[0040] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for displaying an ECG signal in an embodiment of the present application. It should be noted that if there are substantially the same results, the method of the present application is not limited to the method of displaying an ECG signal in an embodiment of the present application. Figure 1The process sequence shown is limited. This method can be applied to an electrocardiograph 200 having functions such as calculation, etc., see Figure 2 , Figure 2 2 is a schematic diagram of the structure of an electrocardiograph in an embodiment of the present application. The electrocardiograph 200 includes a memory 201, a processor 202 and a display 203 which are coupled to each other. The processor 202 is used to execute program instructions stored in the memory 201 to implement the steps in the embodiment of the method for displaying electrocardiogram signals. The display 203 is used to display the results obtained by the processor 202 executing the program instructions.

[0041] Specifically, the processor 202 is used to control itself and the memory 201 to implement the steps in the embodiment of the above-mentioned method for displaying the electrocardiogram signal. The processor 202 can also be called a CPU (Central Processing Unit), and the processor 202 may be an integrated circuit chip with signal processing capabilities.

The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc. In addition, the processor 202 can be implemented by an integrated circuit chip.

[0042] The electrocardiograph 200 may execute the method by receiving relevant information. Figure 1 As shown, the method for displaying an electrocardiogram signal comprises the following steps:

[0043] S1. Acquire an ECG waveform signal, where the ECG waveform signal includes ECG waveform signals of leads X, Y, and Z.

[0044] The ECG waveform signal is obtained, and the ECG waveform signal is used to represent the ECG waveform data of the human body, wherein the ECG waveform signal includes the ECG waveform signal of the X lead, the ECG waveform signal of the Y lead, and the ECG waveform signal of the Z lead.

[0045] S2. Obtain a corresponding time domain graph and / or frequency domain graph based on the ECG waveform signal, wherein the time domain graph and the frequency domain graph are used to analyze ventricular late potentials of the ECG waveform signal.

[0046] Based on the ECG waveform signal, the corresponding time domain graph and frequency domain graph can be obtained, and the time domain graph and frequency domain graph are used to analyze the ventricular late potential of the ECG waveform signal.

[0047] S3. Display a time domain graph and / or a frequency domain graph.

[0048] The obtained time domain graph and frequency domain graph are displayed, wherein the time domain graph and the frequency domain graph can be displayed separately or simultaneously, so as to intuitively display the time domain graph and the frequency domain graph for easy viewing.

[0049] The above scheme obtains an ECG waveform signal, which includes ECG waveform signals of X, Y and Z leads; obtains a corresponding time domain graph and / or frequency domain graph based on the ECG waveform signal, and the time domain graph and frequency domain graph are used to analyze the ventricular late potential of the ECG waveform signal; and displays the time domain graph and / or frequency domain graph; the scheme in the present application obtains a corresponding time domain graph and / or frequency domain graph based on the ECG waveform signal, which is used to analyze the ventricular late potential, and displays the time domain graph and / or frequency domain graph, which is convenient for doctors to view and effectively improves work efficiency.

[0050] In one embodiment of the present application, the electrocardiogram waveform signals of the X, Y and Z leads are obtained through an orthogonal lead system.

[0051] Understandably, Figure 3 is a schematic diagram showing the display of an ECG waveform signal in an embodiment of the present application, such as Figure 3 As shown, the orthogonal lead system includes a standard Frank lead system or a bipolar orthogonal system, which connects each lead to the corresponding position of the human body and uses electrodes on the human body surface to collect the ECG waveform signals of the human body's X, Y, and Z leads. Based on the ECG waveform signal, the corresponding time domain and frequency domain diagrams can be obtained, and then the ventricular late potential can be analyzed.

[0052] In one embodiment of the present application, obtaining a corresponding time domain diagram and / or frequency domain diagram based on an ECG waveform signal includes: amplifying the ECG waveform signal to obtain an amplified ECG waveform signal; superimposing and averaging a preset number of beats in the ECG waveform signal of each lead in the amplified ECG waveform signal to obtain standard unfiltered signals of leads X, Y, and Z; performing root mean square processing on each corresponding point of the standard unfiltered signals of leads X, Y, and Z to obtain a comprehensive QRS wave; filtering the comprehensive QRS wave to obtain a filtered comprehensive QRS wave; and obtaining a time domain diagram based on the filtered comprehensive QRS wave and / or the standard unfiltered signals of leads X, Y, and Z.

