Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic diagram of a method for graphically displaying ST-segment data in multi-lead data according to an embodiment of the present invention, as shown in fig. 1, the method mainly includes the following steps:

step 1, acquiring a multi-lead data set;

wherein the multi-lead data set comprises a plurality of first lead data sets; the first lead data set includes first lead type data and first lead electrocardiographic sampling data.

Here, the multi-lead data set is a set of multi-lead electrocardiographic data obtained from an electrocardiographic signal acquisition device or a storage device or medium storing electrocardiographic signal data; for example, the multi-lead data set is collected 12-lead data, the multi-lead data set includes 12 first-lead data sets, 12 first-lead data in the 12 first-lead data sets are respectively an aVL lead type, an I lead type, an aVR lead type, a ii lead type, an aVF lead type, a iii lead type, a V1 lead type, a V2 lead type, a V3 lead type, a V4 lead type, a V5 lead type, and a V6 lead type, and 12 first-lead electrocardiograph sampling data in the 12 first-lead data sets are electrocardiograph sampling data collected corresponding to different lead ends.

And 2, performing ST-segment data measurement processing on each first lead electrocardio sampling data to obtain corresponding first lead ST-segment data.

Here, the ST-segment data measurement processing means that, according to a conventional processing manner, after the heart electric data is subjected to drift removal and noise reduction, the potential difference between the ST-segment start reference point and the ST-segment end reference point is calculated, the ST-segment data is 0 in a conventional case or the fluctuation range of positive and negative values is smaller than a specified normal threshold range, the ST-segment data is called ST elevation if the ST-segment data is positive and is higher than an unconventional elevation threshold, and the ST-segment data is called ST depression if the ST-segment data is negative and is lower than an unconventional depression threshold. The ST section data in the electrocardio data of different lead types can also have difference corresponding to several threshold ranges. The method provided by the embodiment of the invention displays the ST-section data in the electrocardiogram data with different lead types by using the frontal annular diagram and the transverse annular diagram respectively, so that medical personnel can judge the ST-section data change more intuitively and quickly.

For example, a multi-lead data set is 12-lead data collected, and 12 ST-segment data measurements are performed 12 times to obtain 12 first-lead ST-segment data corresponding to the 12 leads, as shown in table one.

Step 3, acquiring a first corresponding relation table reflecting the corresponding relation between the lead type and the angle of the frontal plane annular chart, and carrying out frontal plane chart display processing on first lead ST section data corresponding to the first corresponding relation table;

here, as shown in fig. 2a, which is a two-dimensional frontal plane annular diagram of multi-lead ST segment data provided by the first embodiment of the present invention, the frontal plane annular diagram is used for showing ST segment data changes in limb lead data in the multi-lead data; the initial voltage unit value and the initial maximum voltage value are used for calculating the radius of a circular ring of a frontal plane circular diagram, and the embodiment of the invention supports the self-adaptive adjustment of the radius of the circular ring according to the measured first lead ST segment data; the first corresponding relation table gives the lead types corresponding to the frontal plane annular diagram on one hand, and gives the positive and negative direction angles of the lead number axis of each lead type on the frontal plane annular diagram on the other hand; after the number axis of each lead is drawn on the frontal plane annular graph, marking on the axis according to ST-segment data corresponding to each lead; after marking all ST points, sequentially connecting non-negative ST points and the circle center to form a first coverage area, sequentially connecting negative ST points and the circle center to form a second coverage area, and respectively performing color filling processing on the two areas; on the two-dimensional frontal plane annular diagram after color filling, the specific values of ST segment data corresponding to each lead can be intuitively obtained, the change trend of the ST segment data among the leads can be seen, the number of positive and negative ST segment data can be counted, and for medical personnel, the counting and calculating time of the medical personnel is saved, and the data analysis efficiency of the medical personnel is improved;

the method specifically comprises the following steps: step 31, acquiring a first corresponding relation table reflecting the corresponding relation between the lead type and the angle of the frontal plane annular chart;

wherein the first correspondence table includes a plurality of first correspondence records; the first corresponding relation record comprises first lead type information, first positive direction angle information and first negative direction angle information;

