Description

ST segment offset display method and device, electronic equipment and storage medium

Technical Field

The present application relates to the field of cardiac analysis technologies, and in particular, to a method and an apparatus for displaying ST segment offset, an electronic device, and a computer-readable storage medium.

Background

Electrical shock waves beat the heart muscle, which are conducted through the patient's body and can be measured with electrodes attached to the patient's skin. Electrodes on different sides of the heart can measure activity at different sites in the myocardium. The Electrocardiograph (ECG) shows the voltage between electrode pairs (leads) in different directions. Therefore, the electrocardiosignals can display the whole heart rate, the weakness of the cardiac muscle at different parts of the cardiac muscle and the like, and can be used for measuring and diagnosing the abnormal condition of the cardiac rhythm.

When the cardiac muscle of a patient is ischemic or injured, the ST wave part in the electrocardiosignal of the affected lead is shifted, that is, the affected lead may have the ST wave shifted upward from the zero potential difference line, and the other leads may be shifted downward. The physician can identify which myocardial disease is at higher risk by determining the values of the affected lead offsets, and thus pay closer attention to them.

The flat line from the end of QRS complex to the beginning of T wave in ST segment reflects that all parts of ventricle are excited and all parts are in depolarization state, so there is no potential difference. ST-segment shift is an important change seen in myocardial ischemia. The degree of offset and its shape are diagnostically important. In the related art, the ST-segment deviation can be displayed by numerical values, which is not intuitive enough, and it is not easy to quickly see whether the symptom is worsening or improving. In addition, different offset states can be displayed in a superposition mode through bar graphs or bar graphs and the like, only one graphical difference in the longitudinal direction is obvious, and no feature is displayed in the transverse direction, so that the method is not comprehensive and visual. In addition, ST segment deviation can be displayed through a trend graph connected by a broken line, the ST segment deviation is flexible display of ST values, and the extreme processing is not carried out on the characteristics, so that some characteristics are not easy to see from the graph.

Therefore, how to intuitively display the ST segment offset is a technical problem to be solved by those skilled in the art.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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 application. In addition, in the embodiments of the present application, "first", "second", and the like are used for distinguishing similar objects, and are not necessarily used for describing a specific order or a sequential order.

Fig. 1 shows an ecg signal 100 of a heartbeat in a normal ecg signal of a healthy person, which includes a P-wave, a Q-wave, an R-wave, an S-wave, and a T-wave. The P-wave represents atrial depolarization, where the initial portion of the P-wave reflects primarily right atrial depolarization and the terminal portion reflects primarily left atrial depolarization. As can be seen, the Q wave is a downwardly shifted wave after the P wave. A typical Q wave represents cardioseptal depolarization. The R-wave is the first upwardly shifted wave after the P-wave, which represents early ventricular depolarization. The S-wave is the first negatively-shifted wave after the R-wave, which represents late ventricular depolarization. The T-wave is generally convex, slightly rounded, and slightly asymmetric. The T wave represents repolarization of the ventricles. The QRS complex 110 begins at the start of the Q wave and ends at the end of the S wave. The QRS complex 110 represents the duration of ventricular depolarization.

Generally, there is little or no electrical activity along the zero-potential-difference line 112 during the PR segment 114 and ST segment 116 of the electrocardiosignal 100. The PR segment 114 begins at the end of the P wave and ends at the beginning of the QRS complex. During the PR segment, electrical pulses are conducted from the AV node through the conducting tissue (bundle support and purkinje fibers) to the ventricle. Thus, the PR segment 114 corresponds to the time it takes for an electrical pulse to reach the ventricles from the AV node. Most of the delay of the PR segment 114 occurs at the AV node. The ST segment 116 begins at the end of the S-wave and ends at the beginning of the T-wave. During ST segment 116, atrial cells relax and the ventricles contract, and thus electrical activity may not be visible. In other words, as previously indicated, ST waves 116 are normally zero potential difference.

In normal conditions, the ST segment is close to an equipotential line, downward deviation should not exceed 0.05 mV, upward deviation in limb leads should not exceed 0.1mV, and V1, V2 and V3 in unipolar precordial leads can reach 0.2-0.3 mV; rarely above 0.1mv in the V4, V5 leads. In any normal precordial cascade, the ST drop should not be less than 0.05 mv. If the height is higher or lower than the above range, the electrocardiogram belongs to abnormal electrocardiogram.

