Description

Technical Field

[0001] This invention relates to the field of electrocardiography (ECG) technology, and more particularly to a method, system, storage medium, and smart terminal for displaying ST segment deviation. Background Technology

[0002] ST segment changes are quite common on electrocardiograms. They begin at the J point and terminate at the beginning of the T wave, appearing smooth and concave upwards. Although the ST segment occupies a relatively short time in a cardiac cycle, it is of great clinical significance. ST segment deviation is related not only to physiological factors (such as exercise and emotional excitement) but also to pathological factors, and most ST segment deviations have some clinical significance. Therefore, the display of ST segment deviation values ​​is particularly important.

[0003] Traditional ST segment display methods directly present the complete QRS waveform and real-time ST value of each ST lead. Medical staff will analyze the patient's physiological characteristics based on ST segment depression, ST segment elevation, ST segment time, or ST segment offset morphology. This method cannot display the range of ST segment offset values ​​in each lead, the changes in ST segment offset values, etc. Summary of the Invention

[0004] Based on this, it is necessary to propose an ST segment offset display method, system, storage medium, and intelligent terminal to address the above problems.

[0005] A method for displaying ST segment offset, the method comprising:

[0006] Several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values ​​were determined based on physiological signals under different leads.

[0007] The real-time offset region of the ST segment under different leads is displayed by the aforementioned sets of ST segment real-time offset values.

[0008] The ST segment's shift range under different leads is displayed by several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values.

[0009] The method of displaying the real-time offset region of the ST segment under different leads through the plurality of sets of real-time ST segment offset values ​​specifically includes:

[0010] Determine the comparison between the current ST real-time offset value and the zero potential among the several groups of ST segment real-time offset values.

[0011] The real-time offset region for different lead types is determined based on the comparison between the current real-time offset value of the ST segment and the zero potential.

[0012] Specifically, determining the real-time offset region for different lead types based on the comparison between the current ST segment real-time offset value and zero potential includes:

[0013] The vertical midline of the real-time offset circular histogram is determined based on different lead types.

[0014] If the current ST segment real-time offset value is greater than the zero potential, then a real-time offset region corresponding to the lead type is drawn to the right of the vertical centerline of the real-time offset annular bar chart according to the radian value corresponding to the current ST segment real-time offset value.

[0015] If the current ST segment real-time offset value is less than the zero potential, then a real-time offset region corresponding to the lead type is drawn to the left of the vertical centerline of the real-time offset annular bar chart according to the radian value corresponding to the current ST segment real-time offset value.

[0016] Specifically, displaying the ST segment's shift range under different leads using the aforementioned sets of real-time ST segment offset values ​​and the aforementioned sets of ST segment change offset values ​​includes:

[0017] The reference offset region is determined based on the aforementioned sets of ST segment change offset values.

[0018] Determine the comparison between the current ST segment change offset value and the zero potential among the several groups of ST segment change offset values, and determine the change offset region under different leads, taking the end point of the reference offset region as the starting point.

[0019] Specifically, determining the reference offset region based on the aforementioned sets of ST segment change offset values ​​includes:

[0020] The ST segment change offset value with the smallest absolute value is determined based on the aforementioned groups of ST segment change offset values, and the real-time ST segment offset value corresponding to the ST segment change offset value with the smallest absolute value is the baseline value.

[0021] Determine the comparison between the baseline value and zero potential.

[0022] The reference offset region is determined based on the comparison between the baseline value and the zero potential.

[0023] Specifically, determining the reference offset region based on the comparison between the baseline value and zero potential includes:

[0024] The vertical midline of the variable offset annular histogram is determined based on different lead types.

[0025] If the baseline value is greater than the zero potential, then a reference offset region is drawn to the right of the vertical central axis of the annular bar chart corresponding to the baseline value.

[0026] If the baseline value is less than the zero potential, then a reference offset region is drawn to the left of the vertical central axis of the annular bar chart corresponding to the baseline value.

