Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. 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.
The invention provides a processing device for a long-range electrocardiogram scatter diagram, which aims to solve the problems that the data volume of the long-range electrocardiogram scatter diagram output by an electrocardiogram detection device in the prior art is large, the area division is not carried out, and the manual analysis difficulty and the working strength are high. As shown in fig. 1, the apparatus includes a region dividing module 110, a boundary acquiring module 120, and an analyzing module 130. The region division module 110 is configured to obtain a target long-range electrocardiograph scattergram, and perform region division on the target long-range electrocardiograph scattergram according to a region division rule corresponding to a theme of the target long-range electrocardiograph scattergram. The boundary obtaining module 120 is configured to obtain boundary points corresponding to the area according to the area attribute of the area and the heartbeat detection data corresponding to the target long-range electrocardiogram scattergram. The analysis module 130 is configured to obtain an area analysis result of the target long-range electrocardiograph scattergram according to the boundary point.
In specific implementation, because the existing long-range electrocardiograph scattergram has a large data amount and is difficult to manually analyze and high in working strength, in this embodiment, after the electrocardiograph detection device acquires heart beat detection data, the region division module 110 makes the heart beat detection data into a scattergram to obtain a target long-range electrocardiograph scattergram to be processed, and performs region division on the target long-range electrocardiograph scattergram according to a region division rule corresponding to a theme of the target long-range electrocardiograph scattergram, which is a problem of the target long-range electrocardiograph scattergram to be analyzed, so as to obtain a preliminary region division result of the target long-range electrocardiograph scattergram. Because the scatter positions and the boundaries of the regions of different long-range electrocardiograph scattergrams are different, in order to better analyze the target long-range electrocardiograph scattergram, the boundary acquisition module 120 further acquires the boundary points corresponding to the regions according to the region attributes obtained after the region division module 110 preliminarily divides the regions and the heartbeat detection data corresponding to the target long-range electrocardiograph scattergram. Finally, the analysis module 130 obtains an area analysis result of the target long-range electrocardiograph scattergram according to the boundary point corresponding to the area obtained by the boundary obtaining module 120.
In a specific embodiment, the device further includes a presetting module for presetting a theme of the long-range electrocardiographic scattergram and a region division rule corresponding to the long-range electrocardiographic scattergram of different themes, and setting a region attribute corresponding to the region. In specific implementation, different long-range electrocardiogram scatter diagrams focus on analyzing different problems, and the long-range electrocardiogram scatter diagrams with different problems have different regional characteristics. In order to reduce the analysis difficulty and the working strength of the long-range electrocardiogram scattergram and improve the analysis efficiency of medical care personnel, the theme of the long-range electrocardiogram scattergram and the region division rule corresponding to the long-range electrocardiogram scattergram with different themes are preset by the preset module, and the region attribute corresponding to each region is set. In a specific embodiment, the presetting module obtains the region division rules corresponding to the long-range electrocardiogram scattergrams of different themes by setting a plurality of themes for a square scattergram region, performing region division for the square scattergram region of each theme and setting the region attribute corresponding to each region, so that the region division module 110 performs preliminary region division for the obtained target long-range electrocardiogram scattergram.
In a specific embodiment, the theme is a set of areas combining a plurality of areas to solve a certain kind of problem, and one theme may include a plurality of areas, and the areas may overlap with each other, but not allow complete overlap. The names of the topics are generally named for solving the problem, such as "room-early", "artifact", but may be arbitrarily named, such as "artifact 4 partitions", and the like, and the number of topics is not limited. The region division rules corresponding to different subjects are usually determined according to known rhythm distribution regions and regions customized by doctors, and the regions are also preset with region attributes, wherein the region attributes comprise shape features, boundary features and heart beat types. Wherein the shape features include an axis type, a circle type, a triangle type, a rectangle type, and a polygon type. The heart beat types include normal (N), ventricular premature (V), supraventricular premature (S), artifact and unknown (a), Bundle Branch Block (BBB), atrial fibrillation and pacing. As shown in fig. 2, the long-range electrocardiograph scattergram with the "ventricular premature editing" theme is divided into four regions, i.e., a ventricular premature beat region, a dominant rhythm region, a post-premature beat region, and a pre-premature beat region, as can be seen from fig. 2.
