Patent ID: 7596406

Claim:
A device for recording and displaying electrophysiological signals or signal information elements derived from electrophysiological signals, the device comprising: a catheter including a plurality of electrodes for acquiring electrophysiological signals, the plurality of electrodes having a distributed geometric arrangement on the catheter; and a display device for displaying the electrophysiological signals or the signal information elements, wherein the display device is configured to display the respective electrophysiological signals or the signal information elements in a display arrangement corresponding to the distributed geometric arrangement of the electrodes or corresponding to a current spatial geometric arrangement of the electrodes relative to a three-dimensional environment while acquiring the electrophysiological signals, wherein the electrophysiological signals are time domain signals acquired and displayed continuously in a time display where each of the plurality of electrodes has a corresponding time domain signal and all of the corresponding time domain signals are displayed simultaneously, and the signal information elements are determined by averaging an amplitude of a respective electrophysiological signal associated with a respective electrode, and where the signal information element is rendered in a color-coded manner and all of the corresponding signal information elements are displayed simultaneously and arranged in cake segments.
