At the present stage, different electrocardiogram waveform data are generally collected, corresponding different electrocardiogram waveforms are directly drawn in an overlapping mode, the different electrocardiogram waveforms drawn in the overlapping mode are displayed, and the different electrocardiogram waveforms can be conveniently contrasted and analyzed in the overlapping drawing and displaying mode; is helpful for doctors to carry out relevant scientific research and analysis on heart diseases. However, the inventor finds that the acquisition nodes of the different electrocardiographic waveform data are likely to be located at different nodes of the cardiac cycle, and the corresponding different electrocardiographic waveforms are directly drawn in an overlapping manner based on the different electrocardiographic waveform data, so that the comparison of the different electrocardiographic waveforms is not accurate and meaningless, and the comparison analysis of the different electrocardiographic waveforms is not referential.
To solve this problem, in the embodiment of the present application, each piece of electrocardiographic waveform data in the electrocardiographic waveform comparison list is acquired, and the start of the first complete cardiac cycle of each piece of electrocardiographic waveform data is determined; for each electrocardiogram waveform data, overlapping and drawing each corresponding electrocardiogram waveform by taking the starting point of the first complete cardiac cycle of each electrocardiogram waveform data as the drawing starting point; wherein, the line formats of any two electrocardiogram waveforms are different; and displaying the superposed electrocardiogram waveforms. Therefore, by means of calculating the starting point of the first complete cardiac cycle of the electrocardiogram waveform data, each electrocardiogram waveform is ensured to be drawn in an overlapping mode by taking the starting point of the first complete cardiac cycle of the corresponding electrocardiogram waveform data as the drawing starting point, so that the comparison of each electrocardiogram waveform is more accurate and meaningful, and the comparison and analysis of each electrocardiogram waveform has referential property.
For example, one of the scenarios of the embodiment of the present application may be applied to the scenario shown in fig. 1, which includes the electrocardiograph 101, the processor 102 and the display 103, wherein the electrocardiograph 101 interacts with the processor 102, and the processor 102 interacts with the display 103. The processor 102 obtains the electrocardiograph waveform data from the electrocardiograph 101, and displays the electrocardiograph waveforms after the overlapping rendering through the display 103 according to the embodiment provided by the embodiment of the present application.
First, in the application scenario described above, although the actions of the embodiments provided in the embodiments of the present application are described as being performed by the processor 102; however, the embodiments of the present application are not limited in terms of executing subjects as long as the actions disclosed in the embodiments provided by the embodiments of the present application are executed.
Next, the above scenario is only one example of the scenario provided in the embodiment of the present application, and the embodiment of the present application is not limited to this scenario.
The following describes in detail a specific implementation manner of a method for displaying an electrocardiogram waveform and a related apparatus according to an embodiment of the present application, with reference to the accompanying drawings.
Exemplary method
Referring to fig. 2, a flow chart of a method for displaying an electrocardiogram waveform in an embodiment of the present application is shown. In this embodiment, the method may include, for example, the steps of:
step 201: and determining the starting point of the first complete cardiac cycle of each electrocardiogram waveform data based on each electrocardiogram waveform data in the electrocardiogram waveform comparison list.
In the embodiment of the present application, an electrocardiogram waveform contrast list is preset, and the electrocardiogram waveform data to be contrasted and analyzed are stored in the electrocardiogram waveform contrast list. If so, directly drawing each electrocardiogram waveform corresponding to each electrocardiogram waveform data in the electrocardiogram waveform comparison list in an overlapping manner, and displaying each electrocardiogram waveform after the overlapping drawing; the method does not consider that the acquisition nodes of the electrocardiogram waveform data are likely to be at different nodes of the cardiac cycle, and has the problems that the comparison of the electrocardiogram waveforms is not accurate and meaningless, so that the comparative analysis of the electrocardiogram waveforms does not have referential property. In order to solve the above problem, attention needs to be paid to the first complete cardiac cycle of each electrocardiogram waveform data in the electrocardiogram waveform comparison list to determine the starting point of the first complete cardiac cycle of each electrocardiogram waveform data. Wherein a cardiac cycle refers to the process that the cardiovascular system undergoes from the start of one heartbeat to the start of the next heartbeat.
