Example two:
fig. 2 shows a schematic flow chart of an implementation of a data measurement method of an electrocardiographic waveform provided in another embodiment of the present application, which is detailed as follows:
step S21, acquiring a preset condition, and initializing the preset area according to the preset condition, where the preset condition includes size information of the preset area and parameter information of the relevant data.
In the step, the configuration file is read to obtain a preset condition, and the floating window is initialized according to the preset condition. The preset conditions comprise the size of a floating window set by a user and parameter information of an electrocardiographic waveform. The preset conditions may be stored in a configuration file, for example, the preset conditions include:
a) floating window size (horizontal size, vertical size in pixels);
b) when the suspension window tracks the movement of the test point, the deviation of the center point of the window relative to the test point (the deviation in the horizontal direction and the vertical direction takes a pixel as a unit);
c) QRS display parameters (mainly including amplitude (mv), P-wave width (ms), PR interval width (ms), QRS interval width (ms), qt (qtc) interval width (ms), RR interval width, ST value) (the mid-band of the electrocardiogram includes: p-wave, PR interval, QRS complex, J-point, ST segment, T-wave, U-wave, and QT interval);
d) QRS waveform display number.
Step S22, acquiring the electrocardiographic waveform of the user, and detecting the position of the test point; judging whether the position of the test point is located in the area of the electrocardiographic waveform in real time, and if the test point is located in the area of the electrocardiographic waveform, calculating the offset of the test point relative to the starting point of the preset electrocardiographic waveform interval; and determining whether the test point is positioned in the preset electrocardiographic waveform interval or not according to the offset.
The display interface of the electrocardiographic waveform comprises an electrocardiographic waveform area and other display areas except the electrocardiographic waveform, so that the position of the test point is firstly detected for the obtained electrocardiographic waveform of the user, and then whether the position of the test point is located in the waveform diagram area of the electrocardiographic waveform is judged in real time. If the test point is in the area of the electrocardiographic waveform, calculating the offset of the current test point relative to the starting point of the electrocardiographic waveform in real time according to the walking speed of the current electrocardiographic waveform, wherein the calculation formula is as follows:
and judging whether the current test point position is located in a section (namely the preset electrocardiographic waveform section) from the P wave starting point of the QRS waveform to the T wave end point of the QRS waveform according to the calculated offset, and if the test point position is located in the section, indicating that the current test point is located in the preset electrocardiographic waveform section.
Step S23, when the test point is located in the preset electrocardiographic waveform interval, obtaining the size of the preset area, and calculating the gain and the walking speed of the electrocardiographic waveform of the user according to the size; and displaying the waveform diagram amplified in the preset electrocardiographic waveform interval in the preset area according to the gain and the walking speed.
In this step, when the measurement point is located in the preset electrocardiographic waveform interval, preset conditions such as the size of the preset region (such as a floating window) are obtained, the travel speed and the gain of the QRS wave are calculated according to the conditions such as the obtained size, finally, the amplification factor of the QRS wave is determined according to the calculated travel speed and the calculated gain, and the waveform diagram of the amplified preset electrocardiographic waveform region is displayed in the preset region.
The formula for calculating the walking speed and the gain is as follows:
and step S24, drawing a measuring line in the amplified waveform diagram, and acquiring the relevant data of the electrocardiographic waveform according to the measuring line, wherein the measuring line comprises a horizontal measuring line or/and a vertical measuring line.
Specifically, a horizontal measurement line or/and a vertical measurement line are drawn in the amplified oscillogram according to the position of the feature point obtained by analyzing the preset algorithm, wherein the horizontal measurement line is used for identifying the amplitude, the base line and the position of each feature point of the QRS waveform, and a user can conveniently modify the measurement parameter information of the QRS waveform by dragging the measurement line after a suspended window is locked subsequently. The horizontal (longitudinal) measurement line is intelligently plotted at the peak or baseline position of the QRS waveform (e.g., measurement line a in fig. 3), and the vertical (lateral) measurement line is intelligently plotted at various feature points (e.g., Q-wave start point or S-wave end point in fig. 3). And acquiring related data of the QRS waves according to the position of the measuring line, wherein the type information of the data can be acquired according to the preset condition. The display of the measured correlation data as a position can be set by the user.
Optionally, when the preset area is the floating window, the user may control the display and the hiding of the floating window through a shortcut key. When the user hides the floating window through the shortcut key, the amplified QRS waveform is no longer displayed. Further, if the position of the test point does not satisfy the condition in step S22, the floating window is automatically hidden.
