摘要：

Provided are a myocardial excitement interpolation/visualization device with which a state of myocardial excitement can be viewed in real time, and a myocardial excitement detection device with which sites of myocardial excitement can be detected more accurately. The device is provided with an acquisition unit (2) for acquiring an intercardiac electrocardiogram recorded by multiple electrodes, a computing unit (3) for performing computations to interpolate and visualize a state of myocardial excitement on the basis of the intercardiac electrocardiogram, and a display unit (4) for displaying the state of myocardial excitement. The computational unit (3) has a first generation unit (11) for generating an action potential waveform for each of a plurality of intercardiac electrocardiograms, a correction unit (13) for performing correction to harmonize the amplitudes of each unit waveform included in the action potential waveforms, a second generation unit (14) for generating shift waveforms differing in time phase from the corrected action potential waveforms, and a third generation unit (16) for creating phase diagrams on the basis of the corrected action potential waveforms and the shift waveforms, and generating visualization data representing a state of myocardial excitement in a test subject, on the basis of the phase diagrams. The display unit (4) displays changes in the state of myocardial excitement of a test subject, on the basis of the visualization data.L'invention concerne un dispositif de visualisation/interpolation de l'excitation du myocarde à l'aide duquel un état d'excitation du myocarde peut être visualisé en temps réel, et un dispositif de détection de l'excitation du myocarde à l'aide duquel des sites d'excitation du myocarde peuvent être détectés avec plus de précision. Le dispositif est doté d'une unité d'acquisition (2) pour l'acquisition d'un électrocardiogramme intracardiaque enregistré par de multiples électrodes, d'une unité de calcul (3) pour
