Abstract
A recording device includes an acquisition unit configured to acquire vital signs through a sensor device having a plurality of electrodes, a recording unit 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 configured to add a mark to each waveform plotted based on variation of the bipolar potential over time, at a predetermined position on a time axis, and an adjusting unit configured to adjust a position of the mark added to each waveform. The adjusting unit 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.

Abstract
A myocardial excitation complementation/visualization apparatus includes an acquiring section that acquires intracardiac electrocardiograms of a subject, the intracardiac electrocardiograms being recorded by a recording unit having a plurality of electrodes, a processing section that performs a computation for completing and visualizing a state of excitation in a myocardium of the subject based on the intracardiac electrocardiograms, and a displaying section that displays the state of excitation in the myocardium of the subject based on an output of the processing section. The processing section includes a first generating section, a correcting section, a second generating section, and a third generating section. The displaying section displays a change of the state of excitation in the myocardium of the subject based on the visualized data.

Abstract
A myocardial excitation determining apparatus which can support the determination of excitation dynamics of the myocardium during atrial fibrillation is provided. A myocardial excitation determining apparatus has: an acquiring section 2 which acquires an intracardiac electrocardiogram of a subject; a processing section 3 which computes to produce visualized data indicating a state of excitation in the myocardium, based on the intracardiac electrocardiogram; and a determining section 4 which determines the type of excitation dynamics of the myocardium based on the visualized data.
