Title:
RECORDING DEVICE, RECORDING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/153175
Kind Code:
A1
Abstract:
A recording device includes: an acquisition unit (102) configured to acquire vital signs through a multi-electrode catheter (X) having a plurality of electrodes; a recording unit (104) configured to record a bipolar potential of a main channel which is defined by combining the plurality of electrodes, using the vital signs; an addition unit (32) configured to add a mark to each waveform plotted based on a potential of the bipolar potential, at a predetermined position on a time axis; and an adjusting unit (33) configured to adjust a position of the mark added to each waveform. The adjusting unit (33) is configured to adjust the position of the mark added to the bipolar potential of the main channel, based on bipolar potentials of reference channels including electrodes included in the main channel.
