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.

Recording device, recording method, and program

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.

Display control device and operation method of display control device

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 medical treatment support system has operations A to G on a display screen to easily handle respective data on a sheet. Operation A facilitates the browsing of a large amount of data. Operations B and C allow the user to easily copy and move data. Operation D is a scale function to facilitate measurement. Using operation E, the operator can easily divide an area into segments only by drawing a horizontal line. Operation F is used to change a display angle of image data displayed on the screen. Operation G allows the user to browse respective data classified for each sheet label. The new functions of the single-unit input/output pen-tablet device can be intuitively operated by a user not versed in the functions. This consequently mitigates the load of complex input operation which interrupts thinking of the user and which hinders diagnosis mitigated in medical treatment. A medical treatment support system, a display method for the same, and a recording medium having stored the same provide, in the processing of information regarding medical treatment, advantages of electronic data processing and advantages of processing of handwritten data on a sheet of paper.

Method for supporting medical treatment system and medical treatment support system

Disclosed is an electronic record system which dispenses with complicated operations using a menu and a button and handwriting input operation like paper writing can be achieved. A system is established and is provided with: an input/output unit device capable of inputting/outputting data by the direct writing on a display screen with a pen; and a control/arithmetic device connected to the input/output unit device and reflecting the data inputted on the display screen to the screen. In this system, an electronic record in the form of strip-shaped sheet with an infinite length extending in the longitudinal direction is displayed, data is directly inputted from the display screen as a stroke data, the inputted characters are converted into the character data by the use of a character recognition engine and the converted data is used as data format available in a secondary use such as a data search, and various functions are driven by a predetermined pen operation.