ST-segment shift is an important change seen in myocardial ischemia. The degree of offset and its shape are diagnostically important. ST segment elevation occurs when myocardial damage is located epicardially, or when damage spreads from the endocardial side to the epicardial side (transmural myocardial damage). When there is only endocardial side damage (endocardial sub-myocardial damage), the electrocardiogram taken at the body surface shows a drop in ST segment.

Fig. 2A and 2B show electrocardiographic signals 210 and 212 representing one heartbeat, respectively, which are different from the "typical" electrocardiographic signal 100. As shown in fig. 2A and 2B, the ST segment 116 may appear to be raised (fig. 2A) or lowered (fig. 2B) in the vertical direction from the zero-potential-difference line 112. ST elevation or depression may be caused by heart injury, ventricular wall tumors, variant angina, pericarditis, myocardial ischemia, or other conditions. The skilled artisan will appreciate from the description herein that the elevation of the ST segment in fig. 2A and the depression of the ST segment in fig. 2B may still occur for the same patient when detected by different leads.

Fig. 2A and 2B also show the location of the respective J point 214 and ST point 216. The J point 214 is the junction of the QRS complex 110 and the ST segment 116. ST point 216 defines a selected time period from J point 214 at which the amplitude of the ST segment is measured. For example, typically the ST segment is measured at a location approximately "1/16R-R interval" after J, where R-R interval is the interval between heartbeats or the distance from a selected point on the cardiac electrical signal of one heartbeat to the corresponding point on the cardiac electrical signal of the next heartbeat. For example, in the case of a heart rate of about 60 beats per minute, this corresponds to 60 milliseconds after the J point. Generally, the ST point 216 is selected to be between about 40 milliseconds and about 80 milliseconds after the J point.

As shown in fig. 2A and 2B, the ST-segment offset 218 is the vertical distance between the zero-potential-difference line 112 and the ST point 216. The voltage (vertical distance) between the zero potential difference line 112 and the ST point 216 is typically in the order of microvolts. However, typically the ECG signal is recorded on strip chart paper (not shown), the scale recorded is typically 1cm/mV, and the ST segment is typically read in millimeters, where 1mm equals 0.1mV.

The shift values in millimeters for the ST segment are typically displayed in the ecg signal area of the monitor or in a separate ST parameter area. For example, FIG. 3A is a user interface 300 for a monitor (not shown) in which ST segment offset values (in millimeters) for a plurality of leads are displayed. However, the method of viewing the numerical values on user interface 300 is not the easiest or fastest method to integrate information for several leads (e.g., leads I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, and V6) and determine whether there is myocardial ischemia and the likely location of myocardial ischemia.

As shown in fig. 3A, such a display may be overly cluttered, which may make it difficult to quickly obtain important or critical information from the user interface 300. Moreover, the typical user interface 300 that provides numerical information of the current ST segment offset value does not provide information that can help the user determine whether myocardial ischemia is improving or worsening because it does not display any initial or baseline ST segment offset values. As shown in fig. 3B, providing this information, in turn, makes the user interface 300 of fig. 3 more cluttered because it requires 24 values to be displayed instead of 12. In fig. 3B, the user interface 300 displays the initial ST-segment offset (in parenthesis) and the current ST-segment offset.

ST-segment deviation can also be represented by overlaying a baseline cardiac signal on the current cardiac signal. For example, FIG. 4 is a user interface 400 of a monitor (not shown) showing baseline and current cardiac electrical signals for three different leads (e.g., lead II, aVR, V1). In the example of fig. 4, the baseline electrocardiographic signal is indicated by a dashed line, and the current electrocardiographic signal is indicated by a solid line. The user may manually determine the ST-segment offsets for the three leads by comparing the baseline and current cardiac electrical signals, or may automatically calculate the ST-segment offsets for the cardiac electrical signals and display them in their respective areas, as in user interface 300 of fig. 3. A disadvantage of overlapping the baseline ecg signal and the current ecg signal is that the display pattern is typically relatively small and cluttered, as shown in figure 4. Thus, such displays typically display only a few leads of the cardiac electrical signal waveforms, and do not provide, in conjunction with the digital data display, little or no trend information, e.g., no indication of whether the ST segment excursion is currently becoming larger or smaller.

In the graphical representation method for the real-time ST offset condition of the single lead or the complex lead, the offset value is only displayed longitudinally, but is not displayed in any transverse direction, and in order to more comprehensively represent the ST offset, the ST offset condition is illustrated from the longitudinal direction and the transverse direction.