here, the first correspondence table corresponds to a plurality of lead types of the limb lead data in the multi-lead data: the system comprises an aVL lead type, an I lead type, an aVR lead type, an II lead type, an aVF lead type and a III lead type, wherein each first corresponding relation record corresponds to a specific lead type data, and the first positive and negative direction angle information is used for marking the positive and negative directions of the numerical value of the subsequent lead number axis;

for example, the multi-lead data set is collected 12-lead data, the limb lead data is aVL lead type, I lead type, -aVR lead type, ii lead type, aVF lead type and iii lead type, and the content of the first correspondence table is as shown in table two;

Step 32, extracting the maximum absolute value from the first lead ST segment data corresponding to the first corresponding relation table to generate first ST maximum data;

for example, first lead ST segment data corresponding to 12 lead data is shown in table one, and a first correspondence table is shown in table two, and then, in the 12 lead data, 6 first lead ST segment data corresponding to 6 lead types (aVL lead type, I lead type, -aVR lead type, ii lead type, aVF lead type, and iii lead type) in the first correspondence table are: -0.13 mv, -0.14 mv, -0.08 mv, -0.02 mv, 0.05 mv and 0.12 mv, the maximum absolute value of the 6 ST segment data being 0.14 mv, then the first ST maximum data =0.14 mv;

step 33, creating a frontal plane annular graph according to a preset initial voltage unit value, an initial maximum voltage value and first ST maximum data;

the method can flexibly adjust the radius of the frontal plane annular diagram according to the ST-segment data measured each time, so that the situation that the display range of the frontal plane annular diagram cannot be exceeded even if data are abnormal can be guaranteed;

the method specifically comprises the following steps: step 331, when the first ST maximum data is less than or equal to the initial maximum voltage value, setting the frontal plane graph maximum voltage data as the initial maximum voltage value, and setting the frontal plane graph voltage unit data as the initial voltage unit value; when the first ST maximum data is greater than the initial maximum voltage value, calculating to generate a frontal plane graph maximum voltage data = the first ST maximum data × the first multiple according to the first ST maximum data and a preset first multiple, and then calculating to generate a frontal plane graph voltage unit data = the frontal plane graph maximum voltage data/the first total according to the frontal plane graph maximum voltage data and a preset first total;

here, the initial voltage unit value and the initial maximum voltage value are a pair of preset voltage values, and the maximum absolute value of the currently acquired ST-segment data of the first leads is the first ST-maximum data; when the first ST maximum data does not exceed the initial maximum voltage value, self-adaptive adjustment is not needed, and the frontal plane graph voltage unit data and the frontal plane graph maximum voltage data are set by adopting a default value: the method comprises the following steps that (1) frontal plane graph voltage unit data = an initial voltage unit value, and frontal plane graph maximum voltage data = an initial maximum voltage value; when the first ST maximum data exceeds the initial maximum voltage value, adaptive adjustment is required: frontal plane voltage data = first ST maximum data × first multiple, frontal plane voltage unit data = frontal plane maximum voltage data/first total; the first total number is shown in fig. 2a, and is actually the number of concentric circles of the frontal plane annular diagram, and is set to 3 by default; the first multiple is conventionally set to 2 by default;

for example, if the initial voltage unit value is 0.1 mv, the initial maximum voltage value is 0.3 mv, and the first ST maximum data is 0.14 mv, no adaptive adjustment is required, the forehead image voltage unit data =0.1 mv, and the forehead image maximum voltage data =0.3 mv;

step 332, creating a frontal plane annular graph according to the frontal plane graph voltage unit data and the frontal plane graph maximum voltage data;

wherein the frontal plane annular map comprises a first total number of first concentric circles; the radius of each first concentric circle is integral multiple of voltage unit data of the frontal plane graph; the radius of the smallest first concentric circle is the voltage unit data of the frontal plane graph, and the radius of the largest first concentric circle is the maximum voltage data of the frontal plane graph;

here, the concentric circles on the frontal plane annular diagram are actually similar to equipotential lines, and the absolute values of the potentials at points on the same circumference are all equal;