[0053] It is understandable that the ECG waveform signal is amplified to obtain an amplified ECG waveform signal. Specifically, the ECG waveform signal is amplified, that is, the ECG waveform signal is processed by a high-gain amplifier to amplify the details of the ECG waveform signal, or other achievable amplification processing methods are all possible, which can be selected according to actual use requirements without specific limitation. The preset number of heart beats in the ECG waveform signal of each lead in the amplified ECG waveform signal are superimposed and averaged to obtain standard unfiltered signals of the X, Y and Z leads. For example, for the X-lead ECG waveform signal in the amplified ECG waveform signal, a preset number of heart beats are first superimposed and then averaged to obtain a standard unfiltered signal of the X-lead; for the Y-lead ECG waveform signal in the amplified ECG waveform signal, a preset number of heart beats are first superimposed and then averaged to obtain a standard unfiltered signal of the Y-lead; for the Z-lead ECG waveform signal in the amplified ECG waveform signal, a preset number of heart beats are first superimposed and then averaged to obtain a standard unfiltered signal of the Z-lead. Each corresponding point in the standard unfiltered signals of the X, Y and Z leads is subjected to root mean square processing to obtain a comprehensive QRS wave. The comprehensive QRS wave is filtered to obtain a filtered comprehensive QRS wave, that is, the comprehensive QRS wave is filtered by a filter to filter out unnecessary signals; the filter can be a high-frequency filter, such as a high-frequency filter with a frequency of 25-250Hz or 40-250Hz, or other achievable filters, which can be selected according to actual use requirements without specific limitation. Furthermore, a time domain diagram is obtained based on the filtered integrated QRS complex and / or the standard unfiltered signals of the X, Y and Z leads, and the obtained time domain diagram is displayed.

[0054] In one embodiment of the present application, a time domain graph and / or a frequency domain graph is displayed, including: obtaining a first analysis parameter of a ventricular late potential and a value thereof, wherein the first analysis parameter and a value thereof are measured on a filtered integrated QRS wave and / or a standard unfiltered signal of the X, Y and Z leads; and displaying the first analysis parameter and a value thereof in a preset manner, wherein the first analysis parameter and a value thereof are displayed simultaneously with the time domain graph.

[0055] The first analysis parameter of the ventricular late potential and its value are obtained by measuring the filtered integrated QRS wave and / or the standard unfiltered signals of the X, Y and Z leads. It can be understood that the corresponding first analysis parameter and the specific value of the first analysis parameter can be obtained by measuring the filtered integrated QRS wave and / or the standard unfiltered signals of the X, Y and Z leads. The first analysis parameter can include multiple parameters, such as heart rate, noise, or other parameters that can be analyzed, without specific limitation.

[0056] Figure 4 is a schematic diagram of the first scene displayed on the interface in the embodiment of the present application, Figure 5 is a schematic diagram of the display of the analysis parameter display box in the embodiment of the present application, such as Figure 4 and Figure 5 As shown, the first analysis parameter and its value are displayed in a preset manner. It can be understood that the measured first analysis parameter and its value can be explicitly displayed in a preset manner. For example, the first analysis parameter and its value are controlled to be explicitly displayed in the first analysis parameter display box W15 in the manner of the preset list M1. The first analysis parameter and its value can be controlled to be explicitly displayed in two parameter columns, and each parameter row displays a first analysis parameter and its value. For example, the first analysis parameter displayed in the first parameter column of the first parameter row D1 is noise, and the second parameter column of the first parameter row D1 corresponds to the value of the first analysis parameter, that is, the value of noise; the first analysis parameter displayed in the first parameter column of the second parameter row D2 is the heart rate, and the second parameter column of the second parameter row D2 corresponds to the value of the first analysis parameter, that is, the value of the heart rate.

[0057] In some embodiments, when the number of first analysis parameters and their values ​​is large and it is impossible to display all of the first analysis parameters and their values ​​at the same time, a preset number of first analysis parameters and their values ​​in the preset list M1 can be controlled to be displayed explicitly, and other first analysis parameters and their values ​​in the preset list M1 can be controlled to be displayed implicitly. In response to an instruction to trigger the explicit display of the first analysis parameters and their values ​​in the implicitly displayed parameter row, the first analysis parameters and their values ​​in the corresponding implicitly displayed parameter row are controlled to be displayed explicitly, and the first analysis parameters and their values ​​in the same number of explicitly displayed parameter rows are controlled to be displayed implicitly, that is, the parameter rows that are explicitly displayed in the preset list M1 can be changed, but the total number of parameter rows that are explicitly displayed remains at the preset number.

