[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] In the present application embodiment, a method for evaluating the immediate therapeutic effect of cardiac rehabilitation is provided. Figure 1 , Figure 1 1 is a flow chart of a method for evaluating the immediate therapeutic effect of cardiac rehabilitation in an embodiment; the method for evaluating the immediate therapeutic effect of cardiac rehabilitation includes steps S1 to S5.

[0057] Step S1, before treatment, performing a load exercise test on the subject, obtaining first electrocardiogram data, and determining an average heart rate AHR1 of the first exercise load segment;

[0058] Step S2, after the treatment, performing a load exercise test on the subject, obtaining second ECG data, and determining an average heart rate AHR2 in the second exercise load segment;

[0059] In some embodiments, performing a load exercise test on the subject specifically includes:

[0060] The subject is maintained in a static state for a first period of time, then in a warm-up state for a second period of time, and finally in a loaded exercise state for a third period of time.

[0061] In some embodiments, the subject is maintained in a static state for a first period of time, then in a warm-up state for a second period of time, and finally in a high-load exercise for a third period of time, comprising:

[0062] Determine the load under high-load exercise according to the examinee's exercise heart rate;

[0063] Wherein, safe heart rate = (200-age) * 85%, the minimum heart rate is 90 bpm, and the load of the subject under high-load exercise makes the subject's exercise heart rate under high-load exercise higher than the minimum heart rate and does not exceed the safe heart rate;

[0064] The load in the warm-up state is half of the load in the high-load exercise.

[0065] Specifically, the first exercise load segment and the second exercise load segment refer to the third period of high-load exercise in the two load exercise tests before and after the treatment, respectively. The treatment can be any cardiac rehabilitation treatment. In this application, transthoracic ultrasound treatment is taken as an example.

[0066] In some embodiments, in a load exercise test before and after treatment, the intensity, load (light to medium) and duration of the two exercises need to be exactly the same, so as to avoid the dependence of biological work, metabolic equivalent calculations, etc. on expensive hardware and software structure platform support, as well as complex problems such as complex measurement and difficult judgment.

[0067] In some implementations, when calculating the average heart rate, the average heart rate during the period of the stable exercise phase may be selected.

[0068] In some embodiments, the exercise load is set as:

[0069] The load, cadence and exercise time of the two load exercises were determined according to the subject's gender, height and heart rate response to the load exercise.

[0070] The subject exercises on a treadmill. There is a load setting device on the treadmill, which can be set from 0W (no load) to 300W, and the wattage can be preset. Under high-load exercise, it is generally about 120W for men and about 100W for women. It can be set according to the experience of the doctor who can examine: men, tall people, and those with good sports foundation can adjust it higher, and vice versa; the general adjustment range is set at 80W to 120W, and the load is halved in the warm-up state; another factor of load is the pedaling frequency, which is guided by an electronic metronome and is fixed at 60bpm, with one pedaling for every 2 beats. The pedaling frequency remains unchanged in the warm-up state and high-load exercise.

[0071] For example, a 50-year-old male with no obvious clinical background of organic heart disease, 1.76 meters tall, and a history of playing table tennis, has the following load settings:

[0072] Maintain the static state for the first time, at this time, 0 load;

[0073] Continue the warm-up state for the second time, then walk for 1 minute, load: pedaling load 60W, pedaling frequency 60bpm (30 laps);

[0074] The third period of high-load exercise lasts for 5 minutes, with a load of 120W pedaling load and a pedaling frequency of 60bpm (30 laps).

[0075] Once the setting is determined, it cannot be changed. That is, the first load exercise test and the second load exercise test should be consistent. Whether the load setting is appropriate is mainly determined by whether the heart rate is too slow or too fast during the whole exercise process:

[0076] If the fastest heart rate during exercise is less than 90bpm, it indicates that the preset load is insufficient;

[0077] If the heart rate tends to exceed the safe heart rate, it is considered as overload;

[0078] Safe heart rate = (200-age)*85% In this case, it is 129bpm.