The embodiment of the application discloses a method for displaying ST segment offset, which is used for visually displaying the ST segment offset.

Referring to fig. 5, a flowchart illustrating a method for displaying ST-segment offsets according to an exemplary embodiment, as shown in fig. 5, includes:

s101: acquiring an electrocardiosignal, and determining a reference value and a current value of an ST segment in the electrocardiosignal relative to a zero potential difference value; wherein the ST segment is located between the QRS complex and the T wave;

s102: displaying a first bending column diagram and a second bending column diagram in a first rectangular coordinate system based on the reference value and the current value;

the left edge of the first longitudinal rectangle is overlapped with the left edge of the first transverse rectangle, and the right edge of the second longitudinal rectangle is overlapped with the right edge of the second transverse rectangle;

Referring to fig. 6, in the embodiment of the present application, a rectangular coordinate system, that is, a first rectangular coordinate system is used to represent the shift amount of the ST segment, and a vertical axis represents a potential value, the first rectangular coordinate system includes two left-right arranged bending column diagrams, that is, a first bending column diagram and a second bending column diagram, and the first bending column diagram and the second bending column diagram respectively represent the current value of the ST segment and the reference value of the ST segment of a certain lead.

The first bending column diagram is a column diagram bent to the right and comprises a first transverse rectangle and a first longitudinal rectangle, and the left edge of the first longitudinal rectangle is overlapped with the left edge of the first transverse rectangle. The second bending column diagram is a column diagram bent leftwards and comprises a second transverse rectangle and a second longitudinal rectangle, and the right edge of the second longitudinal rectangle is overlapped with the right edge of the second transverse rectangle.

The interval between the left edge of the first longitudinal rectangle in the first bending column diagram and the right edge of the second longitudinal rectangle in the second bending column diagram is a first preset value, the interval between the right edge of the first transverse rectangle in the first bending column diagram and the left edge of the second transverse rectangle in the second bending column diagram is a second preset value, and the second preset value is smaller than the first preset value, for example, the second preset value may be 10% of the first preset value. The length ratio between the distance of the left and right edges of the first transverse rectangle (i.e. the length of the first transverse rectangle in the horizontal direction) and the distance of the left and right edges of the second transverse rectangle (i.e. the length of the second transverse rectangle in the horizontal direction) is the ratio of the reference value of the ST segment to the current value of the ST segment. For example, if the ratio of the reference value of the ST segment to the current value of the ST segment is 1:2, the length of the first transverse rectangle in the horizontal direction is 30% of the first preset value, and the length of the first transverse rectangle in the horizontal direction is 60% of the first preset value.

The ordinate corresponding to one of the upper and lower edges of the first longitudinal rectangle in the first bending bar graph is zero, the ordinate corresponding to the other edge is a reference value, the ordinate corresponding to one of the upper and lower edges of the second longitudinal rectangle in the second bending bar graph is a reference value, and the ordinate corresponding to the other edge is a current value. The distance between the other edge of the upper edge and the lower edge of the second longitudinal rectangle and the other edge of the upper edge and the lower edge of the first longitudinal rectangle on the ordinate is the deviation value of the ST segment, and for the second longitudinal rectangle, the ordinate corresponding to one edge of the upper edge and the lower edge is the reference value instead of extending to zero, so that the ST segment deviation value can be displayed more intuitively.

Further, the first bending column diagram and the second bending column diagram may be represented by the same filling color, or may be represented by different filling colors for better intuition, and this embodiment is not particularly limited. For example, in order to highlight the current value of the ST segment, the first bending bar graph adopts a light color system, and the second bending bar graph adopts a dark color system.

In addition, in order to more clearly display the shape of the column, the vertical and horizontal portions of the column have certain thicknesses, and the transverse thickness and the longitudinal thickness (that is, the distance between the upper and lower edges of the transverse rectangle and the distance between the left and right edges of the longitudinal rectangle) may be different, but may also be the same for the sake of the beautiful appearance of the figure, and this embodiment is not particularly limited. For example, the distance between the upper and lower edges of the transverse rectangle and the distance between the left and right edges of the longitudinal rectangle are both 10% of the first preset value.