[0027] Specifically, determining the comparison between the current ST segment shift value and the zero potential in the plurality of ST segment shift values, and determining the shift region under different leads with the end point of the reference shift region as the starting point, includes:

[0028] If the current ST segment change offset value is greater than the zero potential among the several groups of ST segment change offset values, then draw the change offset region corresponding to the lead type to the right of the endpoint of the reference offset region according to the radian corresponding to the current ST segment change offset value;

[0029] If the current ST segment change offset value is determined to be less than the zero potential among the several groups of ST segment change offset values, then a change offset region corresponding to the lead type is drawn to the left of the endpoint of the reference offset region according to the radian corresponding to the current ST segment change offset value.

[0030] An ST segment offset display system, the system comprising:

[0031] The ST segment real-time offset value and ST segment change offset value determination module is used to determine several sets of ST segment real-time offset values ​​and several sets of ST segment change offset values ​​based on physiological signals under different leads.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0051] like Figure 1 As shown, Figure 1 This is a flowchart illustrating an embodiment of an ST segment offset display method provided by the present invention. An ST segment offset display method includes:

[0052] S101: Determine several sets of real-time ST segment offset values ​​and several sets of ST segment change offsets based on physiological signals under different leads.

[0053] In a specific application scenario, electrocardiographs (ECGs) can analyze and differentiate various arrhythmias, diagnose myocardial infarction and acute coronary insufficiency, assist in the diagnosis of chronic coronary insufficiency, myocarditis, and cardiomyopathy; determine the presence of atrial and ventricular hypertrophy, assist in the diagnosis of pericardial diseases; observe the effects of certain drugs on the heart, and assist in the diagnosis of certain electrolyte imbalances, especially excessive or insufficient potassium and calcium levels. In recent years, due to population aging and unhealthy lifestyles, the number of heart disease patients has been increasing, leading to a continuous increase in the demand for ECGs. Market research reports indicate that 12-lead ECGs offer simple testing methods and rapid results. Compared to 6-lead or 3-lead ECGs, 12-lead ECGs can display all leads on the same page, allowing users to compare waveform changes in each lead from multiple angles and levels in greater detail, identifying subtle ECG abnormalities. Furthermore, the waveforms produced by 12-lead ECGs are more stable, regular, and easier to save. Based on these advantages, the market size for 12-lead ECGs is continuously expanding.

[0054] A 12-lead electrocardiograph simultaneously records and displays the physiological signals of all twelve leads. The P wave, QRS complex, and T wave are determined based on these signals. Within one cardiac cycle, the isoelectric line from the end of the QRS complex to the beginning of the T wave is called the ST segment. ST segment depression indicates myocardial ischemia, while ST segment elevation indicates myocardial infarction or early repolarization. Several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values ​​are recorded.

[0055] S102: Displays the real-time offset area of ​​the ST segment under different leads through several sets of real-time ST segment offset values.

[0056] In a specific implementation scenario, clinical practice routinely uses 10 leads with 12 different lead connections to record a 12-lead electrocardiogram (ECG). This includes three classic, standard bipolar limb leads (leads I, II, and III); three unipolar limb leads (aVR, aVL, and aVF); and six unipolar chest wall leads (V1, V2, V3, V4, V5, and V6). First, the vertical midline of the real-time offset circular histogram is determined based on the different lead types. For example... Figure 2 As shown, Figure 2 This is a ring-shaped histogram of the real-time offset region under twelve leads provided by the present invention. Figure 2 This is a circular histogram showing the real-time offset region in twelve leads under normal conditions when the current ST segment real-time offset value is greater than zero potential. The horizontal midline represents the ST segment real-time offset value, and the vertical midline represents different leads. The maximum ST segment offset is 2.5mV, and the minimum offset is -2.5mV. Further, using the vertical midline as the starting position of the ST segment real-time offset value, the comparison between the current ST segment real-time offset value and zero potential is determined among several sets of ST segment real-time offset values. If the current ST segment real-time offset value is greater than zero potential, a real-time offset region corresponding to the lead type is drawn to the right of the vertical midline of the real-time offset circular histogram based on the arc corresponding to the current ST segment real-time offset value. If the current ST segment real-time offset value is less than zero potential, a real-time offset region corresponding to the lead type is drawn to the left of the vertical midline of the real-time offset circular histogram based on the arc corresponding to the current ST segment real-time value. The real-time offset region is shown below. Figure 2 The area is filled with a diagonal line, as shown.

