A method for manipulating an electrocardiogram reference candidate image will be described with reference to FIG. Here, a description will be given using an example in which an ECG examination image 101g of reference candidate 7: 2009/02/02 is displayed on the share window 100.

  Among the images whose finding information is “tachycardia” on the share window 100, the nth electrocardiogram image 120 is displayed. At this time, the user operates the keyboard 20 of the image interpretation terminal 6 to display the (n−1) th or (n + 1) th “tachycardia” image. Or, according to the order determined by the display order of the finding information and the behavior information of the subject given in step S5 of the flowchart of FIG. 6, the partial ECG images accompanying the different finding information and the behavior information of the subject are displayed. Such as displaying an image showing the entire waveform. A detailed example of each operation will be described. For example, when the “↑” key (Up key) of the keyboard 20 is pressed while the nth electrocardiogram image 120 is displayed, the image 121 of the n−1th finding information “tachycardia” is shared. It is displayed on the window 100. When the “↓” key (Down key) of the keyboard 20 is pressed while the nth electrocardiogram image 120 is displayed, the image 122 of the (n + 1) th finding information “tachycardia” is displayed in the share window. 100 is displayed. Further, when the “←” key (Left key) of the keyboard 20 is pressed while the nth electrocardiogram image 120 is displayed, the image 123 of the finding information “ST rise” is displayed on the share window 100. . Further, when the “→” key (Right key) of the keyboard 20 is pressed while the nth electrocardiogram image 120 is displayed, an image 124 of the finding information “bradycardia” is displayed on the share window 100. . When the “Home” key on the keyboard 20 is pressed while the nth electrocardiogram image 120 is displayed, the entire image 125 is displayed on the share window 100. The key pressed in each operation may be changed by setting, or the operation method may be changed so that the mouse 19 can be operated as an alternative to the keyboard 20.

(Use Case U2)
When the share window 100 is displayed on the screen display device 6a, the user performs another mouse operation by pressing the ECG extended display button 102 shown in FIG. An electrocardiogram image can be displayed in the window.

  Here, FIG. 13 shows a screen display state of the screen display device 6a when the user performs a mouse operation. An electrocardiogram extended display window 130 is displayed on the share window 100. Here, an example in which a mouse operation is performed on the electrocardiogram examination image 101g of the reference candidate 7: 2009/02/02 is displayed. The electrocardiogram extended display window 130 can browse a plurality of ECG examination images in a list. In addition, it is possible to filter the image to be displayed in the observation information and subject behavior information selection area 130a by the finding information and the subject behavior information given to the image, and one or a plurality of the findings information and the subject. It is possible to specify the action information. By filtering the electrocardiogram image to be displayed by designating and displaying a plurality of observation information and behavior information of the subject, for example, the behavior information “prone position” of the subject and the finding information “ST rise” are displayed on one ECG image. When information is given, the state of the electrocardiogram waveform in a specific state of the subject can be easily understood.

  According to the present invention, when displaying a reference image or a reference examination and examination information as a comparison candidate together, it is possible to display a heartbeat that is highly interested by the user for the electrocardiogram waveform. Thereby, comparative interpretation and reference are easy for the user.

  When the subject is an arrhythmia or the like, the ECG waveform data for one day is often measured. In order to compare a past electrocardiogram waveform for comparison with a reference image or a reference examination, conventionally, the user himself / herself has to search for heartbeats of high interest from one-day ECG waveform data. In the present invention, a partial image of an electrocardiogram waveform near the time to which finding information and behavior information are given is generated and the partial image is automatically displayed, so that the user's work efficiency is dramatically increased.

  Furthermore, an electrocardiogram waveform near the examination time of the examination image of the comparison candidate can be displayed as a comparison candidate. Thereby, an electrocardiogram examination and the test | inspection image implemented at the same time can be shown to a user simultaneously.

  Furthermore, at the time of creating the partial image of the electrocardiogram waveform, the display order of the image display is assigned to the type of the observation information or the behavior information of the subject, so that the image display order is the image that is of high interest to the user in order. It becomes easy to display. In addition, by filtering the findings information or the type of subject behavior information and displaying a list of electrocardiogram images, it becomes easy to list and view information that is of high interest to the user.

  Furthermore, by filtering the partial images of the electrocardiogram waveforms to be displayed in a list according to a plurality of types of finding information and action information, the state of the electrocardiogram waveform in a specific state of the subject can be easily understood.