In order to maintain the extreme shape of the first folded bar graph, the distance between the upper and lower edges of the first transverse rectangle needs to be smaller than the ST-segment reference value. Further, as a preferred embodiment, the present embodiment further includes: calculating an absolute value of a difference value between the reference value and the current value, and determining the distance between the upper edge and the lower edge of the first transverse rectangle and the distance between the upper edge and the lower edge of the second transverse rectangle based on the absolute value; wherein the distance between the upper and lower edges is less than the absolute value. In a specific implementation, in order to maintain the extreme shape of the bent histogram of the second bent histogram, the distance between the upper and lower edges of the first transverse rectangle needs to be smaller than the ST-segment offset value, i.e. the absolute value of the difference between the ST-segment reference value and the current ST-segment value.

In the following description of the present embodiment, the first preset value is regarded as the unit "1", and the ST-stage reference value is V _{ST Standard} Current value of ST segment is V _{ST Current} The second preset value is A% of the first preset value, the first bending bar graph adopts a light color system, the second bending bar graph adopts a dark color system, and the distance between the upper edge and the lower edge of the transverse rectangle is the same as the distance between the left edge and the right edge of the longitudinal rectangle.

If V _{ST Standard} ＝V _{ST Current} And if the second preset value is 5%, the distance between the left and right edges of the first transverse rectangle and the distance between the left and right edges of the second transverse rectangle are both 47.5%, as shown in fig. 7.

If V _{ST Standard} ≠V _{ST Current} Then, the ratio of the distance of the left and right edges of the first transverse rectangle to the unit "1" is:

the ratio of the distance of the left and right edges of the second transverse rectangle to the unit "1" is:

a second preset value of 5%, V _{ST Standard} ＝1.4mv，V _{ST Current} =2.0mV, the ratio of the distance of the left and right edges of the first transverse rectangle to the unit "1" is (1-5%) × 1.4/(1.4 + 2.0) ≈ 39%, and the ratio of the distance of the left and right edges of the second transverse rectangle to the unit "1" is (1-5%) × 2.0/(1.4 + 2.0) ≈ 56%, as shown in fig. 8, according to the above calculation formula.

Specifically, under the condition that the reference value and the current value are both greater than zero, the ordinate corresponding to the lower edge of the first longitudinal rectangle is zero, the ordinate corresponding to the upper edge of the first longitudinal rectangle is the reference value, and the ordinate corresponding to the upper edge of the first transverse rectangle is the reference value. If the reference value is smaller than the current value, the ordinate corresponding to the lower edge of the second vertical rectangle is the reference value, the ordinate corresponding to the upper edge is the current value, and the ordinate corresponding to the upper edge of the second horizontal rectangle is the current value, as shown in fig. 9. If the reference value is equal to the current value, the ordinate corresponding to the lower edge of the second longitudinal rectangle is equal to the ordinate corresponding to the lower edge of the first longitudinal rectangle, the ordinate corresponding to the upper edge of the second longitudinal rectangle is the current value, and the ordinate corresponding to the upper edge of the second transverse rectangle is the current value, as shown in fig. 10. If the reference value is greater than the current value, the ordinate corresponding to the lower edge of the second vertical rectangle is the current value, the ordinate corresponding to the upper edge is the reference value, and the ordinate corresponding to the lower edge of the second horizontal rectangle is the current value, as shown in fig. 11.

And under the condition that the reference value and the current value are both smaller than zero, the ordinate corresponding to the upper edge of the first longitudinal rectangle is zero, the ordinate corresponding to the lower edge of the first longitudinal rectangle is the reference value, and the ordinate corresponding to the lower edge of the first transverse rectangle is the reference value.

The embodiment of the application discloses a method for displaying ST segment offset, which specifically comprises the following steps:

referring to fig. 16, a flowchart illustrating another method for displaying ST-segment offsets according to an exemplary embodiment is shown, as shown in fig. 16, including:

s201: obtaining current values of ST sections in electrocardiosignals of a target lead at a plurality of time points relative to a zero potential difference value, and determining a reference value of the ST sections in the electrocardiosignals of the target lead relative to the zero potential difference value;

s202: displaying the rectangular blocks corresponding to the current values in a second rectangular coordinate system; the horizontal axis of the second rectangular coordinate system corresponds to the current value of the ST segment, the longitudinal axis of the second rectangular coordinate system corresponds to the current value of the ST segment, the length of each rectangular block is a third preset value, the spacing distance between the rectangular blocks at adjacent time points is a fourth preset value, and the longitudinal coordinate of the upper edge of each rectangular block is the corresponding current value;

s203: determining a reference line in the second rectangular coordinate system based on the reference value of the ST segment in the electrocardiosignal of the target lead relative to the zero potential difference value;

s204: constructing an offset rectangle corresponding to each rectangular block based on the datum line and the upper edge of each rectangular block, and marking the offset rectangles in a preset mode; wherein the offset rectangle is used for identifying the offset between the current value and the reference value.