[0057] Preferably, during the process of plotting the real-time offset region, the radian of the current ST segment's real-time offset value in the annular histogram is determined according to the following formula:

[0058] Curve of leads above the horizontal midline:

[0059] α1 = π / 2 - ST*π / (2.5*2);

[0060] Curve of the leads below the horizontal midline:

[0061] α1 = π*3 / 2 + ST*π / (2.5*2);

[0062] Where α1 is the radian corresponding to the current real-time offset value of the ST segment, and ST is the current real-time offset value of the ST segment.

[0063] The final real-time offset region is determined based on the start and end positions of several sets of ST segment real-time offset values.

[0064] S103: Displays the change offset area of ​​the ST segment under different leads through several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values.

[0065] In an implementation scenario, such as Figure 3 As shown, Figure 3 This is a ring-shaped histogram of the shift region under twelve leads provided by the present invention. Figure 3 This is a circular histogram showing the ST segment offset region under normal conditions, where the baseline value is greater than zero and the current ST segment offset value is greater than zero. The horizontal midline represents the real-time ST segment offset value, and the vertical midline represents different leads. The reference offset region is determined based on several sets of ST segment offset values, as shown below. Figure 3 The area is filled with a diagonal line, as shown.

[0066] Furthermore, the comparison between the current ST segment shift value and zero potential in several groups of ST segment shift values ​​is determined. Using the end point of the reference shift region as the starting point, the shift regions under different leads are determined, as shown in the figure. Figure 3 The area is shown in medium gray fill.

[0067] Specifically, firstly, the vertical midline of the variable offset ring histogram is determined according to different lead types. Based on several sets of real-time ST segment offset values, the ST segment variable offset value with the smallest absolute value is determined and used as the baseline value for the corresponding lead. The starting position of the baseline value is the vertical midline. The comparison between the baseline value and zero potential is determined. If the baseline value is greater than zero potential, a reference offset area is drawn to the right of the vertical midline of the variable offset ring histogram according to the arc corresponding to the baseline value; if the baseline value is less than zero potential, a reference offset area is drawn to the left of the vertical midline of the variable offset ring histogram according to the arc corresponding to the baseline value.

[0068] Preferably, during the process of drawing the reference offset region, the radian corresponding to the baseline value is determined according to the following formula:

[0069] Curve of leads above the horizontal midline:

[0070] α2=π / 2-ST'*π / (2.5*2);

[0071] Curve of the leads below the horizontal midline:

[0072] α2=π*3 / 2+ST'*π / (2.5*2);

[0073] Where α2 is the radian value corresponding to the baseline value, and ST' is the baseline value.

[0074] The final reference offset area is determined based on the start and end positions of the baseline value.

[0075] Furthermore, the comparison between the current ST segment shift value and zero potential among several groups of ST segment shift values ​​is determined. The end position of the baseline value, i.e., the end point of the reference shift region, is taken as the starting position of the ST segment shift value. If the current ST segment shift value is greater than zero potential, a shift region corresponding to the lead type is drawn to the right of the end point of the reference shift region based on the arc corresponding to the current ST segment shift value. The final shift region is from the starting position of the baseline value to the ending position of the ST segment shift value. If the current ST segment shift value is less than zero potential, a shift region corresponding to the lead type is drawn to the left of the end point of the reference shift region based on the arc corresponding to the current ST segment shift value. The final shift region is from the starting position of the baseline value to the ending position of the baseline value.