In the embodiment of the present application, because the electrocardiogram waveform data to be contrasted and analyzed stored in the electrocardiogram waveform contrast list is mainly used for helping doctors to analyze the pathological changes of the same heart disease patients, or scientific research analysis of the features of the same heart disease, and the like. Therefore, the past electrocardiogram waveform data of the same heart disease patient can be screened through a preset screening condition and stored in an electrocardiogram waveform comparison list; the electrocardiogram waveform data of different heart disease patients in the same heart disease patients can be screened through another preset screening condition and stored in the electrocardiogram waveform comparison list. The preset screening condition can be preset by various combinations of patient name, patient gender, patient age, patient region and diagnosis characteristics. That is, in an alternative implementation manner of the embodiment of the present application, each piece of electrocardiographic waveform data in the electrocardiographic waveform comparison list refers to electrocardiographic waveform data of a previous time of the same heart disease patient or electrocardiographic waveform data of different heart disease patients in the same heart disease patient, which are obtained by screening according to a preset screening condition; the preset screening conditions comprise a plurality of patient names, patient sexes, patient ages, areas where the patients are located and diagnosis characteristics.
In the embodiment of the application, a uniform processing mode is adopted for subsequent processing of the electrocardiogram waveform data in the electrocardiogram waveform comparison list; for electrocardiogram waveform data, a unified data storage standard structure format is preset as a preset data storage format, and each electrocardiogram waveform data to be contrasted and analyzed is stored in the electrocardiogram waveform contrast list by adopting the preset data storage format. Therefore, in an optional implementation manner of the embodiment of the present application, each electrocardiographic waveform data in the electrocardiographic waveform comparison list adopts a preset data storage format.
In the embodiment of the application, the cardiac cycle of the electrocardiogram waveform data is related to the electrocardiogram waveform data center electrical connection data; therefore, when step 201 is implemented, first, the electrocardiographic lead data in each electrocardiographic waveform data needs to be read from each electrocardiographic waveform data in the electrocardiographic waveform comparison list; then, on the basis of the electrocardiogram lead data in each electrocardiogram waveform data, the starting point of the first complete cardiac cycle of each electrocardiogram waveform data is obtained through calculation and analysis. That is, in an optional implementation manner of the embodiment of the present application, the step 201 may include, for example, the following steps:
step A: reading electrocardiogram lead data in the electrocardiogram waveform data based on the electrocardiogram waveform data in the electrocardiogram waveform comparison list;
and B: and calculating the starting point of the first complete cardiac cycle of each electrocardiogram waveform data based on the electrocardiogram lead data in each electrocardiogram waveform data.
Step 202: based on each electrocardiogram waveform data, overlapping and drawing each corresponding electrocardiogram waveform by taking the starting point of the first complete cardiac cycle of each electrocardiogram waveform data as a drawing starting point; the line formats of any two of the electrocardiogram waveforms are different.
In the embodiment of the present application, after the step 201 is executed to determine the start point of the first complete cardiac cycle of each piece of electrocardiographic waveform data in the electrocardiographic waveform comparison list, it is necessary to draw each corresponding electrocardiographic waveform in an overlapping manner by taking the start point of the first complete cardiac cycle of each piece of electrocardiographic waveform data as a drawing start point for each piece of electrocardiographic waveform data no matter at which node of the cardiac cycle each piece of electrocardiographic waveform data in the electrocardiographic waveform comparison list is located. Namely, each electrocardiogram waveform is drawn in an overlapping manner from the starting point of the first complete cardiac cycle of the electrocardiogram waveform data corresponding to each electrocardiogram waveform, so that the comparison of each electrocardiogram waveform can be more accurate and meaningful, and the comparison and analysis of each electrocardiogram waveform have referential property.
In the embodiment of the present application, in order to distinguish between the electrocardiographic waveforms and avoid confusion and error of the electrocardiographic waveforms, different electrocardiographic waveforms need to adopt different line formats, that is, on the basis of the electrocardiographic waveform data, in the process of overlapping and drawing the corresponding electrocardiographic waveforms, the line formats of any two electrocardiographic waveforms are different. The different line formats for easily distinguishing the electrocardiogram waveforms can be different line colors, different line types and different combinations of the line colors and the line types. Therefore, in an optional implementation manner of the embodiment of the present application, the line format includes a line color and/or a line type.
As an example, the line format is line color, assuming that the line colors of the 4 electrocardiogram waveforms are blue, orange, red, green, respectively; as another example, the line format is a line type, and it is assumed that the line types of the 4 electrocardiogram waveforms are a solid line type, a first broken line type, a second broken line type, and a third broken line type, respectively. As yet another example, the line formats are line color and line type, assuming that the line colors and line types of the 4 electrocardiogram waveforms are: blue + solid line type, orange + first dotted line type, red + second dotted line type, green + third dotted line type. The first dotted line type, the second dotted line type and the third dotted line type are different.
Step 203: and displaying each electrocardiogram waveform after overlapping and drawing.
