Abstract
Abstract 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 fluoro angles can be obtained, and various images can be recorded, stored and printed. The position of a roving electrode can also be indicated.
