  • DISPLAY CONTROL DEVICE AND OPERATION METHOD OF DISPLAY CONTROL DEVICE
    Publication number: 20220296153
    Abstract: A display control device includes processing circuitry configured to: obtain an intracardiac electrocardiogram of a subject; generate visualization data representing an excitation state of a myocardium based on the intracardiac electrocardiogram; determine a type of excitation dynamics of the myocardium based on the visualization data; and display, on a stereoscopic image of a heart of the subject, a site from which the intracardiac electrocardiogram is obtained with a color in accordance with a ratio of the determined type of the excitation dynamics.

  • CARDIAC CATHETER INSPECTION APPARATUS, CARDIAC CATHETER INSPECTION SYSTEM, AND CARDIAC CATHETER INSPECTION METHOD
    Publication number: 20180289278
    Abstract: A cardiac catheter inspection apparatus comprising: an acquiring section (31) which is configured to acquire a first waveform of heart beats during sinus rhythm, and an arrhythmia waveform during arrhythmia; a measuring section (31) which is configured to measure a second electrocardiogram; a first calculating section (32) which is configured to calculate correction coefficients for statistically matching the first electrocardiogram and the second electrocardiogram with each other; a waveform producing section (34) which is configured to produce a comparison waveform that functions as an object to be compared with a response waveform of pacing performed by a cardiac catheter; and a second calculating section (36) which is configured to calculate a matching rate of the response waveform and the comparison waveform.

  • Bio-information analysis device
    Patent number: 9782100
    Abstract: A bio-information analysis device includes a measuring unit that measures biometric waveforms of a subject, and a calculating unit that calculates a matching rate of the biometric waveforms based on shapes and magnitudes of the biometric waveforms measured by the measuring unit. In the bio-information analysis device, the biometric waveforms may be electrocardiogram waveforms.