In the embodiment of the present application, after the step 202 is executed to complete the overlapping rendering of the electrocardiographic waveforms, the respective electrocardiographic waveforms after the overlapping rendering need to be displayed to a user, such as a doctor; so as to facilitate the physician's scientific analysis of heart diseases, for example, as shown in fig. 3, a schematic diagram of the display of the overlapped electrocardiographic waveforms. Because each electrocardiogram waveform after the overlapping drawing takes the starting point of the first complete cardiac cycle of the corresponding electrocardiogram waveform data as the drawing starting point, when a user performs contrastive analysis according to each displayed electrocardiogram waveform after the overlapping drawing, the contrast of each electrocardiogram waveform is more accurate and meaningful, thereby the contrastive analysis of each electrocardiogram waveform has referential property.
Correspondingly, by the implementation of steps 201 to 203, when each piece of electrocardiogram waveform data in the electrocardiogram waveform comparison list refers to the past electrocardiogram waveform data of the same heart disease patient obtained by screening according to the preset screening condition, the lesion trend analysis of the same heart disease patient can be more accurate and have the referential property; when each electrocardiogram waveform data in the electrocardiogram waveform comparison list refers to electrocardiogram waveform data of different heart disease patients in the same heart disease patient obtained by screening according to the preset screening condition, the scientific research and analysis of the characteristics of the same heart disease can be more accurate and have reference.
In the embodiment, in addition to the electrocardiographic waveform data, twelve leads are generally drawn by default for each electrocardiographic waveform in the overlapping drawing of the corresponding electrocardiographic waveforms, and the twelve leads are also generally displayed by default for each electrocardiographic waveform when the electrocardiographic waveforms after the overlapping drawing are displayed.
On the basis of the above description, in order to facilitate the user to carefully analyze the leads in the electrocardiogram waveform, for example, considering that the user is a doctor with a large age and poor eyesight, an amplification operation is set for the leads to amplify the leads in the electrocardiogram waveform. In addition, the user can conveniently observe and analyze the leads in the electrocardiogram waveform from different angles, and not only can amplify a single lead in the electrocardiogram waveform, but also can amplify a plurality of leads in the electrocardiogram waveform. Specifically, in the first mode, through the amplification operation of a user on a single lead, correspondingly, the single lead in each electrocardiographic waveform after the overlapping drawing is synchronously amplified and displayed; in the second method, a user performs an operation of enlarging a plurality of leads to synchronously enlarge and display the plurality of leads in each of the electrocardiographic waveforms after the superimposition drawing.
That is, in an alternative implementation manner of this embodiment of the present application, the electrocardiogram waveform includes twelve leads, and after the step 203, for example, the method may further include a step C: synchronously amplifying and displaying the single leads in each electrocardiogram waveform after the overlapped drawing in response to the operation of amplifying the single leads by a user; or, step D: and synchronously amplifying and displaying the plurality of leads in each electrocardiogram waveform after the overlapped drawing in response to the operation of amplifying the plurality of leads by the user.
It should be further noted that, in the embodiment of the present application, in order to facilitate the subsequent user to check each electrocardiographic waveform after the overlapping drawing, and to facilitate understanding of the screening condition, the unique identifier, and the like of each electrocardiographic waveform data corresponding to the electrocardiographic waveform; the screening conditions, the unique identifiers of the electrocardiogram waveform data and the electrocardiogram waveforms after overlapping drawing can be correspondingly stored to form an electrocardiogram waveform contrast scheme. Therefore, in an optional implementation manner of this embodiment of the present application, after the step 203, for example, a step E may further be included: and correspondingly storing the preset screening conditions, the unique identification of each electrocardiogram waveform data and each electrocardiogram waveform after overlapping drawing.
Through various implementation manners provided by the embodiment, firstly, each electrocardiogram waveform data in the electrocardiogram waveform comparison list is obtained, and the starting point of the first complete cardiac cycle of each electrocardiogram waveform data is determined; then, regarding each electrocardiogram waveform data, overlapping and drawing each corresponding electrocardiogram waveform by taking the starting point of the first complete cardiac cycle of each electrocardiogram waveform data as the drawing starting point; wherein, the line formats of any two electrocardiogram waveforms are different; finally, the electrocardiographic waveforms after the overlapping rendering are displayed. Therefore, by means of calculating the starting point of the first complete cardiac cycle of the electrocardiogram waveform data, each electrocardiogram waveform is ensured to be drawn in an overlapping mode by taking the starting point of the first complete cardiac cycle of the corresponding electrocardiogram waveform data as the drawing starting point, so that the comparison of each electrocardiogram waveform is more accurate and meaningful, and the comparison and analysis of each electrocardiogram waveform has referential property.
