(2) Under the influence of the size of the display, even if the image can be completely displayed, the situation that the details cannot be displayed due to too many overlapping areas of waveform points can also occur in the whole waveform.

Detailed Description
To further illustrate the various embodiments, the invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures.
The invention will now be further described with reference to the accompanying drawings and detailed description.
The first embodiment is as follows:
an embodiment of the present invention provides an electrocardiogram waveform amplification method, as shown in fig. 1, the method includes the following steps:
s1: obtaining DPI (Dots Per Inch) of the display module and the number dot of pixel points contained in the horizontal axis direction in the area of the display module for displaying the electrocardiogram data.
The display module may be a commonly used display device, such as a monitor. The area of the display module for displaying the electrocardiographic data is determined according to the actual program application, such as the entire screen of the display as the area for displaying the electrocardiographic data or a part of the screen as the area for displaying the electrocardiographic data. The horizontal axis direction in the display module corresponds to the horizontal axis direction in the electrocardiogram data to be displayed.
S2: when the electrocardiogram data are loaded to be displayed on the display module, a first resampling rate f1 of the electrocardiogram data is calculated according to the DPI of the display module, the number dot of pixels and the sampling rate fs of the electrocardiogram data, the electrocardiogram data are resampled for the first time based on the first resampling rate f1 to obtain the electrocardiogram data to be displayed, and the electrocardiogram data to be displayed are sent to the display module to be displayed.
The loaded electrocardiogram data is the original electrocardiogram data obtained by the electrocardiogram acquisition equipment. The loading of the electrocardiogram data may be performed by receiving and storing the electrocardiogram data in the storage module in advance, loading the electrocardiogram data from the storage module, or directly loading the electrocardiogram data in an uploading manner, which is not limited herein.
In the embodiment, 1:1 conversion between sampling points in the electrocardiogram data and pixel points in the display module is required, that is, one sampling point corresponds to one pixel point, so that a first resampling ratio f1 required for displaying the electrocardiogram data on the display module can be calculated according to the DPI of the display module, the number dot of the pixel points and the sampling rate fs of the electrocardiogram data. The resampling algorithm may be implemented by using an existing algorithm, which is not limited herein, and in this embodiment, the resampling algorithm is represented as p ═ f1(a, dot, dpi, fs), where p represents a set of sample points in the electrocardiographic data after resampling, and a represents a set of sample points in the electrocardiographic data before resampling.
Assuming that the sampling rate fs of electrocardiographic data is 1000 and dpi is 96dot/inc, the length len of the display area actually required for completely outputting an electrocardiographic waveform image of one lead for 10 seconds is:
len＝10*fs/dpi
calculations can yield len 104.2Inch (feet) ≈ 2.65m, which in reality is not substantially fitted with displays of this size. To accommodate a conventional display, the waveform may be presented on a small-sized display after calculation of the first resampling ratio f 1. Assuming that the area of the display module is wa 1000 × 800, the first resampling ratio f1 is preferably implemented by setting fs to 100 (width of wa 1000/10 seconds) to screen points (p ═ f1(a, dot, dpi,100)), that is, 1000 pixels can display complete 10s of data, which means that the waveform is lost at 900 points per second under the current fs.
S3: and based on the magnification ratio s, calculating a second resampling ratio f2 of the electrocardiogram data according to the DPI of the display module, the pixel number dot of the s times and the sampling rate fs of the electrocardiogram data, and performing second resampling on the electrocardiogram data based on the second resampling ratio f2 to obtain amplified electrocardiogram data.
The magnification ratio can be set by the user, and the setting mode can be selected by clicking a pull-down menu on the display module through data, or can be input through a keyboard, which is not limited herein.
The second resampling rate f2 calculated by the pixel number dot of s times is s times greater (i.e., the sampling point is increased by s times) for the sampled data compared with the second resampling rate f2 calculated by the pixel number dot, so that the number of sampling points in the electrocardiogram data to be displayed obtained by the second resampling is increased by s times, and the details are less lost.
S4: and according to the coordinate position of the mouse in the display module and the range of the amplification area to be displayed, intercepting the amplified electrocardiogram data in the corresponding range from the amplified electrocardiogram data and sending the amplified electrocardiogram data to the display module for displaying.
The range of the intercepted amplified electrocardiographic data is: and the enlarged electrocardiogram data in the enlarged region range by taking the corresponding data of the electrocardiogram data to be displayed in the display module corresponding to the coordinate position of the mouse as the center.
Taking the magnification ratio s as an example, as shown in fig. 2, the virtual display region pixels corresponding to the enlarged electrocardiographic data are vwr ═ 1000 × 2 × 800 × 2, the second resampling ratio f2 is calculated at 2 × dot, and the enlarged electrocardiographic data are obtained, and when the enlarged electrocardiographic data are clipped, if the enlarged region range is mp ═ x × y, the virtual display region pixels corresponding to the clipped data in the enlarged electrocardiographic data corresponding to the enlarged region range are vmp ═ x × 2 × y.
In the embodiment, when the enlarged electrocardiogram data is sent to the display module for displaying, the enlarged electrocardiogram data to be displayed is displayed by taking the coordinate position of the mouse as the center.
Further, in order to increase the processing speed, the embodiment further includes saving the enlarged electrocardiogram data obtained by the second resampling as a bitmap, and performing truncation in the bitmap at the time of the truncation at step S4.
As shown in fig. 3, the original waveform and the enlarged display result based on the vector diagram in the conventional method are shown, and it can be seen that there is no obvious difference between the waveform before and after enlargement, and only the size of the diagram is different.
Fig. 4 shows the original waveform and the enlarged display result based on the vector diagram in the method of the present embodiment, from which it can be seen that the waveform after enlargement is not only the change of the size of the diagram before enlargement, but also the resolution is increased more, the details are more, and the use of the staff can be better assisted.
