local electric waveform within the space. A processing element coupled to the sensing element generates a processed output that locates the sensing element relative to the locating probe based, at least in part, upon a differential comparison of the waveform output and the sensed local waveform.

Systems for recording use of structures deployed in association with

A system is used in association with a structure which, in use, is deployed in an interior body region. The structure includes an operative element. A switch matrix is coupled to the operative element. The switch matrix includes a plurality of inputs and a plurality of outputs. A controller is coupled to the switch matrix to control the switch matrix to couple the operative element to selected ones of the inputs and selected ones of the outputs in accordance with applied commands. An interface is coupled to the controller. The interface includes an input element to receive operator input and a processor to generate applied commands to the controller in response to operator input. The interface also includes an image controller to generate an image of the structure while coupled to the switch matrix. The image controller generates markers on the image in response to signals transmitted from the operative element through the switch matrix.