[0058] Please refer again Figure 5 , taking the display 203 having a touch screen interactive function as an example, the interface W1 of the medical software is displayed and presented through the display 203. All the first analysis parameters and their values ​​are arranged according to the preset list M1, and the first analysis parameter display box W15 includes a preset progress bar W151, and the preset progress bar W151 can be located on one side of the first analysis parameter display box W15. The preset progress bar W151 includes a preset icon W1511, and the position of the preset icon W1511 in the preset progress bar W151 can correspond to the position of the parameter row in the preset list M1, that is, when the position of the preset icon W1511 is changed, the position of the corresponding parameter row is also changed.

[0059] Control a preset number of first analysis parameters and their values ​​to be displayed explicitly, and the position of the preset icon W1511 corresponds to the number of parameter rows of the first analysis parameters and their values ​​that are displayed explicitly. The instruction to trigger the explicit display of the first analysis parameter and its value in the implicit display parameter row can be triggered by clicking the position of the preset icon W1511 with the mouse, or by touching the position of the preset icon W1511 on the display 203, or other triggering methods that can be implemented are all possible, without specific limitation. For example, touch the position of the preset icon W1511 on the display 203, and long press and drag the preset icon W1511, so as to control the explicit display of the first analysis parameter and its value in the corresponding implicit display parameter row. When the position of the preset icon W1511 in the preset progress bar W151 changes, the corresponding parameter row in the preset list M1 is controlled to scroll and display explicitly, so as to realize the explicit display of the first analysis parameter and its value in the corresponding parameter row by dragging the preset icon W1511, so as to control the explicit display of the corresponding first analysis parameter and its value according to the actual viewing needs, so as to facilitate viewing.

[0060] For example, the number of first analysis parameters is ten, and the number of corresponding first analysis parameter values ​​is also ten. The list M1 consisting of twenty first analysis parameters and their values ​​includes 10 parameter rows D1-D10 and 2 parameter columns. The first analysis parameter display box W15 can display 6 parameter rows explicitly at the same time. The first analysis parameter display box W15 initially explicitly displays the 1st to 6th parameter rows D1-D6 in the list M1, and the 7th to 10th parameter rows D7-D10 are implicitly displayed. Drag the preset icon W1511 to make the first analysis parameter and its value of the corresponding parameter row displayed explicitly. If the preset progress bar W151 is set in the vertical direction, drag the preset icon W1511 downward, then the first analysis parameter display box W15 will explicitly display the 3rd parameter row to the 8th parameter row D3-D8, as shown in the solid line portion of the parameter row in the figure, and at the same time, the 1st parameter row to the 2nd parameter row D1-D2, and the 9th parameter row to the 10th parameter row D9-D10 will be implicitly displayed, as shown in the dotted line portion of the parameter row in the figure; continue to drag the preset icon W1511 downward, then the first analysis parameter display box W15 will explicitly display the 5th parameter row to the 10th parameter row D5-D10, and at the same time, the 1st parameter row to the 4th parameter row D1-D4 will be implicitly displayed, thereby realizing the selection of the first analysis parameter and its value for explicit display according to actual needs.

[0061] The first analysis parameter and its value are displayed together with the time domain diagram W11. Please refer to it again for understanding. Figure 4 The first analysis parameter and its value are displayed in the first analysis parameter display box W15. The first analysis parameter display box W15 and the time domain graph W11 are simultaneously displayed on the interface W1 of the medical software, so as to facilitate simultaneous comparison and viewing.

[0062] In one embodiment of the present application, the method for displaying an ECG signal further includes: acquiring and displaying filtering parameters of a filtering process, and a schematic diagram of filtering a comprehensive QRS wave using the filtering parameters of the filtering process, wherein the schematic diagram is displayed simultaneously with the comprehensive QRS wave. In response to an instruction to trigger the display of the filtering parameters, alternative filtering parameters of the filtering process are acquired and displayed, so that when the alternative filtering parameters are selected, a schematic diagram of filtering the comprehensive QRS wave using the alternative filtering parameters is displayed.

[0063] The filtering parameters of the filtering process are obtained, and a schematic diagram of filtering the integrated QRS wave using the filtering parameters of the filtering process, wherein the schematic diagram is displayed simultaneously with the integrated QRS wave. It can be understood that the filtering parameters of the filtering process are obtained, and the filtering parameters are controlled to be displayed on the interface W1 of the medical software, and the corresponding integrated QRS wave is filtered using the filtering parameters to obtain a schematic diagram of the filtering of the integrated QRS wave, and the schematic diagram and the corresponding integrated QRS wave are controlled to be displayed simultaneously on the interface W1 of the medical software.