In this embodiment, a second rectangular coordinate system is used to display a trend graph of the ST segment of a certain lead (i.e. the target lead), and the horizontal axis of the second rectangular coordinate system corresponds to time and the vertical axis of the second rectangular coordinate system corresponds to the current value of the ST segment of the target lead. Different rectangular blocks are used for representing current values of the ST segments of the target lead at different time points, the ordinate of the upper edge of each rectangular block is the current value of the ST segment at the corresponding time point, the length of each rectangular block in the horizontal direction is a third preset value, and the height of each rectangular block in the vertical direction is a fixed value which can be set, for example, 0.5cm, or set according to the third preset value, for example, set to be one fifth or one fourth of the third preset value, or set by self-definition according to the preference of a user, which is not specifically limited in this embodiment. The distance between the rectangular blocks corresponding to adjacent time points is a fourth preset value, and the fourth preset value may be equal to or unequal to the third preset value, which is not specifically limited in this embodiment. If the third predetermined value is equal to the fourth predetermined value and is equal to W, the length of the horizontal axis of the second rectangular coordinate system is L, and the current value ST, i.e., the number of rectangular blocks, is N, then W = L/(2N-1), as shown in fig. 17.

The connecting lines in fig. 17 indicate the tendency of the current value of ST, and may be set as solid lines or broken lines (broken lines in fig. 17). The connecting line is from the crossing point of the upper edge of the rectangular block and the right edge as the starting point, the size of the current value of the current ST segment and the current value of the next ST segment is compared, if the next is bigger, the connecting line is drawn from the starting point to the positive direction parallel to the longitudinal axis, if the next is smaller, the connecting line is drawn from the starting point to the negative direction parallel to the longitudinal axis, and after the connecting line is drawn to reach the height of the upper edge of the rectangular block corresponding to the current value of the next ST segment, the connecting line is drawn along the positive direction of the horizontal axis until the left side of the upper edge of the rectangular block corresponding to the current value of the next ST segment is connected.

Further, drawing an offset rectangle representing the ST-segment offset value, firstly determining a reference line representing the ST-segment reference value of the target lead in a second rectangular coordinate system, then constructing an offset rectangle corresponding to each rectangular block based on the reference line and the upper edge of each rectangular block, and marking the offset rectangle in a preset manner, for example, by shading. The larger the area of the offset rectangle is, the larger the time period offset is, and attention should be paid.

As a possible embodiment, one of the upper and lower edges of the offset rectangle has the same abscissa as that of the upper edge of the corresponding rectangular block, and the other edge of the offset rectangle coincides with the reference line, and the left edge of the offset rectangle has the same abscissa as that of the left edge of the corresponding rectangular block. In a specific implementation, as shown in fig. 18, if the current ST-segment value is smaller than the reference ST-segment value, the abscissa of the lower edge of the offset rectangle is the same as the abscissa of the upper edge of the corresponding rectangular block, and is the current ST-segment value, and the upper edge coincides with the reference line, that is, the abscissa of the upper edge is the reference ST-segment value. The abscissa of the left edge of the offset rectangle is the same as the abscissa of the left edge of the corresponding rectangular block.

As another possible embodiment, one of the upper and lower edges of the offset rectangle has the same abscissa as that of the upper edge of the corresponding rectangular block, and the other edge of the offset rectangle coincides with the reference line, and has the same abscissa as that of the right edge of the previous rectangular block of the corresponding rectangular block, and the right edge of the offset rectangle has the same abscissa as that of the right edge of the corresponding rectangular block. In a specific implementation, as shown in fig. 19, if the current ST-segment value is smaller than the reference ST-segment value, the abscissa of the lower edge of the offset rectangle is the same as the abscissa of the upper edge of the corresponding rectangular block, and is the current ST-segment value, and the upper edge coincides with the reference line, that is, the abscissa of the upper edge is the reference ST-segment value. The abscissa of the right edge of the offset rectangle is the same as the abscissa of the right edge of the corresponding rectangular block.

Therefore, in the present embodiment, the current value and the reference value of the ST are subjected to extremization processing, so that the change of the ST is more easily highlighted, and the graphic display of the ST is more meaningful.
