DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. (First Embodiment of the Invention) FIG. 1 is a block diagram showing a configuration of a heart movement display device capable of displaying a heart movement according to an embodiment of the invention according to the present invention. In FIG. 1, reference numeral 1 denotes a ROM stored in a ROM 2, for example, FIG.
The CPU 2 controls the overall control of the present embodiment according to the control procedure shown in FIG.
M and 3 are RAMs for temporarily storing the progress of various processes and the like.
Reference numeral denotes a display unit for displaying an electrocardiogram signal and a waveform indicating the movement of the heart together with an explanation of the state of the heart. Reference numeral 5 denotes a display control unit for controlling display of the display unit 4;

A heart state memory 20 stores the state of the heart corresponding to the electrocardiogram waveform as an image. The state of the heart is imaged and stored as a cross section of the heart together with the stimulation conduction system. Reference numeral 30 denotes an electrocardiogram memory which stores electrocardiogram waveforms corresponding to the respective heart conditions and explanatory texts explaining the heart conditions. The cardiac state display control according to the present embodiment having the above-described configuration will be described below with reference to the flowchart of FIG.

When the heart condition display control of the CPU 1 is started, the process of step S1 in FIG. 2 is executed. For example, a menu screen (initial selection screen) shown in FIG. On this menu screen, a list of heart conditions that can be displayed in the present embodiment is displayed. By selecting a desired display item from this list, the heart condition of the selected item can be displayed.

That is, "normal sinus rhythm", "left ventricular hypertrophy", "right ventricular hypertrophy", "complete right leg block", "complete left ventricular block", and "2: 1 atrioventricular" indicating normal heart movement. Block, complete atrioventricular block, supraventricular extrasystole, ventricular extrasystole, WPW (Wolff-Parkinson-Levin)
e) ”,“ Atrial fibrillation ”,“ Coronary circulation ”,“ Angina pectoris ”,“ Mechanism of myocardial infarction ”,“ Part of myocardial infarction ”,“ Myocardial infarction time series ”shows 16 items of cardiac status display It is configured to be possible.

In this embodiment, electrocardiogram information and cardiac state display corresponding to 16 types of cardiac states are possible. However, this heart condition is not limited to the 16 types shown in FIG. 3, and it is needless to say that many more types of heart conditions can be displayed. For example, the ventricle hypertrophy is further subdivided, and the left atrium and right ventricular hypertrophy, the right atrium and right ventricular hypertrophy, the left atrium and left ventricular hypertrophy, the right atrium and left ventricular hypertrophy, etc. are associated with the atrial hypertrophy. What is necessary is just to set more detailed items such as an electrocardiogram and a heart condition.

The operator selects a desired heart condition from the menu screen in step S1, and clicks a heart condition menu to be selectively displayed with a mouse or the like. When it is desired to know the patient's heart condition, for example, the patient's heart condition is analyzed in advance by analyzing the patient's measured electrocardiogram signal using an electrocardiograph or the like, or referring to the electrocardiogram's electrocardiogram analysis result. Judgment is performed, and processing such as selection is performed according to the judgment result.

Therefore, it is monitored in step S2 that this selection input is made. When the selection input is performed, the process proceeds from step S2 to step S3, and a screen display of the selected heart state is performed. FIG. 4 shows an example of a selection screen when “normal sinus rhythm” is selected. As shown in FIG. 4, the selection screen is roughly divided into three displays, a heart state display area for displaying the state of the heart in the upper left as cross-sectional image information including the stimulus conduction system, and a lower part of the heart state display area. It comprises an electrocardiogram waveform display area, a heart state display area, and a comment information display area on the right side of the electrocardiogram waveform display area, which describes the state of the selected heart.

The heart condition in the electrocardiogram waveform display area is as follows.
The stimulus conduction system is also displayed, and the stimulus conduction state and the myocardial operation state are displayed so as to be recognizable. Further, in the present embodiment, since the description of the heart condition is displayed in association with the display of the heart condition, the understanding of the heart condition is further deepened. For example, the present device was used as a teaching material for school. In some cases, a high learning effect can be obtained, and a high learning effect can be expected even by self-study by selecting and selecting various selection screens.

In addition, a selection screen change instruction input area for instructing a transition from this processing screen to another screen display ("Next" for transitioning to the next selection screen and an instruction for transition to an initial screen) are provided in the upper part. "Menu" is provided), and an adjustment instruction input area for a display change speed of an electrocardiogram waveform and a heart state provided below the electrocardiogram waveform display area. The adjustment instruction input area is a speed adjustment unit for adjusting the speed of change of the electrocardiogram waveform and the heart state on the right side (the speed is reduced by one step by inputting the slow key, and the speed is increased by one step by inputting the fast key. The speed is indicated by a black circle in the center.) And a progress key for setting the display of the electrocardiogram waveform and the heart state to a progress mode to be described later, and whether to return to the display one screen before or to display one screen later. It consists of a step display key for instructing. In addition,
In the series of FIG. 4, the progress key is displayed because the stop mode is not the deep-depth mode. However, in the case of the sea urchin progress mode described later, the display is changed to the stop key for stopping the progress.

