Description

Technical Field

[0001] The present invention relates to the field of electrocardiogram diagnosis, and in particular to a method for reversely confirming a cardiac beat diagnosis result, a terminal device and a storage medium. Background Art

[0002] In the daily dynamic electrocardiogram diagnosis and analysis process, a 24-hour dynamic electrocardiogram has about 80,000 to 140,000 heartbeats. The diagnosing doctor needs to edit and confirm the accuracy of the types and positions of such a large number of heartbeats, and then issue the number of arrhythmia heartbeats and diagnostic conclusions of this dynamic electrocardiogram. It is definitely impractical to confirm the accuracy of each heartbeat, so a function that can batch confirm the accuracy of heartbeat information and qualitative dynamic electrocardiogram arrhythmia is needed to improve the doctor's work efficiency. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a method for reverse confirmation of heartbeat diagnosis results, a terminal device and a storage medium.

[0004] The specific plan is as follows: A method for reverse confirmation of heartbeat diagnosis results comprises the following steps: S1: receiving electrocardiogram data including a heartbeat type diagnosis result, and generating a corresponding heartbeat sequence; S2: group the heartbeat sequences according to fixed intervals, and calculate the average heart rate, number of heartbeat types and heart rate variability corresponding to each group of heartbeats; S3: Calculate the distance between two adjacent groups of heartbeats according to the average heart rate, number of heartbeat types and heart rate variability of each group of heartbeats; S4: determining a rhythm jump-out point of the heartbeat sequence based on two adjacent groups of heartbeats whose distance is greater than a distance threshold; S5: After segmenting the heartbeat sequence by rhythm jump-out points, different Lorenz scatter plots are used to display the heartbeats corresponding to different segments; S6: Determine whether the corresponding heartbeat type is accurately diagnosed based on each displayed Lorenz scatter plot.

[0005] Furthermore, the fixed interval is 10 heart beats.

[0006] Furthermore, the calculation formula for the distance between two adjacent groups of heartbeats is:

[0007] in, represents the distance between the nth group of heart beats and the n+1th group of heart beats, and Respectively represent the average heart rate of the nth group of heart beats and the n+1th group of heart beats, and They represent the number of heartbeat types contained in the nth heartbeat group and the n+1th heartbeat group, respectively. and They represent the heart rate variability of the nth group of heart beats and the n+1th group of heart beats respectively.

[0008] Further, when determining the rhythm jump-out point of the heartbeat sequence based on two adjacent groups of heartbeats whose distance is greater than a distance threshold, when the distance between the two adjacent groups of heartbeats is greater than the distance threshold, the segmentation point of the two adjacent groups of heartbeats is used as the rhythm jump-out point.

[0009] A terminal device for reverse confirmation of cardiac diagnosis results comprises a processor, a memory and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the method described above in the embodiment of the present invention are implemented.

[0010] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the method described above in an embodiment of the present invention are implemented.

[0011] The present invention adopts the above technical solution to display heartbeats of different rhythms in the form of different Lorenz scatter plots, so that doctors can quickly confirm the accuracy of the pre-diagnosis results to avoid missed diagnosis and misdiagnosis.

[0017] To further illustrate various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in this field should be able to understand other possible implementations and advantages of the present invention.

[0018] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0019] Embodiment 1: The embodiment of the present invention provides a method for reverse confirmation of heartbeat diagnosis results, which is based on the doctor having completed basic diagnosis work on a piece of electrocardiogram data (i.e., having completed editing of the heartbeat type of each heartbeat), such as Figure 1 As shown, the method comprises the following steps: S1: Receive electrocardiogram data including heartbeat type diagnosis results and generate corresponding heartbeat sequences.

[0020] The order of each heartbeat in the heartbeat sequence is sorted according to the order of each heartbeat corresponding to the electrocardiogram, and the heartbeat data can be scanned starting from the beginning of the electrocardiogram.

[0021] The heart beat types include normal and various arrhythmias, such as atrial fibrillation, atrial flutter, etc.

[0022] S2: The heartbeat sequences are grouped at fixed intervals and the average heart rate (HR), number of beat types (BN) and heart rate variability (RMSSD) corresponding to each group of heartbeats are calculated.

[0023] The fixed interval set in this embodiment is 10 heart beats, that is, 10 heart beats form a group.

[0024] The heartbeat of the nth group is recorded as X n =[HR n ,BN n ,RMSSD n ].

[0025] S3: Calculate the distance between two adjacent groups of heartbeats based on the average heart rate, number of heartbeat types and heart rate variability of each group of heartbeats.

[0026] The calculation formula of the distance between two adjacent groups of heartbeats in this embodiment is:

[0027] in, represents the distance between the nth group of heart beats and the n+1th group of heart beats, and Respectively represent the average heart rate of the nth group of heart beats and the n+1th group of heart beats, and They represent the number of heartbeat types contained in the nth heartbeat group and the n+1th heartbeat group, respectively. and They represent the heart rate variability of the nth group of heart beats and the n+1th group of heart beats respectively.