[0076] Preferably, during the process of drawing the transformation offset region, the radian corresponding to the current ST segment transformation offset value is determined according to the following formula:

[0077] Curve of leads above the horizontal midline:

[0078] α3=π / 2-ST'*π / (2.5*2)-ΔST*π / (2.5*2);

[0079] Curve of the leads below the horizontal midline:

[0080] α3=π*3 / 2+ST'*π / (2.5*2)+ΔST*π / (2.5*2);

[0081] Where α3 is the radian value corresponding to the current ST segment change offset value, and ΔST is the current ST segment change offset value.

[0082] It should be noted that, in Figure 2 and Figure 3 The data to the right of the horizontal midline represents the maximum ST segment offset corresponding to the arc-shaped area from the vertical midline to the right of the horizontal midline. The data to the left of the horizontal midline represents the minimum ST segment offset corresponding to the arc-shaped area from the vertical midline to the left of the horizontal midline. Furthermore, each lead displayed on the vertical midline will dynamically change according to the currently selected lead type, including but not limited to twelve leads, without specific limitations here.

[0083] As described above, displaying the real-time ST segment offset region in different leads using several sets of real-time ST segment offset values ​​allows for direct analysis of the range of ST segment offset values. Furthermore, displaying the changing offset region of the ST segment in different leads using both several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values ​​not only allows for direct analysis of the range of ST segment offset values ​​but also provides a visual representation of the changes in ST segment offset values, facilitating rapid interpretation by doctors and providing a reference for clinical diagnosis of heart disease.

[0084] like Figure 4 As shown, Figure 4 This is a flowchart illustrating another embodiment of the ST segment offset display method provided by the present invention. An ST segment offset display method includes:

[0085] S201: Determine several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values ​​based on physiological signals under different leads.

[0086] In a specific implementation scenario, several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values ​​are determined based on physiological signals under different leads, and displayed in a table, as shown in Table 1. Table 1 shows two sets of real-time ST segment offset values ​​and ST segment change offset values ​​for twelve leads under normal conditions. In Table 1, ST is the real-time ST segment offset value, and ΔST is the ST segment change offset value.

[0087]

[0088] Table 1

[0089] It should be noted that under abnormal conditions, the real-time ST segment offset value and ST segment change offset value corresponding to different leads can be positive or negative. Table 1 only shows two sets of real-time ST segment offset values ​​and ST segment change offset values ​​for twelve leads under normal conditions.

[0090] S202: Determine the comparison between the current ST segment real-time offset value and zero potential among several groups of ST segment real-time offset values, and determine the vertical central axis of the real-time offset annular bar chart according to different lead types.

[0091] S2021: If the current ST segment real-time offset value is greater than zero potential, then draw the real-time offset area corresponding to the lead type to the right of the vertical centerline of the real-time offset annular bar chart according to the radian corresponding to the current ST segment real-time offset value.

[0092] S2022: If the current ST segment real-time offset value is less than zero potential, then draw the real-time offset area corresponding to the lead type to the left of the vertical centerline of the real-time offset annular bar chart according to the radian corresponding to the current ST segment real-time offset value.

[0093] In one implementation scenario, different lead types are used as the vertical central axis of the real-time offset histogram, and the ST segment real-time offset value is used as the horizontal central axis. Based on a comparison of the current ST segment real-time offset value with zero potential among several sets of ST segment real-time offset values, the real-time offset region of the ST segment is plotted in the real-time offset histogram. Specifically, if the current ST segment real-time offset value is greater than zero potential, a real-time offset region corresponding to the lead type is plotted to the right of the vertical central axis of the real-time offset histogram, based on the arc corresponding to the current ST segment real-time offset value; if the current ST segment real-time offset value is less than zero potential, a real-time offset region corresponding to the lead type is plotted to the left of the vertical central axis of the real-time offset histogram, based on the arc corresponding to the current ST segment real-time offset value.

[0094] like Figure 5 As shown, Figure 5 This is a flowchart illustrating another embodiment of the ST segment offset display method provided by the present invention. An ST segment offset display method includes:

[0095] S301: Determine several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values ​​based on physiological signals under different leads.