[0064] In response to the instruction of the filter parameter that triggers the display, the alternative filter parameter for the filtering process is obtained and displayed, so that when the alternative filter parameter is selected, a schematic diagram of the alternative filter parameter filtering the integrated QRS wave is displayed. It can be understood that the number of filter parameters can be multiple, and then there is at least one alternative filter parameter. According to actual use requirements, a suitable alternative filter parameter can be selected to filter the integrated QRS wave to obtain a corresponding filtering schematic diagram.

[0065] Figure 6 is a schematic diagram showing a filter parameter selection box in an embodiment of the present application. Figure 6 As shown, for example, a filter parameter selection box W16 is displayed on the interface W1 of the medical software, and the filter parameters are displayed in the preset parameter list M2. The filter parameter selection box W16 explicitly displays the currently selected filter parameters, and the remaining candidate filter parameters are implicitly displayed. An instruction to trigger the filter parameters displayed on the interface W1 of the medical software is received, that is, all the filter parameters in the preset parameter list M2 are controlled to be explicitly displayed, and an instruction to trigger the filter parameters displayed on the filter parameter selection box W16 is received, and the instruction is used to trigger the filter parameters in the preset parameter list M2 to be selected.

[0066] Taking the display 203 having a touch screen interactive function as an example, the interface W1 of the medical software is displayed through the display 203. The interface W1 of the medical software includes a filter parameter selection box W16. The location of the filter parameter selection box W16 can be clicked by the mouse, or the location of the filter parameter selection box W16 can be touched to trigger the explicit display of all the filter parameters in the preset parameter list M2. The instruction to trigger the filter parameters displayed on the interface of the medical software can be triggered by clicking the location of the filter parameters with the mouse, or by touching the location of the filter parameters displayed on the display 203, or other triggering methods that can be realized are all OK, without specific limitation.

[0067] For example, in response to clicking the location of the filter parameter on the touch display 203 to trigger an instruction, the integrated QRS wave is filtered using the selected alternative filter parameter to obtain a corresponding filter schematic diagram, and the integrated QRS wave and the corresponding filter schematic diagram are controlled to be displayed at the same time, the selected alternative filter parameter is controlled to be explicitly displayed on the filter parameter selection box W16, and the remaining filter parameters are controlled to be implicitly displayed.

[0068] In one embodiment of the present application, displaying a time domain diagram and / or a frequency domain diagram also includes: displaying a first starting point marking line and a first end point marking line on the standard unfiltered signal of the currently displayed X, Y or Z lead, the first starting point marking line and the first end point marking line are used to calculate the standard QRS wave duration; displaying a second starting point marking line and a second end point marking line on the filtered integrated QRS wave, the second starting point marking line and the second end point marking line are used to calculate the total QRS wave duration, the QRS wave terminal time and the QRS wave terminal amplitude parameters.

[0069] FIG7(a) is a schematic diagram of the first scenario of the time domain diagram in the embodiment of the present application, FIG7(b) is a schematic diagram of the second scenario of the time domain diagram in the embodiment of the present application, and FIG7(c) is a schematic diagram of the third scenario of the time domain diagram in the embodiment of the present application. Figure 7(a) to Figure 7(c) As shown, the time domain diagram W11 includes standard unfiltered signals (W111, W112, W113) of the X, Y and Z leads, and also includes a filtered integrated QRS wave W114. Among them, the standard unfiltered signal W111 of the X lead, the standard unfiltered signal W112 of the Y lead and the standard unfiltered signal W113 of the Z lead are displayed separately, and the currently displayed standard unfiltered signal W111 of the X lead, the standard unfiltered signal W112 of the Y lead or the standard unfiltered signal W113 of the Z lead are displayed in parallel with the filtered integrated QRS wave W114.

[0070] The time domain graph W11 also includes a preset first selection bar W117, which corresponds to the currently displayed standard unfiltered signal W111 of lead X, standard unfiltered signal W112 of lead Y, or standard unfiltered signal W113 of lead Z. Changing the position of the preset first selection bar W117 is used to trigger an instruction to explicitly display the implicitly displayed standard unfiltered signal of the lead and the filtered integrated QRS wave, thereby explicitly displaying the standard unfiltered signal of the corresponding lead and the filtered integrated QRS wave.

[0071] Taking the display 203 having a touch screen interactive function as an example, the interface W1 of the medical software is displayed through the display 203, and the interface W1 of the medical software includes a time domain diagram W11. Please refer to Figure 7 (a) again. The time domain diagram W11 initially and simultaneously displays the relevant information of the standard unfiltered signal W111 of the X lead and the filtered integrated QRS wave W114, and the standard unfiltered signals of the other leads are displayed implicitly, and the preset first selection bar W117 is set in the vertical direction.

