| 1. 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.