[0096] It should be noted that step S301 is in Figure 1 and Figure 4 The implementation scenarios shown have been discussed in detail and will not be repeated here.

[0097] S302: Determine the baseline value based on several sets of ST segment change offset values.

[0098] S303: Determine the comparison between the baseline value and zero potential, and determine the vertical midline of the variable offset annular histogram according to different lead types.

[0099] S3031: If the baseline value is greater than zero potential, then draw the reference offset area to the right of the vertical centerline of the circular bar chart corresponding to the baseline value in terms of the radius of curvature.

[0100] S3032: If the baseline value is less than zero potential, then draw the reference offset area to the left of the vertical centerline of the circular bar chart according to the radian angle corresponding to the baseline value.

[0101] In one implementation scenario, different lead types are used as the vertical central axis of the shift histogram, and the real-time ST segment offset value is used as the horizontal central axis. First, a baseline value is determined based on several sets of ST segment shift values. Specifically, the smaller the absolute value of the ST segment shift value among the several sets, the more stable the corresponding real-time ST segment offset value; this value is recorded as the baseline value. Further, a reference offset region for the ST segment is drawn in the shift histogram based on the comparison between the baseline value and zero potential. Specifically, the starting position of the baseline value is the vertical central axis. If the baseline value is greater than zero potential, the reference offset region is drawn to the right of the vertical central axis of the shift histogram based on the arc corresponding to the current real-time ST segment offset value; if the baseline value is less than zero potential, the reference offset region is drawn to the left of the vertical central axis of the shift histogram based on the arc corresponding to the current real-time ST segment offset value.

[0102] S304: Determine the comparison between the current ST segment change offset value and zero potential among several groups of ST segment change offset values, and determine the change offset area under different leads, taking the end point of the reference offset area as the starting point.

[0103] S3041: If the current ST segment change offset value is greater than zero potential among several groups of ST segment change offset values, then draw the change offset area corresponding to the lead type to the right of the endpoint of the reference offset area according to the radian corresponding to the current ST segment change offset value.

[0104] In a specific implementation scenario, such as Figure 6 As shown, Figure 6 This is a ring-shaped bar chart of an embodiment of the variable offset region under a certain lead provided by the present invention. Figure 6 This is a circular histogram showing the shift region in a lead when both the baseline value and the current ST segment shift value are greater than zero potential. The ST segment shift value is ΔST. Once the baseline value is determined to be greater than zero potential, a reference shift region is drawn to the right of the vertical centerline of the shift histogram, based on the radian corresponding to the baseline value. The reference shift region is shown below. Figure 6 The area filled with diagonal lines.

[0105] Furthermore, starting from the end point of the reference offset region (the end position of the baseline value), it is determined that the current ST segment change offset value is greater than zero potential. Based on the arc corresponding to the current ST segment change offset value, an arc-shaped area with a corresponding proportion of gray fill is drawn to the right of the end position of the baseline value. This arc-shaped area is taken as the change offset region of the ST segment, and the end point of the change offset region is the current ST segment real-time offset value.

[0106] S3042: If the current ST segment change offset value is less than zero potential among several groups of ST segment change offset values, then draw the change offset area corresponding to the lead type to the left of the endpoint of the reference offset area according to the radian corresponding to the current ST segment change offset value.

[0107] In a specific implementation scenario, such as Figure 7 As shown, Figure 7 This is a ring-shaped bar chart of another embodiment of the variable offset region under a certain lead provided by the present invention. Figure 6 This is a circular histogram showing the shift region in a lead when the baseline value is greater than zero potential and the current ST segment shift value is less than zero potential. If the baseline value is determined to be greater than zero potential, then a reference shift region is drawn to the right of the vertical center line of the circular histogram based on the radian corresponding to the baseline value. The reference shift region is shown below. Figure 7 The area filled with diagonal lines.