for example, the first total number is 3, the frontal plane annular diagram is shown in fig. 2a, and includes 3 first concentric circles, and the radius of the smallest first concentric circle is the voltage unit data of the frontal plane diagram: 0.1 mv, the radius of the largest first concentric circle is the frontal plane graph maximum voltage data: 0.3 mv, the radius of the middle 2 nd first concentric circle should be 0.2 mv;

step 34, performing frontal plane image ST point labeling processing on the first lead ST segment data corresponding to the first corresponding relation table on the frontal plane annular image to obtain corresponding first lead frontal plane image ST points;

here, first, a plurality of first lead frontal plane graph axes are drawn on the frontal plane annular graph according to a first corresponding relation table, and each lead frontal plane graph axis corresponds to one lead type; because the ST segment data has positive and negative, the first lead frontal plane map axis also has positive and negative, where: the forward direction of the first lead frontal plane graph number axis is the direction from the circle center to a first forward direction angle point, and the value range of points on the forward line segment of the first lead frontal plane graph number axis is from 0 to the maximum voltage data of the frontal plane graph; the negative direction of the numerical axis of the first lead frontal plane graph is in the direction from the circle center to a first negative direction angle point, and the value range of points on the negative direction line segment of the numerical axis of the first lead frontal plane graph is from 0 to the negative number of the maximum voltage data of the frontal plane graph; after the first lead frontal plane image number axes of all lead types are drawn, marking the ST segment data of each lead type on the corresponding first lead frontal plane image number axis, wherein the marked point is the first lead frontal plane image ST point;

the method specifically comprises the following steps: step 341, polling the first mapping relation record in the first mapping relation table, and using the currently polled first mapping relation record as a first record;

here, as shown in FIG. 2b, which is a two-dimensional cross-sectional annular diagram of multi-lead ST segment data provided by the first embodiment of the present invention, the cross-sectional annular diagram is used to show the ST segment data variation in chest lead data in multi-lead data; the initial voltage unit value and the initial maximum voltage value are used for calculating the radius of a circular ring of a transverse plane circular diagram, and the embodiment of the invention supports the self-adaptive adjustment of the radius of the circular ring according to measured first lead ST section data; the second corresponding relation table gives the lead types corresponding to the transverse annular diagram on one hand, and gives the positive and negative direction angles of the lead number axis of each lead type on the transverse annular diagram on the other hand; after axes of each lead are drawn on the horizontal annular graph, marking the axes according to ST-segment data corresponding to each lead; after marking all the ST points, sequentially connecting the non-negative ST points and the circle center to form a third coverage area, sequentially connecting the negative ST points and the circle center to form a fourth coverage area, and respectively performing color filling processing on the two areas; on the two-dimensional transverse plane annular diagram after color filling is completed, the specific values of ST segment data corresponding to each lead can be intuitively obtained, the change trend of the ST segment data among the leads can be seen, the number of positive and negative ST segment data can be counted, and for medical personnel, the counting and calculating time of the medical personnel is saved, and the data analysis efficiency of the medical personnel is improved;

the method specifically comprises the following steps: step 41, acquiring a second corresponding relation table reflecting the corresponding relation between the lead type and the angle of the transverse annular graph;

the second corresponding relation table comprises a plurality of second corresponding relation records; the second corresponding relation record comprises second lead type information, second positive direction angle information and second negative direction angle information;

here, the second correspondence table corresponds to a plurality of lead types (V1 lead type, V2 lead type, V3 lead type, V4 lead type, V5 lead type, and V6 lead type) of the chest lead data in the multi-lead data, each second correspondence table records data corresponding to one specific lead type, and the second positive and negative direction angle information is used for labeling the positive and negative directions of the numerical value of the subsequent lead number axis.