[0072] The instruction for triggering the explicit display of the standard unfiltered signal of the implicitly displayed lead can be triggered by clicking the location of the preset first selection bar W117 with a mouse, or by touching the location of the preset first selection bar W117 on the display 203, or by other triggering methods that can be implemented, without specific limitation. For example, the location of the preset first selection bar W117 on the touch display 203, and long press and drag the preset first selection bar W117, thereby controlling the explicit display of the standard unfiltered signal of the corresponding implicitly displayed lead.

[0073] Please refer to Figure 7(b) again. In response to the trigger instruction of dragging the preset first selection bar W117 downward, the standard unfiltered signal W112 of the Y lead and the filtered integrated QRS wave W114 are controlled to be displayed explicitly, and the relevant information of the standard unfiltered signal W112 of the Y lead and the filtered integrated QRS wave W114 is displayed explicitly, and the standard unfiltered signals of the remaining leads are controlled to be displayed implicitly.

[0074] Please refer to FIG. 7( c ) again. In response to the trigger instruction of dragging the preset first selection bar W117 downward, the standard unfiltered signal W113 of the Z lead and the filtered integrated QRS wave W114 are controlled to be displayed explicitly, and the relevant information of the standard unfiltered signal W113 of the Z lead and the filtered integrated QRS wave W114 are displayed explicitly, and the standard unfiltered signals of the remaining leads are controlled to be displayed implicitly, so that the standard unfiltered signal of the corresponding lead can be selected for explicit display as needed. In addition, dragging the preset first selection bar W117 upward can also trigger the instruction, thereby controlling the standard unfiltered signal of the corresponding lead and the filtered integrated QRS wave W114 to be displayed explicitly.

[0075] Please refer again Figure 4 , Figure 7(a) to Figure 7(c) It can be understood that the first starting point mark line F1 and the first end point mark line F2 are displayed on the standard unfiltered signal of the currently displayed X, Y or Z lead, and the first starting point mark line F1 and the second starting point mark line F2 are used to calculate the standard QRS wave time limit. Among them, the standard QRS wave time limit is the QRS interval measured on the standard unfiltered signal; for example, the QRS interval measured on the standard unfiltered signal W111 of the X lead is the standard QRS wave time limit of the X lead, the QRS interval measured on the standard unfiltered signal W112 of the Y lead is the standard QRS wave time limit of the Y lead, and the QRS interval measured on the standard unfiltered signal W113 of the Z lead is the standard QRS wave time limit of the Z lead.

[0076] Please refer again Figure 4 , Figure 7(a) to Figure 7(c) The second starting point marking line F3 and the second end point marking line F4 are displayed on the filtered comprehensive QRS wave. The second starting point marking line F3 and the second end point marking line F4 are used to calculate the total QRS wave duration, the QRS wave terminal time and the QRS wave terminal amplitude parameters.

[0077] Specifically, according to the filtered integrated QRS wave, the total QRS wave time limit, QRS wave terminal time and QRS wave terminal amplitude parameter are calculated. Among them, the total QRS wave time limit is the QRS interval measured on the filtered integrated QRS wave; the QRS wave terminal time refers to the duration of the amplitude at the end of the filtered integrated QRS wave lower than 40μV, that is, the duration of the 40μV low-amplitude high-frequency fragmented electric wave; the QRS wave terminal amplitude parameter refers to the root mean square value of the amplitude within 40ms at the end of the filtered integrated QRS wave, that is, the amplitude value at the end of the filtered synthetic QRS wave with an amplitude lower than 40μV is calculated by the root mean square calculation, so as to obtain the QRS wave terminal amplitude parameter.

[0078] In one embodiment of the present application, the method for displaying an electrocardiogram signal also includes: in response to a movement operation on either the first starting point marking line or the first ending point marking line, obtaining an updated value of the standard QRS wave duration, and updating and displaying it; and / or, in response to a movement operation on either the second starting point marking line or the second ending point marking line, obtaining an updated value of the total QRS wave duration, QRS wave terminal time, and QRS wave terminal amplitude parameters, and updating and displaying them.

