Description

Technical Field

[0001] The present invention relates to the field of electrocardiogram report analysis, and particularly to a method for interpreting electrocardiogram report levels, a terminal device, and a storage medium. Background Art

[0002] In the field of modern medical diagnosis, electrocardiogram is an extremely crucial examination method, and its importance is self-evident. It not only constitutes the five major conventional pillars of clinical diagnosis together with blood, urine, feces, and imaging examinations, but also plays an irreplaceable cornerstone role in the early detection, condition monitoring, and diagnostic decision-making of cardiovascular diseases. From exploring the occult lesions of chronic ischemic heart disease, to the emergency condition assessment of acute coronary syndrome, and then to the accurate diagnosis of diseases such as myocarditis, pericarditis, pulmonary embolism, and various arrhythmias, electrocardiogram can provide extremely valuable clues.

[0003] Although electrocardiogram has significant advantages such as relatively simple operation, rapid detection process, and low economic cost, the interpretation of its report has always been a difficult problem between doctors and patients. Different from the intuitive numerical changes and arrow indications in examination reports such as blood lipid and blood glucose, electrocardiogram reports are filled with complex professional terms and abstract graphic descriptions, which are as difficult to understand as a heavenly book for ordinary patients. In clinical practice, due to the shortage of medical resources and the busy work of doctors, doctors often cannot spare sufficient time to explain the diagnostic meaning in the electrocardiogram report to each patient in detail. This has created a huge information gap between the actual condition of the disease faced by the patient and the electrocardiogram diagnosis result. This information gap has severely hindered the popularization and application of electrocardiogram monitoring in home health management, resulting in the loss of many precious opportunities for the general public in the early prevention and timely treatment of cardiovascular diseases.

[0004] The prior application patent "A Method for Structured Interpretation of Electrocardiogram Reports, Terminal Device, and Storage Medium" with the publication number of CN117727416A provides new ideas for electrocardiogram report interpretation to a certain extent. Through the popular science interpretation of individual diagnostic terms, it helps patients initially understand the meaning of some professional terms. However, this patent does not deeply consider the internal logical relationship between diagnostic terms and the graded interpretation based on different disease severity levels. This makes it still impossible for patients to accurately judge the urgency of their own condition and the direction of the next medical treatment action when facing an electrocardiogram report. Therefore, there is an urgent need for a more effective method to break through this bottleneck. Summary of the Invention

[0005] To solve the above problems, the present invention proposes a method for interpreting electrocardiogram report levels, a terminal device, and a storage medium.

[0006] The specific solutions are as follows:

[0007] A method for interpreting the grade of an electrocardiogram report, comprising the following steps:

[0008] S1: Construct a dictionary interpretation library, and record in the dictionary interpretation library each diagnostic term corresponding to the diagnostic conclusion, the basic grade representing the urgency and / or potential risk corresponding to each diagnostic term, the grade upgrade conditions corresponding to each diagnostic term, and the upgraded grade;

[0009] S2: Receive the electrocardiogram report and extract the diagnostic conclusion and electrocardiogram measurement values therein;

[0010] S3: Match each diagnostic conclusion with each diagnostic term in the dictionary interpretation library to obtain the diagnostic terms matched by each diagnostic conclusion;

[0011] S4: Determine the grade of each diagnostic conclusion according to the diagnostic terms matched by each diagnostic conclusion and in combination with the dictionary interpretation library;

[0012] S5: Extract the highest grade among the grades of all diagnostic conclusions as the grade of this electrocardiogram report.

[0013] Further, the determination method of the grade of each diagnostic conclusion includes:

[0014] According to the diagnostic term matched by this diagnostic conclusion, look up in the dictionary interpretation library the basic grade, grade upgrade conditions and upgraded grade corresponding to this diagnostic conclusion;

[0015] Combined with the electrocardiogram measurement values in the electrocardiogram report to which this diagnostic conclusion belongs and the diagnostic terms matched by other diagnostic conclusions, judge whether the grade upgrade conditions corresponding to this diagnostic conclusion are satisfied. If so, set the grade of this diagnostic conclusion to the corresponding upgraded grade; otherwise, set the grade of this diagnostic conclusion to the corresponding basic grade.

[0016] Further, the grades include five grades, from low to high are: undefined, normal, positive, high risk, critical.

[0017] Further, it also includes adding reminder information corresponding to the grade on the report in the color corresponding to the grade according to the grade of the electrocardiogram report.

