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.

Myocardial analysis apparatus and myocardial excitation detection apparatus

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 sectionwhich acquires an intracardiac electrocardiogram of a subject; a processing sectionwhich computes to produce visualized data indicating a state of excitation in the myocardium, based on the intracardiac electrocardiogram; and a determining sectionwhich determines the type of excitation dynamics of the myocardium based on the visualized data.

Myocardial excitation determining apparatus

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.

Bio-information analysis device

An RI measurement/notification apparatus includes: a displaying section configured to display waveform data of an intracardiac electrocardiogram; a waveform data acquiring section configured to acquire waveform data in a preset waveform data acquisition time period from an intracardiac electrocardiogram during atrial fibrillation; an RI calculating section configured to calculate an RI value based on the waveform data acquired by the waveform data acquiring section; and a notifying section configured to, in a case where the RI value calculated by the RI calculating section exceeds a preset threshold, notify that the value exceeds the threshold.