In a specific embodiment, the boundary features comprise fixed boundary features and unfixed boundary features, the regions with the unfixed boundary features are unfixed, the range of the regions is unfixed, and after the long-range electrocardiogram scatter diagram is obtained, the boundaries of the regions are determined according to the shape features of the regions and heartbeat detection data corresponding to the target long-range electrocardiogram scatter diagram; the region with fixed boundary features has a fixed region range, and as shown in fig. 3, the region distribution diagram corresponds to different shape features and different boundary features, where a solid line is a fixed boundary feature region and a dotted line is an unfixed boundary feature region. In the foregoing steps, it is mentioned that the scatter positions and the area boundaries of the long-range electrocardiographic scattergrams of different patients are different, the long-range electrocardiographic scattergrams of different patients can be automatically adapted by setting the area with unfixed boundary characteristics, and the area with the fixed boundary characteristics is suitable for the area which cannot be automatically searched and the area with a very determined range.
In a specific embodiment, the area dividing module 110 specifically includes a theme obtaining unit and an area dividing unit. The theme acquisition unit is used for acquiring a target long-range electrocardiogram scatter diagram and acquiring a theme of the target long-range electrocardiogram scatter diagram from a preset theme of the long-range electrocardiogram scatter diagram. The region division unit is used for carrying out region division on the target long-range electrocardio scattergram according to a region division rule corresponding to the theme of the target long-range electrocardio scattergram. In specific implementation, after the theme obtaining unit obtains the target long-range electrocardiogram scattergram, a theme can be obtained for the target long-range electrocardiogram scattergram from preset themes of the long-range electrocardiogram scattergram according to a problem to be analyzed. Because the preset module is preset with the region division rules corresponding to the long-range electrocardiogram scattergram with different themes, the region division unit can carry out region division corresponding to the theme on the target long-range electrocardiogram scattergram according to the different themes acquired by the theme acquisition unit, so that a preliminary region analysis result of the long-range electrocardiogram scattergram can be quickly obtained.
In a specific embodiment, the boundary acquiring module 120 includes a first boundary acquiring unit, a second boundary acquiring unit, and a third boundary acquiring unit. The first boundary acquisition unit is used for taking a coordinate point containing the largest number of heart beats in the area as a central point when the shape feature of the area is an axis type, acquiring coordinate points, corresponding to the coordinate points on the axis on two sides of the central point, of heart beats not conforming to the heart beat type of the area from the central point as end points, and acquiring coordinate points, corresponding to the coordinate points on two sides of the end points perpendicular to the axis direction, of heart beats not conforming to the heart beat type of the area from the end points as boundary points of the area. The second boundary acquisition unit is used for sequentially encircling a circular region with increasing radius by taking a coordinate point containing the largest number of heart beats in the region as a circular point when the shape feature of the region is a circular type, and taking the boundary point of the circular region as a boundary point corresponding to the region when all heart beats conforming to the heart beat type of the region are contained in the circular region. The third boundary acquiring unit is configured to, when the shape feature of the region is a triangle type, a rectangle type, or a polygon type, take a coordinate point in the region that includes the largest number of heart beats as a center point, and acquire, from the center point, a coordinate point corresponding to a coordinate point in a vertical direction of each side of the region where a heart beat does not conform to the heart beat type of the region as a boundary point corresponding to the region.
In specific implementation, the boundary obtaining module 120 further includes a feature determining unit, where the feature determining unit is configured to determine whether the shape feature of the region is an axis type, a circular type, a triangular type, a rectangular type, or a polygonal type. When the shape feature of the region is judged to be the axis type, acquiring boundary points of the region through a first boundary unit; when the shape feature of the region is judged to be a circular type, acquiring boundary points of the region through a second boundary acquisition unit; and when the shape characteristic of the region is judged to be a triangle type, a rectangle type or a polygon type, acquiring the boundary point of the region through a third boundary acquisition unit.
In a specific embodiment, the apparatus further comprises a highlighting module and a data processing module. The highlight display module is used for acquiring a region where a target position is located and highlighting the region where the target position is located. The data processing module is used for acquiring the heart beat of the area where the target position is located and carrying out preset operation on the heart beat of the area where the target position is located. In specific implementation, when a user needs to analyze a certain position on the long-range electrocardiogram scattergram, the target position is clicked through a mouse, the highlight display module automatically acquires the coordinates of the target position, and then all the areas are traversed to find the area containing the coordinates of the target position and light the area. The data processing module traverses all heart beats, acquires the heart beat of the area where the target position is located, and performs preset operation on the heart beat of the area where the target position is located, such as displaying an electrocardiogram, modifying the heart beat type, displaying a waveform overlay map and the like, so as to perform more detailed analysis on the area where the target position is located.
The invention also provides a processing method of the processing device for the long-range electrocardiogram scatter diagram, as shown in fig. 4, the method comprises the following steps:
s100, obtaining a target long-range electrocardiogram scatter diagram, and performing region division on the target long-range electrocardiogram scatter diagram according to a region division rule corresponding to the theme of the target long-range electrocardiogram scatter diagram;
s200, acquiring boundary points corresponding to the area according to the area attribute of the area and heartbeat detection data corresponding to the target long-range electrocardiogram scattergram;
s300, obtaining an area analysis result of the target long-range electrocardiogram scatter diagram according to the boundary points.