[0079] If there is a trend of too slow or too fast heart rate, terminate the test, arrange another time, and reset the load for inspection.

[0080] In some embodiments, ECG, blood pressure, and blood oxygen monitoring are performed throughout the entire process to prevent the patient from experiencing sudden abnormal cardiac events (such as exercise-induced hypotension, etc.); holographic ECG data is recorded, and the ECG data is used to derive the increase in myocardial load bearing capacity for comparison before and after treatment, and the comparison results are automatically derived for reference by clinical physicians for diagnosis and efficacy evaluation.

[0081] In some embodiments, the process of performing stress exercise testing on the subject before and after treatment can be described as follows. Figure 2 The diagram shows the process of the subject undergoing load exercise test.

[0082] Step S3, determining a heart rate reserve change value according to the average heart rate AHR1 of the first exercise load segment and the average heart rate AHR2 of the second exercise load segment;

[0083] In some embodiments, in determining the heart rate reserve change value based on the average heart rate AHR1 of the first exercise load segment and the average heart rate AHR2 of the second exercise load segment, the difference between the average heart rate AHR1 of the first exercise load segment and the average heart rate AHR2 of the second exercise load segment is the heart rate reserve change value.

[0084] In some embodiments, the difference between the average heart rate AHR1 of the first exercise load segment and the average heart rate AHR2 of the second exercise load segment is the heart rate reserve change value, which specifically includes:

[0085] Draw a t-RR scatter plot of the electrocardiogram for the entire 1-hour process to show the changes in the RR interval of heart beat N;

[0086] Draw a heart rate trend chart for the entire 1-hour journey;

[0087] Establish a landmark line for the test-treatment time period, including the pre-treatment load exercise period, the transthoracic ultrasound treatment period, and the post-treatment exercise period, as well as the two sides without test treatment content, and separate them by background color;

[0088] Draw a reference line in the immediate efficacy evaluation analysis chart of cardiac rehabilitation to visually judge the changes in heart rate;

[0089] Based on AHR1 and AHR2, the corresponding average heart rate values ​​are marked in the diagram, and the difference between the two is displayed.

[0090] Specifically, see Figure 3 , where the horizontal axis of the coordinate is time, the vertical axis is the RR interval, and the black line is the heartbeat N, that is, the heartbeat transmitted to the ventricle by sinus excitation, which is the mainstream heartbeat. The black line in the coordinate is the time RR interval scatter plot, also known as the t-RR scatter plot, and the red horizontal line below is the reference line for visual judgment. The closer the black curve is to the red reference line, the faster the heart rate. The narrower the gap between the two lines, the faster the heart rate.

[0091] Step S4, based on the constructed myocardial load carrying capacity model, determining the myocardial load carrying capacity index MEEI according to the heart rate reserve change value, the height and weight of the subject;

[0092] In some embodiments, the myocardial load carrying capacity index MEEI is determined based on the constructed myocardial load carrying capacity model according to the heart rate reserve change value, the subject's height and weight, specifically including: determining the myocardial load carrying capacity index MEEI according to MEEI=0.275(AHR1-AHR2)*0.0167W-0.0059H, wherein W is the subject's weight, and H is the subject's height.

[0093] Step S5: determining the evaluation result of the immediate therapeutic effect of cardiac rehabilitation according to the myocardial load bearing capacity index MEEI;

[0094] In some embodiments, the evaluation result of determining the immediate therapeutic effect of cardiac rehabilitation according to the myocardial load carrying capacity index MEEI specifically includes:

[0095] When MEEI≥2, the evaluation result of the immediate therapeutic effect of cardiac rehabilitation is that the heart rate reserve is improved compared with the previous time; when MEEI<2 but≥-0.6, the evaluation result of the immediate therapeutic effect of cardiac rehabilitation is that the heart rate reserve has not changed much; when MEEI<0.6, the evaluation result of the immediate therapeutic effect of cardiac rehabilitation is that the heart rate reserve has decreased.