[0079] The first starting point marking line F1 and the first end point marking line F2 are used to calculate the standard QRS wave duration. When the first starting point marking line F1 or the first end point marking line F2 is moved, it is understandable that the corresponding QRS interval will change. In response to the moving operation of any one of the first starting point marking line F1 and the first end point marking line F2, the updated value of the standard QRS wave duration is obtained, that is, the standard QRS wave duration is recalculated according to the moved first starting point marking line F1 and the first end point marking line F2 to obtain the updated value of the standard QRS wave duration, and the updated value is updated and displayed, such as updating the updated value of the standard QRS wave duration and displaying it in the first analysis parameter display box W15.

[0080] The second starting point mark line F3 and the second end point mark line F4 are displayed on each filtered integrated QRS wave. According to the filtered integrated QRS wave, the total QRS wave time limit, the QRS wave end time and the QRS wave end amplitude parameters can be calculated. When any one of the second starting point mark line F3 or the second end point mark line F4 is moved, it can be understood that the QRS interval of the corresponding filtered integrated QRS wave will change, thereby causing the QRS interval of the filtered integrated QRS wave to change. In response to the moving operation of any one of the second starting point mark line F3 and the second end point mark line F4, the updated values ​​of the total QRS wave time limit, the QRS wave end time and the QRS wave end amplitude parameters are obtained, that is, the updated values ​​of the total QRS wave time limit, the QRS wave end time and the QRS wave end amplitude parameters of the corresponding filtered integrated QRS wave are calculated according to the moved second starting point mark line F3 and the second end point mark line F4. The updated values ​​are updated and displayed, such as the updated values ​​of the total QRS wave duration, the QRS wave terminal time and the QRS wave terminal amplitude parameters are updated and displayed in the first analysis parameter display box W15.

[0081] In one embodiment of the present application, the waveform position of the ventricular late potential is marked on the filtered integrated QRS wave in a preset marking manner.

[0082] Please refer again Figure 4 The waveform position of the ventricular late potential is marked on the filtered integrated QRS wave in a preset marking manner. For example, the waveform position of the ventricular late potential can be displayed in bold, the color of the waveform position of the ventricular late potential can be changed, the waveform position of the ventricular late potential can be filled and displayed, or other achievable methods of marking the waveform position of the ventricular late potential are all possible, without specific limitation.

[0083] In one embodiment of the present application, obtaining a corresponding time domain diagram and / or frequency domain diagram based on an ECG waveform signal also includes: amplifying the ECG waveform signal to obtain an amplified ECG waveform signal; superimposing and averaging a preset number of heart beats in the ECG waveform signal of each lead in the amplified ECG waveform signal to obtain standard unfiltered signals of leads X, Y and Z; and obtaining a frequency domain diagram based on the standard unfiltered signals of leads X, Y and Z.

[0084] It is understandable that the ECG waveform signal is amplified to obtain an amplified ECG waveform signal. Specifically, the ECG waveform signal is amplified, that is, the ECG waveform signal is processed by a high-gain amplifier to amplify the details of the ECG waveform signal, or other achievable amplification processing methods are all possible, which can be selected according to actual use requirements without specific limitation. The preset number of heart beats in the ECG waveform signal of each lead in the amplified ECG waveform signal are superimposed and averaged to obtain standard unfiltered signals of the X, Y and Z leads. For example, for the ECG waveform signal of the X lead in the amplified ECG waveform signal, a preset number of heart beats are first superimposed and then averaged to obtain a standard unfiltered signal of the X lead; for the ECG waveform signal of the Y lead in the amplified ECG waveform signal, a preset number of heart beats are first superimposed and then averaged to obtain a standard unfiltered signal of the Y lead; for the ECG waveform signal of the Z lead in the amplified ECG waveform signal, a preset number of heart beats are first superimposed and then averaged to obtain a standard unfiltered signal of the Z lead. Thus, a frequency domain graph is obtained based on the standard unfiltered signals of the X, Y and Z leads, and the obtained frequency domain graph is displayed.

[0085] In one embodiment, the time domain graph and the frequency domain graph are displayed separately on the interface W1 of the medical software. For example, the interface W1 of the medical software can be displayed through a display 203 with an interactive function, such as the display 203 can have a touch screen interactive function, that is, touching the corresponding position of the display 203, or clicking the corresponding position with a mouse, can trigger the corresponding function of the medical software, or other triggering methods that can be realized are all possible, without specific limitation.

[0086] Taking the display 203 having a touch screen interactive function as an example, the interface W1 of the medical software is displayed through the display 203, and the interface W1 of the medical software includes a first control W13 and a second control W14. The first control W13 is used for the time domain graph W11, that is, the first control W13 corresponds to the time domain graph W11, and the second control W14 is used for the frequency domain graph W12, that is, the second control W14 corresponds to the frequency domain graph W12. The first control W13 and the second control W14 are displayed at preset positions on the interface W1 of the medical software. For example, the display positions of the first control W13 and the second control W14 can be parallel or separate, without specific limitation.