Because the existing long-range electrocardiogram scatter diagram has a large amount of data, the boundaries between areas are not obvious, and the manual analysis difficulty and the working strength are high. In this embodiment, after the heart beat detection data is acquired by the electrocardiogram detection apparatus, the heart beat detection data is made into a scattergram, and a target long-range electrocardiogram scattergram to be processed is acquired. And then carrying out region division on the target long-range electrocardiogram scattergram according to a region division rule corresponding to the subject of the target long-range electrocardiogram scattergram, which is a problem of the target long-range electrocardiogram scattergram needing to be analyzed, so as to obtain a primary region division result of the target long-range electrocardiogram scattergram. And then acquiring boundary points corresponding to the regions according to the region attributes obtained after the preliminary region division and heart beat detection data corresponding to the target long-range electrocardiogram scattergram. Accurate region analysis results of the target long-range electrocardiogram scattergram with different themes can be obtained according to the obtained boundary points, so that the analysis difficulty and the working strength of the long-range electrocardiogram scattergram are reduced, and the analysis efficiency of medical personnel is improved.
In a specific embodiment, the step S100 further includes:
s0, presetting the theme of the long-range electrocardiogram scattergram and the region division rule corresponding to the long-range electrocardiogram scattergram with different themes, and setting the region attribute corresponding to the region.
In specific implementation, because different long-range electrocardiograph scattergram images focus on analyzing different problems, and the long-range electrocardiograph scattergram images with different problems have different area characteristics, the theme of the long-range electrocardiograph scattergram image and the area division rule corresponding to the long-range electrocardiograph scattergram image with different themes are preset in the embodiment, and the area attribute corresponding to each area is set. In a specific embodiment, a plurality of themes are set in a square scattergram region, region division is performed on the square scattergram region of each theme, and a region attribute corresponding to each region is set, so that region division rules corresponding to long-range electrocardiogram scattergrams of different themes are obtained, and preliminary region division is performed on an obtained target long-range electrocardiogram scattergram in subsequent steps.
In a specific embodiment, the step S100 specifically includes:
s110, obtaining a target long-range electrocardiogram scatter diagram, and obtaining a theme of the target long-range electrocardiogram scatter diagram from a preset theme of the long-range electrocardiogram scatter diagram;
and S120, carrying out region division on the target long-range electrocardiogram scatter diagram according to a region division rule corresponding to the theme of the target long-range electrocardiogram scatter diagram.
In specific implementation, after the target long-range electrocardiogram scattergram is acquired, a theme can be selected for the target long-range electrocardiogram scattergram from preset themes of the long-range electrocardiogram scattergram according to a problem to be analyzed, and since the area division rules corresponding to the long-range electrocardiogram scattergram with different themes are preset, the area division corresponding to the theme can be performed on the target long-range electrocardiogram scattergram according to the selected different themes, so that a preliminary area analysis result of the long-range electrocardiogram scattergram can be quickly obtained.
In a specific embodiment, the step S200 specifically includes:
s210, when the shape feature of the area is an axis type, taking a coordinate point containing the largest quantity of heart beats in the area as a central point, starting to acquire coordinate points, corresponding to coordinate points on the axis on two sides of the central point, of heart beats not conforming to the heart beat type of the area from the central point as end points, and starting to acquire coordinate points, corresponding to coordinate points on two sides of the end points perpendicular to the axis direction, of heart beats not conforming to the heart beat type of the area from the end points as boundary points of the area;

and S230, when the shape feature of the area is a triangle type, a rectangle type or a polygon type, taking a coordinate point containing the largest quantity of heart beats in the area as a central point, and acquiring a coordinate point, corresponding to a coordinate point in the vertical direction of each side of the area, of which the heart beats do not conform to the heart beat type of the area from the central point as a boundary point corresponding to the area.
In specific implementation, when obtaining boundary points corresponding to the region according to the region attribute of the region and heartbeat detection data corresponding to the target long-range electrocardiograph scattergram, it is necessary to first determine whether the shape feature of the region is an axis type, a circular type, a triangular type, a rectangular type, or a polygonal type. When the shape feature of the area is an axis type, taking a coordinate point containing the largest heart beat number in the area as a central point, and judging whether heart beats corresponding to the coordinate points on the axes on two sides of the central point are in accordance with the heart beat type of the area or not from the central point; if so, continuously searching coordinate points, corresponding to the coordinate points, of the heart beat type which does not conform to the area on the axes on the two sides of the central point as end points.