[0108] Furthermore, starting from the end point of the diagonal line-filled area (the end position of the baseline value), it is determined that the current ST segment change offset value is less than zero potential. Based on the arc corresponding to the current ST segment change offset value, a corresponding proportion of arc-shaped area is filled with gray to the left of the end position of the baseline value. This arc-shaped area is taken as the change offset area of ​​the ST segment, and the end point of the change offset area is the end position of the baseline value.

[0109] As described above, this invention displays the real-time ST segment offset region in different leads using several sets of real-time ST segment offset values, allowing direct analysis of the range of ST segment offset values. Furthermore, by displaying the ST segment shift region in different leads using several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values, it not only directly analyzes the range of ST segment offset values ​​but also intuitively displays the changes in the ST segment, facilitating rapid interpretation by doctors and providing a reference for clinical diagnosis of heart disease.

[0110] like Figure 8 As shown, Figure 8 This is a schematic diagram of an embodiment of an ST segment offset display system provided by the present invention. An ST segment offset display system 10, the system includes:

[0111] The ST segment real-time offset value and ST segment change offset value determination module 11 is used to determine several sets of ST segment real-time offset values ​​and several sets of ST segment change offset values ​​based on physiological signals under different leads.

[0112] The real-time offset region display module 12 is used to display the real-time offset region of the ST segment under different leads through several sets of real-time ST segment offset values.

[0113] The variable offset area display module 13 is used to display the variable offset area of ​​the ST segment under different leads through several sets of real-time ST segment offset values ​​and several sets of variable ST segment offset values.

[0114] In a specific implementation scenario, in the ST segment real-time offset value and ST segment change offset value determination module 11, based on the physiological signals under different leads, the ST segment is determined by the isoelectric line between the end of the QRS complex and the beginning of the T wave, and several sets of ST segment real-time offset values ​​and several sets of ST segment change offset values ​​are recorded. Further, in the real-time offset region display module 12, the comparison between the current ST segment real-time offset value and zero potential among several sets of ST segment real-time offset values ​​is determined, and the vertical central axis of the real-time offset annular histogram is determined according to different lead types. If the current ST segment real-time offset value is greater than zero potential, a real-time offset region corresponding to the lead type is drawn to the right of the vertical central axis of the real-time offset annular histogram according to the arc corresponding to the current ST segment real-time offset value; if the current ST segment real-time offset value is less than zero potential, a real-time offset region corresponding to the lead type is drawn to the left of the vertical central axis of the real-time offset annular histogram according to the arc corresponding to the current ST segment real-time offset value. In the variable offset region display module 13, a baseline value is determined based on several sets of ST segment variable offset values. The comparison between the baseline value and zero potential is then determined, and a reference offset region is determined based on this comparison. Specifically, the vertical central axis of the variable offset annular histogram is determined according to different lead types. If the baseline value is greater than zero potential, a reference offset region is drawn to the right of the vertical central axis of the variable offset annular histogram based on the curvature corresponding to the baseline value. If the baseline value is less than zero potential, a reference offset region is drawn to the left of the vertical central axis of the variable offset annular histogram based on the curvature corresponding to the current baseline value. Further, if the current ST segment variable offset value is determined to be greater than zero potential among several sets of ST segment variable offset values, a variable offset region corresponding to the lead type is drawn to the right of the endpoint of the reference offset region based on the curvature corresponding to the current ST segment variable offset value. If the current ST segment variable offset value is determined to be less than zero potential among several sets of ST segment variable offset values, a variable offset region corresponding to the lead type is drawn to the left of the endpoint of the reference offset region based on the curvature corresponding to the current ST segment variable offset value.

[0115] As described above, this invention displays the real-time offset region of the ST segment under different leads by using several sets of real-time ST segment offset values, and displays the changing offset region of the ST segment under different leads by using several sets of real-time ST segment offset values ​​and several sets of ST segment change offset values. It can directly analyze the range of the ST segment offset value, intuitively display the change of the ST segment offset value, and intuitively display the differences between different leads.