[0018] Further, the color corresponding to the critical grade is red, and the corresponding reminder information is "Your electrocardiogram examination results show critical. Please call 120 immediately!";

[0019] The color corresponding to the high-risk grade is a color of red and yellow alternating, and the corresponding reminder information is "Your electrocardiogram examination results show high risk. Please arrange to see a doctor in the cardiology department of the hospital as soon as possible!";

[0020] When the level is positive, the corresponding color is yellow, and the corresponding reminder message is "Your electrocardiogram examination result shows positive. Please arrange to see a doctor in the cardiology department of the hospital recently!";

[0021] When the level is normal, the corresponding color is green, and the corresponding reminder message is "Your electrocardiogram examination result shows normal. If you have no symptoms related to the cardiovascular system, there is no special treatment for the time being.";

[0022] When the level is undefined, the corresponding color is gray, and the corresponding reminder message is "This electrocardiogram report cannot be interpreted. Please recheck."

[0023] An electrocardiogram report level interpretation terminal device includes 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 in the above embodiments of the present invention are implemented.

[0024] A computer-readable storage medium stores a computer program. When the computer program is executed by a processor, the steps of the method in the above embodiments of the present invention are implemented.

[0025] The present invention adopts the above technical solution. By setting the corresponding basic level and level upgrade conditions for each diagnostic entry and comprehensively considering the correlation between electrocardiogram measurement values and diagnostic entries, a comprehensive and accurate grading interpretation of electrocardiogram reports is realized. Brief Description of the Drawings

[0026] Figure 1 The figure shows a flowchart of the method in Embodiment 1 of the present invention.

[0027] Figure 2 The figure shows a schematic diagram of displaying reminder messages through a small program in this embodiment. Detailed Embodiments

[0028] To further illustrate the embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, mainly used to illustrate the embodiments, and can be used to explain the operation principle of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention.

[0029] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0030] Embodiment 1:

[0031] The embodiment of the present invention provides an electrocardiogram report level interpretation method. As Figure 1 shown, the method includes the following steps:

[0032] S1: Build a dictionary interpretation library, and record in the dictionary interpretation library each diagnostic term corresponding to the diagnostic conclusion, the basic level representing the urgency and / or potential risk corresponding to each diagnostic term, the level upgrade conditions corresponding to each diagnostic term, and the upgraded level.

[0033] In this embodiment, the built dictionary interpretation library is shown in Table 1, and the diagnostic terms therein include the diagnostic terms (keywords) corresponding to all possible electrocardiogram diagnostic conclusions (about 150 are initially set in this embodiment and can be continuously maintained). The level is related to the urgency and / or potential risk. In this embodiment, it is set that the higher the urgency and / or potential risk, the higher the corresponding level. Specifically, five levels are set, namely: undefined (level 0) (corresponding to the situation where the report cannot be interpreted), normal (level 1), positive (level 2), high risk (level 3), critical (level 4). The basic level is the level under the condition of not meeting the level upgrade conditions. The upgraded level is the level under the condition of meeting the level upgrade conditions. The level upgrade conditions need to be set in combination with medical common sense, which will be specifically described below.

[0034] (1) For the common arrhythmia disease of ventricular tachycardia, its initial basic level is set as positive. However, considering that when the heart rate (HR) in the electrocardiogram measurement value of the patient reaches or exceeds 150 bpm, the urgency and potential risk of the condition will increase sharply. Therefore, the level upgrade condition is set as the electrocardiogram measurement value heart rate (HR) being greater than or equal to 150 bpm, and the corresponding upgraded level is set as the "critical" level, meaning that the patient needs to take emergency medical measures immediately.

[0035] (2) For the diagnostic term of atrial fibrillation, due to its relatively high risk in cardiovascular diseases itself, the basic level is determined as high risk. And when the diagnostic term of "ventricular preexcitation" appears at the same time, it indicates that the cardiac electrophysiological condition of the patient further deteriorates, and the superposition of the two diseases may cause more serious arrhythmia or even the risk of cardiac arrest. Therefore, the level upgrade condition is set as the simultaneous appearance of the diagnostic term "ventricular preexcitation", and the corresponding upgraded level is set as the "critical" level, so as to send the most urgent warning signal to the patient and medical staff.

[0036] (3) For the diagnostic term of QT interval prolongation, the initial basic level is high risk. When the electrocardiogram measurement shows that QTc is greater than or equal to 550 ms and at the same time accompanied by the diagnostic result of "ventricular tachycardia", it indicates that the cardiac repolarization process of the patient has a serious abnormality and is combined with tachyarrhythmia, and the condition is extremely critical. Therefore, the level upgrade condition is set as the electrocardiogram measurement value QTc being greater than or equal to 550 ms and the diagnostic term "ventricular tachycardia" appearing at the same time, and the corresponding upgraded level is set as the "critical" level to ensure that the patient can obtain corresponding emergency treatment in time.