[0087] Please refer again Figure 4 , in response to the instruction to trigger the first control W13, the time domain graph W11 is displayed on the interface W1 of the medical software. It can be understood that the triggering of the first control W13 can be triggered by clicking the location of the first control W13, for example, by clicking the location of the first control W13 with a mouse, or touching the location of the first control W13 on the display 203, or other achievable methods, without specific limitation. Among them, the touch method can be single-click touch, double-click touch, or other achievable touch methods, without specific limitation.

[0088] Figure 8 is a schematic diagram of a second scene displayed on the interface in an embodiment of the present application, such as Figure 8 As shown, in response to the instruction to trigger the second control W14, the frequency domain graph W12 is displayed on the interface W1 of the medical software. It can be understood that the triggering of the second control W14 can be triggered by clicking the location of the second control W14, for example, by clicking the location of the second control W14 with a mouse, or touching the location of the second control W14 on the display 203, or other achievable methods, without specific limitation. Among them, the touch method can be single-click touch, double-click touch, or other achievable touch methods, without specific limitation.

[0089] Specifically, the first control W13 and the second control W14 can have different display forms to distinguish them and facilitate viewing. Different display forms can include color changes, shape changes, or other achievable display forms, without specific limitation. For example, the first control W13 and the second control W14 both have two display colors, dark and light. When the first control W13 is triggered, the color of the first control W13 is controlled to change from light to dark, and the color of the second control W14 is controlled to change from dark to light, indicating that the current first control W13 is triggered, and the time domain graph W11 is displayed on the interface W1 of the medical software; when the second control W14 is triggered, the color of the second control W14 is controlled to change from light to dark, and the color of the first control W13 is controlled to change from dark to light, indicating that the current second control W14 is triggered, and the frequency domain graph W12 is displayed on the interface W1 of the medical software.

[0090] In one embodiment of the present application, displaying a time domain graph and / or a frequency domain graph also includes: obtaining a second analysis parameter and a value thereof of a standard unfiltered signal of the currently displayed X, Y or Z lead; and displaying the second analysis parameter and a value thereof in a preset manner, wherein the second analysis parameter and a value thereof are displayed simultaneously with the frequency domain graph.

[0091] The second analysis parameter and its value of the standard unfiltered signal of the currently displayed X, Y or Z lead are obtained, and the second analysis parameter and its value are obtained by measuring the standard unfiltered signal of the X, Y or Z lead. It can be understood that the corresponding second analysis parameter and the specific value of the second analysis parameter can be obtained by measuring the standard unfiltered signal of the X, Y or Z lead. The second analysis parameter can include multiple parameters, such as heart rate, noise, or other parameters that can be analyzed, without specific limitation.

[0092] Please refer again Figure 8 , display the second analysis parameter and its value in a preset manner. It can be understood that the measured second analysis parameter and its value can be displayed explicitly in a preset manner. For example, the second analysis parameter and its value are controlled to be displayed explicitly in the second analysis parameter display box W17 in a preset manner. The second analysis parameter and its value can be controlled to be displayed explicitly in two parameter columns, and each parameter row displays a second analysis parameter and its value.

[0093] The second analysis parameter and its value are displayed together with the frequency domain graph W12. Please refer to the figure again for understanding. Figure 8 The second analysis parameter and its value are displayed in the second analysis parameter display box W17. The second analysis parameter display box W17 and the frequency domain diagram W12 are simultaneously displayed on the interface W1 of the medical software, so as to facilitate simultaneous comparison and viewing.

Figure 9(a) to Figure 9(c) As shown, the frequency domain graph W12 includes standard unfiltered signals (W121, W122, W123) of the X, Y and Z leads, and also includes three three-dimensional spectrograms (W124, W125, W126). Among them, the first starting point mark line F1 and the first end point mark line F2 are displayed on the standard unfiltered signal of the X, Y or Z lead currently displayed, the standard unfiltered signal W121 of the X lead and the three-dimensional spectrogram W124 of the X lead are displayed side by side; the standard unfiltered signal W122 of the Y lead and the three-dimensional spectrogram W125 of the Y lead are displayed side by side; the standard unfiltered signal W123 of the Z lead and the three-dimensional spectrogram W126 of the Z lead are displayed side by side.