[0028] S4: Determine a rhythm jump-out point of the heartbeat sequence based on two adjacent groups of heartbeats whose distance is greater than a distance threshold.

[0029] There are about 100,000 heartbeats in a 24-hour dynamic electrocardiogram. The heartbeat information (including arrhythmia type, interval, amplitude, etc.) in a continuous time period is constantly changing, but this change will present a regular repetitive cycle, which we call rhythm. Heart rhythm refers to a series of electrical activities of the atria and ventricles caused by the impulses sent by the sinoatrial node through the atrioventricular node, the atrioventricular bundle, and finally through the left and right bundle branches and transmitted to the Purkinje fibers. It is reflected in the electrocardiogram that the intervals within a period of time may be small, large, absolutely irregular, or may have regular alternations of fast and slow, etc.

[0030] When the collected heartbeat changes no longer conform to the previous rules, the subsequent heartbeats may start another regular repetitive cycle, that is, forming a new rhythm. The time point when the previous rhythm ended is called the rhythm jump-out point.

[0031] In this embodiment, when the rhythm exit point of the heartbeat sequence is determined based on two adjacent groups of heartbeats whose distance is greater than the distance threshold, when the distance between the two adjacent groups of heartbeats is greater than the distance threshold, the division point of the two adjacent groups of heartbeats is used as the rhythm exit point, that is, when the distance between the nth group of heartbeats and the n+1th group of heartbeats is greater than the distance threshold, the division point between the nth group of heartbeats and the n+1th group of heartbeats is used as the rhythm exit point.

[0032] The cardiac sequence may contain multiple rhythm jump points, and all rhythm jump points need to be found.

[0033] The size of the distance threshold can be set by those skilled in the art based on experimental data and is not limited here.

[0034] S5: After segmenting the heartbeat sequence by rhythm jump-out points, different Lorenz scatter plots are used to display the heartbeats corresponding to different segments.

[0035] When M rhythm jump-out points are found, the heart beat sequence is divided into M+1 segments.

[0036] The Lorenz scatter plot is a two-dimensional coordinate system, in which the horizontal axis represents the heartbeat interval and the vertical axis represents the compensatory interval of the heartbeat. The interval refers to the time interval between the current heartbeat and the previous heartbeat. The compensatory interval refers to the process of premature beats, in which the premature contraction of premature beats causes the heart rhythm to be reorganized, resulting in a compensatory gap.

[0037] S6: Determine whether the corresponding heartbeat type is accurately diagnosed based on each displayed Lorenz scatter plot.

[0038] Since each heartbeat corresponds to the same rhythm, when it is displayed through a Lorenz scatter plot, the type of heartbeat can be better judged based on the display result, and then the judgment result based on the Lorenz scatter plot can be compared with the diagnosis result to determine whether the diagnosis result is correct.

[0039] The embodiment of the present invention presents the characteristics of Lorenz scatter plots with different distribution forms according to different arrhythmia heart rates, such as Figure 2-5 The Lorenz scatter plots shown correspond to atrial fibrillation, atrial flutter, premature ventricular bigeminy, and ventricular parallel rhythm. Displaying heart beats of different rhythms in the form of different Lorenz scatter plots can help doctors quickly confirm the accuracy of the pre-diagnosis results to avoid missed diagnosis and misdiagnosis.

[0040] Embodiment 2: The present invention also provides a terminal device for reverse confirmation of cardiac diagnosis results, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps in the above-mentioned method embodiment of the first embodiment of the present invention when executing the computer program.

[0041] Further, as an executable solution, the terminal device for reverse confirmation of the heartbeat diagnosis result can be a computing device such as a desktop computer, a notebook, a PDA, and a cloud server. The terminal device for reverse confirmation of the heartbeat diagnosis result can include, but is not limited to, a processor and a memory. Those skilled in the art can understand that the composition structure of the terminal device for reverse confirmation of the heartbeat diagnosis result is only an example of the terminal device for reverse confirmation of the heartbeat diagnosis result, and does not constitute a limitation on the terminal device for reverse confirmation of the heartbeat diagnosis result. It can include more or less components than the above, or combine certain components, or different components. For example, the terminal device for reverse confirmation of the heartbeat diagnosis result can also include input and output devices, network access devices, buses, etc., and the embodiment of the present invention does not limit this.

[0043] The memory can be used to store the computer program and / or module, and the processor realizes various functions of the terminal device for reverse confirmation of cardiac diagnosis results by running or executing the computer program and / or module stored in the memory and calling the data stored in the memory. The memory can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system and an application required for at least one function; the data storage area can store data created according to the use of the mobile phone, etc. In addition, the memory can include a high-speed random access memory, and can also include a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0044] The present invention also provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the above method in the embodiment of the present invention are implemented.

[0045] If the module / unit integrated in the terminal device for reverse confirmation of the heartbeat diagnosis result is implemented in the form of a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the present invention implements all or part of the processes in the above-mentioned embodiment method, and can also be completed by instructing the relevant hardware through a computer program.