[0096] Specifically, when the cardiac exercise load variable is fixed, the heart rate is fast, the heart rate reserve is more, and the myocardial load endurance is small; conversely, the heart rate is slow, the heart rate reserve is less, and the myocardial load endurance is large. In other words, when MEEI ≥ 2, the evaluation result of the immediate effect of cardiac rehabilitation is determined to be an improvement in the heart rate reserve compared with the previous time, and the immediate effect of cardiac rehabilitation is good this time; when MEEI < 2 but ≥ -0.6, the evaluation result of the immediate effect of cardiac rehabilitation is determined to be that the heart rate reserve has not changed much, and the immediate effect of cardiac rehabilitation is small this time; when MEEI < 0.6, the evaluation result of the immediate effect of cardiac rehabilitation is determined to be a decrease in the heart rate reserve, and the immediate effect of cardiac rehabilitation is not suitable for the patient. During the implementation of cardiac load exercise, height and weight factors have an impact on the test results. For example, tall people with long legs have slightly less work to do than short people with short legs. Obese people with high body weight have more effort to complete the same load than thin people with light body weight. Men's heart rate is generally slightly lower than that of women, but men can withstand more load than women. Gender factors have little effect. The detection and evaluation of biological work indicators are relatively complicated, but these factors are completely consistent in the before and after comparison process and are eliminated by the design plan.

[0097] In other words, by designing comparative indicators before and after treatment, the biological work indicators with high hardware costs are eliminated, thus achieving the goal of low instrument hardware costs and laying a solid foundation for the popularization of technology. Therefore, after treatment, the qualitative judgment of the slowing heart rate is a reliable basis for whether the treatment is effective. The greater the difference in the control results, the greater the increase in the heart rate reserve and the more obvious the treatment effect.

[0098] In some embodiments, it is also possible to collect 12-lead ECG data for 1 hour; play back data; establish medical records; digitally process (filter) ECG signals; automatically analyze and identify heartbeat attributes; provide an analysis interface and editing tools for automatic error correction of heartbeat annotations, such as cluster analysis templates for ECG wave morphology, scatter plots for editing heartbeat rhythms, and linkage editing of 3 graphs composed of instant segment ECGs;

[0099] The final result of cluster analysis is to distinguish those components that are not required for calculation, such as ectopic heart beats, paced heart beats and reentry / circulation, extract the continuous sinus heart beat NN components, and prepare materials for subsequent calculations; perform color-coded diagrams and annotations for various types of heart beats.

[0100] In some embodiments, a 1-hour t-RR scatter plot is drawn; a 1-hour heart rate trend plot is drawn; the HR trend plot is hidden by default in both plots, and the drop-down menu has two display modes to choose from; a marker line for the test-treatment time period is established: the pre-treatment load exercise period, the transthoracic ultrasound treatment period, and the post-treatment exercise period, as well as the parts without test treatment content on both sides; each period is separated by background color; each period is labeled with text; a reference line is drawn, which can be activated by a mouse drag event and moved up and down at will; the average heart rate AHR1 of the 6-minute exercise load period before ultrasound treatment is calculated as a control value for the change in heart rate reserve; and the average heart rate AHR2 of the exercise load period 30 minutes after ultrasound treatment is calculated. The two average heart rates are compared, and the difference between the two is calculated for reference by clinicians when making evaluations.

[0101] In some embodiments, the myocardial load carrying capacity model is constructed as follows:

[0102] MEEI=0.275(AHR1-AHR2)*0.0167W-0.0059H

[0103] For example: Male, 56 years old, healthy, height 182cm, weight 92kg

[0104] Test data: AHR1: 108bpm, AHR2: 102bpm MEEI: 1.46

[0105] Clinical significance of MEEI:

[0106] When MEEI≧2, it indicates that the heart rate reserve of the next test is better than that of the previous test;

[0107] When MEEI < 2 but ≧ -0.6, it indicates that the heart rate reserve does not change much between the two tests;

[0108] When MEEI<0.6, it indicates that the heart rate reserve of the subsequent heart is lower than that of the previous heart.