Optionally, the embodiment provided by the present application may further determine whether to lock the floating window according to a selection of the user, and this step may also be implemented by a shortcut key set by the user. When the user locks the floating window, if the test point is outside the floating window area and moves in the preset electrocardiographic waveform area, locking the current displayed QRS waveform in the floating window. If the test point enters the suspension window area, the position of the vertical (transverse) measurement line or the horizontal (longitudinal) measurement line can be dragged through the movement of the test point, and the displayed QRS waveform measurement parameter information is updated in real time. Further, when the user unlocks the floating window or switches to other pages, if the parameter information in the QRS waveform is modified, prompt information is sent to the user to inquire whether the user stores the QRS measurement information before and after modification.
Optionally, when the floating window is not frozen, the floating window updates the QRS waveform and parameter display following the movement of the test point position. The floating window display area is limited to the electrocardiographic waveform area. The user may adjust the relative positions of the floating window and the test point by modifying the attribute values of the relevant fields of the configuration file storing the preset conditions in step S21. When the relative position is set, and in the process of following and displaying the test point, if the display area required by the floating window exceeds the waveform area, the rearrangement is automatically carried out.
Optionally, when data at different positions in the amplified oscillogram needs to be measured, the method for measuring data of an electrocardiographic waveform further includes:
step S25, locking the preset area; and if the test point is positioned in the locked preset area, acquiring relevant data of a required position on the electrocardiographic waveform according to the movement condition of the test point.
Specifically, after a suspension window (a preset area) for displaying the amplified oscillogram is locked, the QRS waveform is also locked, at this time, the position of the test point is detected, and if the test point moves to the locked suspension window area and is located on the horizontal (longitudinal) measurement line, the test point is dragged to further drag the vertical (transverse) measurement line to move to a required position, and the related data at the position corresponding to the QRS wave after the measurement line moves is detected. Also, when the test point is located on a vertical (lateral) measurement line, the position of the measurement line can be changed by the above method as well, and the relevant data at the desired position can be obtained.
Further, if the floating window is frozen, the vertical (lateral) measuring line is frozen, the horizontal (longitudinal) measuring line is activated, and the frozen measuring line is fixed in position. The state in which both are frozen or activated can be switched by a preset operation such as pressing a designated key. Fig. 3 is a schematic diagram in which the vertical (lateral) measuring lines are activated, the measuring lines in the activated state being shown in solid lines and the locked measuring lines being shown in dashed lines. Fig. 4 is a schematic diagram in which the horizontal (longitudinal) measurement line is activated.
The following describes the adjustment process and adjustment range of the measurement line position:
FIG. 3 is a schematic diagram showing the process of activating the transverse measurement line to adjust the position, the adjustment process being as follows:
when the test point is moved, the position of the test point closest to the measurement line of the transverse feature point is detected, the position of the feature point is updated in real time according to the current position of the test point, meanwhile, related data of a QRS wave are calculated according to a preset algorithm, and then the calculated data are displayed. The moving range of the measuring line at the characteristic point in different areas is as follows:
p1 point measurement line: the measurement line of the starting point of the P wave is adjusted within the range from the starting point of the QRS wave to the end point of the P wave.
P2 point measurement line: the range of the P wave end point measuring line is between the P wave starting point and the Q point measuring line.
Measurement line of point Q: the range is from the P wave end point to the S point measuring line.
S point measurement line: the range is from the Q point measuring line to the T wave end point measuring line.
T point measurement line: the range is from the measurement line of the S point to the end point of the QRS waveform.
Fig. 4 shows the adjustment process of the measurement line position when the longitudinal measurement line is activated, as follows:
when the test point is moved, the suspension window judges the position of the test point, which is closest to the longitudinal measurement line, then the position of the longitudinal measurement line is updated in real time according to the current position of the test point, and measurement parameter information of the QRS wave is calculated according to a preset algorithm and displayed. The moving range of the measuring line at the characteristic point in different areas is as follows:
a, measuring line: the QRS waveform amplitude measurement line ranges from the height of the QRS waveform peak to the baseline measurement line (B).
B, measuring line: the QRS waveform baseline measurement line ranges from the measurement line of the QRS waveform peak A to the waveform bottom.
The QRS waveform in a certain area can be automatically amplified and displayed according to the position of the test point, so that the complicated process that a user needs to manually amplify every time is avoided; in addition, a measuring line is drawn in the amplified oscillogram, so that related data of the electrocardiographic waveform are obtained according to the measuring line, the process is quick, a doctor does not need to manually amplify the oscillogram and then search and calculate data of related positions, and meanwhile, the user can conveniently check the QRS waveform of the lead and measure the related data.