In the electrocardiogram waveform display area, a standard electrocardiogram waveform in the state of the selected heart is lightly displayed, and this thinly displayed electrocardiogram waveform is sequentially measured during display control of an electrocardiogram waveform described later. The display gradually changes to a darker display as if it were performed. In the heart condition display area, the heart condition without stimulation in the heart condition selected from the heart condition memory 20 is read and displayed. In the initial display state of the selection screen, the heart state display speed is set to an initial value. That is, the speed setting in the adjustment instruction input area is set to just the intermediate value. This setting state is the state shown in FIG.

In the subsequent step S4, it is checked whether or not the progress mode in which the display of the electrocardiogram waveform and the heart condition is sequentially updated is set. The progress mode is a mode in which the set heart condition display is advanced at a speed specified by the heart condition display speed, and the display of the corresponding heart condition is updated. The state in FIG. 4 is a display example when the progress mode is not set, and a progress key (center key) is displayed in the adjustment instruction input area.

If the advance mode has been set in step S4, the process proceeds to step S5, in which the display of the electrocardiogram waveform corresponding to the heart condition selected from the electrocardiogram memory 30 is sequentially read out at the set speed, and the electrocardiogram waveform is displayed. Change the display to a dark waveform display. At the same time, the state of the heart at the current position of the electrocardiogram waveform is stored in the heart state memory 20.
It is read out and displayed in the heart condition display area. Then, the process proceeds to step S10.

As a display example of step S5, for example,
At the output timing of the P-wave of the electrocardiogram waveform, atrial depolarization has occurred as a cardiac condition, and the sinus node has been excited, and this excitation has been transmitted to the atrioventricular node via three internodal paths in the atria. The state is being transmitted, and a display example of this state is shown in FIG. In addition, at the generation timing of the R wave in the electrocardiogram, the excitement reaches the anterior wall septum beyond the atrioventricular node via the His bundle from the atrioventricular node via the left and right legs of the ventricular septum.
FIG. 6 shows a state immediately before transmission to the rkinje system. FIG. 7 shows a state in which a T wave is generated due to repolarization of the ventricle and the ventricle is in a contracted state.
Shown in

As shown in FIG. 5 to FIG. 7, by displaying the movement of the heart in a time series by associating the electrocardiogram waveform with the heart state, the electrocardiogram and the heart state can be extremely easily associated with each other. Can be recognized. On the other hand, step S4
If the mode is set to the progress mode, the process proceeds to step S6, and it is determined whether or not a progress key in the adjustment command input area is input and an instruction to shift to the progress mode is input. If there is an input of the progress key, the process proceeds to step S5 described above,
If there is no progress key input, the process proceeds to step S10.

In step S10, it is determined whether or not there is a speed change instruction input on the right side of the adjustment instruction input area, that is, a "slow" key for setting to decrease the speed or a "fast" key for setting to increase the speed. Check to see if there is an input. If there is a speed change input, the process proceeds to step S11, and the progress speed is changed by one step corresponding to the input key. If the input is a "slow" key, the progress speed is set to be slow by one step, and the display is also moved to the slow side by one step. If the input is the "fast" right arrow key, the advance speed is set faster by one step, and the display is also moved to the fast side by one step. Then, the process proceeds to step S4.

On the other hand, if the input is not a speed change input in step S10, the flow advances to step S12 to check whether a pause key, which is a middle key on the left side of the adjustment instruction input area, has been input. When the pause key is input, the process proceeds to step S13, in which the progress mode in which the display of the electrocardiogram waveform and the heart condition is sequentially updated is changed to the stop mode, and the display state at the time of key input is fixed and the electrocardiogram waveform and Stop updating the display of the heart condition. Then, the process proceeds to step S4.

On the other hand, if the pause key in the adjustment instruction input area has not been input in step S12,
Proceeding to 14, it is checked whether or not there is a display state section change instruction in the adjustment instruction input area. If there is an instruction to change the display state part of the adjustment instruction input area, the process proceeds to step S15, where the left and right display states on the left side of the adjustment instruction input area are finely changed (one step before or at the advanced timing of the electrocardiogram waveform and the heart state). Display). Then, the progress mode is changed to the stop mode, and the process proceeds to step S4.

When the left arrow key on the left side is input, the display state is changed to the display state of the electrocardiogram signal one step before, and the heart state is changed to the heart state corresponding to the electrocardiogram waveform (display before one step). When the right arrow key is pressed, the display state is changed to the display state of the electrocardiogram signal advanced by one step, and the heart state is changed to the heart state corresponding to the electrocardiogram waveform (display after one step).

On the other hand, if there is no instruction to change the display state portion of the adjustment instruction input area in step S14, the flow advances to step S16 to determine whether "Next" for shifting to the next selection screen in the selection screen change instruction input area has been instructed. Find out what. If "Next" in the selection screen change instruction input area has been input, the process proceeds to step S17, where the next screen is selected as the selection screen because it is an instruction to select the next selection screen after the current selection screen.
Proceed to. The selection of the next selection screen is performed in the order of the number given to the head of each heart condition on the menu screen shown in FIG. 3, and the next to the last number is the first selection screen.

On the other hand, if there is no selection screen change instruction in step S16, the flow advances to step S18 to determine whether or not "Menu" in the selection screen change instruction input area for instructing return to the initial screen has been input. If "Menu" has been input, the process returns to step S1, and if "Menu" has not been input, the process returns to step S4. As described above, according to the embodiment of the present invention, the electrocardiogram waveform and the state of the heart are displayed as images in association with each other.