For example, the multi-lead data set is collected 12-lead data, the chest lead data is a V1 lead type, a V2 lead type, a V3 lead type, a V4 lead type, a V5 lead type and a V6 lead type, and the contents of the second correspondence table are shown in table three;

Step 42, extracting the maximum absolute value from the first lead ST segment data corresponding to the second corresponding relation table to generate second ST maximum data;

for example, first lead ST segment data corresponding to 12 lead data is shown in table one, and a second correspondence table is shown in table three, and then 6 first lead ST segment data corresponding to 6 lead types (V1 lead type, V2 lead type, V3 lead type, V4 lead type, V5 lead type, and V6 lead type) in the second correspondence table in the 12 lead data are respectively: 0.1 mv, 0.02 mv, -0.15 mv, -0.33 mv, -0.29 mv, and-0.16 mv, with the maximum absolute value of 0.33 mv in these 6 ST segment data, then the second ST maximum data =0.33 mv;

step 43, creating a transverse plane annular graph according to the initial voltage unit value, the initial maximum voltage value and the second ST maximum data;

the method can flexibly adjust the radius of the transverse annular diagram according to the ST-segment data measured each time, so that the transverse annular diagram cannot exceed the display range of the transverse annular diagram even if data are abnormal;

the method specifically comprises the following steps: step 431, when the second ST maximum data is less than or equal to the initial maximum voltage value, setting the cross plane graph maximum voltage data as the initial maximum voltage value, and setting the cross plane graph voltage unit data as the initial voltage unit value; when the second ST maximum data is larger than the initial maximum voltage value, calculating to generate cross-plane graph maximum voltage data = second ST maximum data × first multiple according to the second ST maximum data and the first multiple, and then calculating to generate cross-plane graph voltage unit data = cross-plane graph maximum voltage data/first total according to the cross-plane graph maximum voltage data and the first total;

here, the initial voltage unit value and the initial maximum voltage value are a pair of preset voltage values, and the maximum absolute value of the currently acquired ST-segment data of the plurality of first leads is the second ST-maximum data; when the second ST maximum data does not exceed the initial maximum voltage value, self-adaptive adjustment is not needed, and the voltage unit data of the transverse plane diagram and the maximum voltage data of the transverse plane diagram are set by adopting a default value: horizontal graph voltage unit data = initial voltage unit value, and horizontal graph maximum voltage data = initial maximum voltage value; when the second ST maximum data exceeds the initial maximum voltage value, adaptive adjustment is required: maximum voltage data of the cross section map = second ST maximum data × first multiple, voltage unit data of the cross section map = maximum voltage data of the cross section map/first total number; the first total number is shown in fig. 2b, the first total number is actually the number of concentric circles of the horizontal plane annular diagram, and is set to 3 by default; the first multiple is normally set to 2 by default;

for example, the initial voltage unit value is 0.1 mv, the initial maximum voltage value is 0.3 mv, the second ST maximum data is 0.33 mv, and adaptive adjustment is required, the cross-sectional view maximum voltage data = the second ST maximum data = first multiple =0.33 × 2=0.66 (mv), the cross-sectional view voltage unit data = the cross-sectional view maximum voltage data/first total =0.66/3=0.22 (mv); when division is carried out, incomplete division can be met, and if incomplete division is met, rounding processing is carried out on the voltage unit data of the cross-plane diagram under the condition that the accuracy of the voltage unit data of the cross-plane diagram is consistent with that of the voltage unit data of the cross-plane diagram;

step 432, creating a transverse plane annular diagram according to the transverse plane diagram voltage unit data and the transverse plane diagram maximum voltage data;

wherein the cross-plane annular map comprises a first plurality of second concentric circles; the radius of each second concentric circle is integral multiple of the voltage unit data of the transverse plane graph; the radius of the smallest second concentric circle is transverse graph voltage unit data, and the radius of the largest second concentric circle is transverse graph maximum voltage data;

here, the concentric circles on the transverse plane annular diagram are actually similar to equipotential lines, and the absolute values of the potentials at points on the same circumference are all equal;

for example, the first total number is 3, the cross-plane annular map, as shown in fig. 2b, includes 3 second concentric circles, and the smallest second concentric circle has a radius of the cross-plane map voltage unit data: 0.22 mv, the radius of the largest second concentric circle is the maximum voltage data for the cross-sectional view: 0.66 mv, the radius of the middle 2 nd second concentric circle should be 0.44 mv;