[0095] The frequency domain graph W12 also includes a preset second selection bar W127, and the preset second selection bar W137 corresponds to the standard unfiltered signal W121 of the X lead, the standard unfiltered signal W122 of the Y lead, and the standard unfiltered signal W123 of the Z lead; in addition, the three-dimensional spectrum graph W124 of the X lead corresponds to the standard unfiltered signal W121 of the X lead, the three-dimensional spectrum graph W125 of the Y lead corresponds to the standard unfiltered signal W122 of the Y lead, and the three-dimensional spectrum graph W126 of the Z lead corresponds to the standard unfiltered signal W123 of the Z lead. That is, the position of the preset second selection bar W127 is changed to trigger the implicitly displayed unfiltered ECG waveform signal and the three-dimensional spectrum graph to be displayed explicitly, thereby explicitly displaying the corresponding unfiltered ECG waveform signal (W121, W122, W123) and the three-dimensional spectrum graph (W124, W125, W126).

[0096] Taking the display 203 having a touch screen interactive function as an example, the interface W1 of the medical software is displayed and presented through the display 203, and the interface W1 of the medical software includes a frequency domain graph W12. Please refer to Figure 9(a) again, the frequency domain graph W12 initially explicitly displays the three-dimensional spectrum graph W124 of the X lead and the standard unfiltered signal W121 of the X lead, and explicitly displays the related information of the three-dimensional spectrum graph W124 of the X lead and the standard unfiltered signal W121 of the X lead, and the ECG waveform signals of the other leads are implicitly displayed, and the preset second selection bar W127 is set in the vertical direction.

[0097] The instruction to trigger the implicitly displayed standard unfiltered signal and the three-dimensional spectrum diagram to be displayed explicitly can be triggered by clicking the location of the preset second selection bar W127 with a mouse, or by touching the location of the preset second selection bar W127 on the display 203, or other triggering methods that can be implemented are all acceptable, and are not specifically limited. For example, the location of the preset second selection bar W127 on the touch display 203 is long pressed and dragged to control the corresponding implicitly displayed standard unfiltered signal and the three-dimensional spectrum diagram to be displayed explicitly.

[0098] Please refer to Figure 9(b) again. In response to the trigger instruction of dragging the preset second selection bar W127 downward, the standard unfiltered signal W122 of the Y lead and the three-dimensional spectrum diagram W125 of the Y lead are controlled to be displayed explicitly, and the relevant information of the standard unfiltered signal W122 of the Y lead and the three-dimensional spectrum diagram W125 of the Y lead is displayed explicitly, and the standard unfiltered signals of the remaining leads are controlled to be displayed implicitly.

In addition, dragging the preset second selection bar W127 upward can also trigger the instruction, thereby controlling the standard unfiltered signal and the three-dimensional spectrum diagram of the corresponding lead to be displayed explicitly.

[0100] In some embodiments, the interface W1 of the medical software also displays other analysis results and a confirmation selection box, which can be set according to actual usage requirements without specific limitation.

[0102] Please refer again Figure 8 , Figure 9(a) to Figure 9(c)It can be understood that the first starting point mark line F1 and the first ending point mark line F2 are displayed on the standard unfiltered signal of the currently displayed X, Y or Z lead, and the first starting point mark line F1 and the second starting point mark line F2 are used to calculate the value of the second analysis parameter. For example, by measuring and calculating the corresponding second analysis parameter on the standard unfiltered signal W121 of the X lead, the value of the second analysis parameter of the X lead can be obtained; by measuring and calculating the corresponding second analysis parameter on the standard unfiltered signal W122 of the Y lead, the value of the second analysis parameter of the Y lead can be obtained; by measuring and calculating the corresponding second analysis parameter on the standard unfiltered signal W123 of the Z lead, the value of the second analysis parameter of the Z lead can be obtained.

[0103] The first starting point marking line F1 and the first end point marking line F2 are used to calculate the value of the second analysis parameter. When the first starting point marking line F1 or the first end point marking line F2 is moved, it is understandable that the value of the corresponding second analysis parameter will change. In response to the moving operation on either the first starting point marking line F1 or the first end point marking line F2, an updated value of the value of the second analysis parameter is obtained, that is, the value of the second analysis parameter is recalculated based on the moved first starting point marking line F1 and the first end point marking line F2 to obtain an updated value of the value of the second analysis parameter, and the updated value is updated and displayed, for example, the updated value of the value of the second analysis parameter is updated and displayed in the second analysis parameter display box W17.

[0104] In one embodiment of the present application, the method for displaying an ECG signal further includes: in response to a print instruction that triggers the display, printing an analysis report obtained by analyzing the ventricular late potential signal, wherein the analysis report includes a time domain graph and a frequency domain graph.