[0037] Table 1

[0038]

[0039] S2: Receive the electrocardiogram report and extract the diagnosis conclusion and electrocardiogram measurement values from it.

[0040] The electrocardiogram report is a report with a diagnosis result recorded after being diagnosed by a doctor. From this electrocardiogram report, electrocardiogram measurement values (such as numerical values in the form of key-value pairs {"HR": 60, "PR": 154, "QRS": 96, "QT": 420}) and diagnosis conclusions (such as {"sinus rhythm", "sinus arrhythmia"}) can be extracted.

[0041] S3: Match each diagnosis conclusion with each diagnosis entry in the entry interpretation library to obtain the diagnosis entries matched by each diagnosis conclusion.

[0042] The matching of the diagnosis conclusion and the diagnosis entry can be carried out using existing algorithms, such as similarity algorithms, regular expression rules, etc., without limitation.

[0043] S4: Determine the level of each diagnosis conclusion based on the diagnosis entries matched by each diagnosis conclusion and in combination with the entry interpretation library.

[0044] In this embodiment, the method for determining the level of each diagnosis conclusion is as follows: According to the diagnosis entry matched by the diagnosis conclusion, look up the basic level, level upgrade condition, and upgraded level corresponding to the diagnosis conclusion in the entry interpretation library. Combine the electrocardiogram measurement values in the electrocardiogram report to which the diagnosis conclusion belongs and the diagnosis entries matched by other diagnosis conclusions to determine whether the level upgrade condition corresponding to the diagnosis conclusion is met. If so, set the level of the diagnosis conclusion to the corresponding upgraded level; otherwise, set the level of the diagnosis conclusion to the corresponding basic level.

[0045] S5: Extract the highest level among the levels of all diagnosis conclusions as the level of this electrocardiogram report.

[0046] Furthermore, in order to present the report grading result to the user more intuitively and clearly, this embodiment also adopts a combination of distinct color markings and simple and clear guiding operations to generate a corresponding prompt box. The color (i.e., the background color) of the prompt box corresponding to each level is the color corresponding to the level, and the content is the reminder information corresponding to the level, as shown in Table 2.

[0047] When the electrocardiogram report is determined to be in the critical level, the system will display "Your electrocardiogram examination result shows a critical condition. Please call 120 immediately!" to the user in eye-catching red, and at the same time strongly recommend that the user immediately call the 120 emergency call so as to obtain emergency medical assistance quickly.

[0048] For high-risk ECG reports, the system will display "Your ECG test results show high risk, please arrange to see the hospital's cardiology department as soon as possible!" in red and yellow colors, and guide users to obtain professional medical advice and further diagnosis and treatment as soon as possible by consulting experts online or going directly to the hospital's cardiology department.

[0049] When the report is graded as positive, the system will display "Your electrocardiogram result is positive. Please arrange to see the cardiology department of the hospital in the near future!" in yellow, reminding users to arrange time to go to the cardiology department of the hospital for an outpatient examination in the near future so as to understand their health status in time and take appropriate measures.

[0050] For normal level ECG reports, the system will display in green "Your ECG test results are normal. If there are no cardiovascular system-related symptoms, no special treatment is required." This allows users to rest assured that their ECG results are normal without having to worry too much.

[0051] When the report is judged as undefined, the system will display "This ECG report cannot be interpreted, please recheck." in gray, prompting the user that there may be some problems with the current ECG report and it needs to be rechecked to ensure an accurate diagnosis result.

[0053]

[0054] Through this intuitive visual presentation and clear operation instructions, this embodiment can help users quickly and accurately understand the status of the electrocardiogram and take appropriate actions decisively, thereby greatly improving the efficiency and quality of cardiovascular disease prevention and control and providing strong protection for the health of patients.

[0055] The above method can be implemented by directly setting a reminder information area on the report to be generated when generating a paper report, and adding the generated prompt box to the reminder information area before generating the report.

[0056] In other embodiments, the ECG report can be uploaded through the patient terminal. When the received ECG report is uploaded to the patient device (APP or mini program), the generated prompt box is sent to the patient device for display. In addition, when the level corresponding to the prompt box is positive, high risk, or critical, in addition to the prompt box, a guide operation button is added to the interface of the actual prompt box. After the guide operation button is selected, the operation contained in the prompt information corresponding to the level is directly performed to facilitate the user. Figure 2 Shown is the result of displaying reminder information through the applet.