[0109] The MEEI index is designed to facilitate the judgment of clinicians.

[0110] The technical solution of this embodiment is adopted to disclose a method for evaluating the immediate effect of cardiac rehabilitation, which is suitable for the detection and evaluation of short-term effect, and solves the problems that the existing instruments and equipment for evaluating cardiopulmonary function are expensive, the examination cost is expensive, the operation is complicated, the detection indicators are cumbersome, the medical staff are difficult to master, and it is not suitable for popularization in primary medical units and screening of a large number of treatment indications. The hardware support structure of this technology is low-cost, and the evaluation of cardiac reserve function can be expanded or used in other treatment methods. It has the advantages of accurate measurement, good repeatability, sensitive indicator response, rapid results, convenient operation, low examination cost, and easy popularization.

[0111] The method of the present application is further described below in conjunction with specific embodiments:

[0112] For example: The examinee is a 57-year-old male who is healthy. He has a family history of hypertension. Height: 183cm, weight: 76kg.

[0113] Purpose of the study: To detect and evaluate the immediate myocardial endurance enhancement effect after transthoracic ultrasound therapy.

[0114] The ultrasound therapy device used was the DM-300E model, and the precordial area was treated through the chest for 30 minutes;

[0115] The iH-12MT 4G Holter monitor is used for 12-lead ECG monitoring and data collection throughout the entire process, the iH-B dynamic electrocardiograph is used for blood pressure monitoring throughout the entire process, and the BP-10M finger-clip blood oximeter is used for blood oxygen saturation monitoring throughout the entire process to ensure the safety of the medical process.

[0116] Before treatment: do the first load exercise test: sit still for 5 minutes, that is, continue the static state for the first time, walk for 2 minutes under the guidance of the metronome (set the cadence to 56, damping 1 / 6), that is, continue the warm-up state for the second time, then continue to exercise for 4 minutes (set the cadence to 80, damping 3 / 6), terminate the exercise, that is, continue the high-load exercise for the third time.

[0117] Treatment: Transthoracic ultrasound treatment for 30 minutes.

[0118] After treatment: Repeat the first load exercise test before treatment, sit still for 5 minutes, walk for 2 minutes, and continue to exercise for 4 minutes.

[0119] In some embodiments, when the first load exercise test before treatment is repeated after treatment, the 5-minute sitting can be cancelled, and the pre-walking for 2 minutes can be performed directly, and the exercise can be continued for 4 minutes. Because the patient is sitting during treatment, the sitting part can be cancelled to shorten the evaluation time.

[0120] It should be noted that the specific pre-walking time and exercise time can be determined according to the physical fitness of the subject. The ideal load is to make the subject's heart rate about 110 beats / minute. Since the physical fitness of the subjects is different, the pre-walking can be used to estimate the load to be set, and the pre-walking time and exercise time can be determined. For example, subjects with better physical fitness can set the pre-walking time to 1 minute and the exercise time to 5 minutes, and subjects with poorer physical fitness can set the pre-walking time to 2 minutes and the exercise time to 4 minutes. The specific time depends on the situation, as long as the two load exercise tests on the same subject before and after treatment are completely consistent.

[0121] The present invention collects ECG data until termination, and no abnormal events of ECG, blood pressure and blood oxygen saturation occur during the entire inspection process.

[0122] For example, the results are: AHR1: 118bpm, AHR2: 104bpm, and the MEEI value is 3.81.

[0123] If MEEI≧2, it indicates that the heart rate reserve in the subsequent test is better than that in the previous test.

[0124] In the embodiment of the present application, a device for evaluating the immediate therapeutic effect of cardiac rehabilitation is provided. Figure 4 , Figure 4 2 is a diagram of an evaluation device for the immediate therapeutic effect of cardiac rehabilitation in an embodiment, wherein the evaluation device for the immediate therapeutic effect of cardiac rehabilitation comprises an AHR1 determination module 201, an AHR2 determination module 202, a heart rate reserve change value determination module 203, a MEEI determination module 204 and an evaluation result determination module 205.
