Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of an electrocardiographic blood pressure on-screen display method provided by the application. The method comprises the following steps:

step 11: and acquiring electrocardio data.

In some embodiments, blood pressure data may also be acquired.

In some embodiments, electrocardiographic data and blood pressure data may be acquired using a wearable device. Wherein, the wearable device may include a wearable electrocardiograph acquisition device and a wearable blood pressure acquisition device.

The wearable electrocardio acquisition device and the wearable blood pressure acquisition device can be arranged in a centralized manner on an electrocardio blood pressure same screen display device. For example, a wearable electrocardiograph acquisition device, a wearable blood pressure acquisition device and an electrocardiograph blood pressure same-screen display device are used as a master-slave mode. The electrocardio-blood pressure same-screen display device is a host end, and the wearable electrocardio-acquisition device and the wearable blood pressure acquisition device are slave ends.

The wearable electrocardio acquisition device, the wearable blood pressure acquisition device and the display device of biological detection information are in communication connection.

The electrocardiograph data and the blood pressure data can be local original data acquired by a sensor assembled on the electrocardiograph blood pressure same-screen display device, or electrocardiograph data and blood pressure data transmitted by other application ends. The wearable electrocardio acquisition device and the wearable blood pressure acquisition device can be formed by using the sensor.

For example, the electrocardiographic data may be obtained by converting an electrocardiographic signal acquired by an electrocardiographic data sensor, and the blood pressure data may be obtained by converting a blood pressure signal acquired by a blood pressure data sensor.

For acquiring electrocardiosignals, an electrocardio data acquisition unit can be worn on the limbs and the chest of a user, and the electrodes of the electrocardio data acquisition unit are contacted with a human body to acquire the heart electric activity signals of the user. Further, an electrocardio-blood pressure linkage detection device is used for receiving the electrocardio-activity signal of the electrocardio-data acquisition device, the electrocardio-activity signal is filtered by a low-pass filter to remove an interference common-frequency notch, and the filtered electrocardio-activity signal is subjected to data conversion by an Analog-to-Digital Converter (Analog-to-digital converter) to form electrocardio data.

Specifically, the acquired electrocardiographic data includes an acquisition period, an acquisition time, electrocardiographic parameters corresponding to electrocardiographic segments, and electrocardiographic events determined according to the electrocardiographic parameters. The electrocardiographic parameters corresponding to the electrocardiographic fragments comprise at least one of average heart rate, slowest heart rate, heart beat type, heart beat position, interval parameters, waveform parameters, fastest heart rate and total number of heart beats, and the electrocardiographic events comprise at least one of atrial premature beat, atrial speed, ventricular premature beat, single-shot ventricular premature beat, paired ventricular premature beat, ventricular speed and ventricular bivariate.

Optionally, electrodes are placed at different parts of a human body through an electrocardiograph data collector in a multi-lead mode, different leads are formed between every two electrodes or between the electrodes and a central potential end, and the electrodes are connected with the positive electrode and the negative electrode of an electrocardiograph ammeter through lead wires to record the electrical activity of the heart. The electrocardio data acquisition device comprises an electrocardio data acquisition device, a blood pressure display device and a data analysis device, wherein the number of leads of the electrocardio data acquisition device comprises 8 leads, 12 leads, 18 leads and the like, and the electrocardio data acquisition device can comprise a plurality of lead switching modes for acquiring and analyzing electrocardio data of different numbers of leads.

For collecting blood pressure signals, a blood pressure data collector can be worn on the limbs of a user, a main controller connected with the blood pressure data collector is utilized to control an air pump to inflate a cuff of the blood pressure data collector to a certain pressure value, the blood pressure is ensured to exceed the systolic pressure of a blood vessel, the blood flow is blocked, and then the air pump is controlled to deflate stepwise at a speed. During deflation, a primary pressure sensor located in the blood pressure data acquisition device converts pressure signals within the cuff into blood pressure electrical activity signals. Further, the electrocardio-blood pressure linkage detection device acquires a blood pressure electric activity signal of the blood pressure data acquisition device, filters the blood pressure electric activity signal through a low-pass filter to obtain a static pressure signal and a pulse signal of the cuff, and then performs data conversion on the static pressure signal and the pulse signal through the ADC analog-digital converter to form blood pressure data.

Specifically, the acquired blood pressure data includes a plurality of sets of blood pressure parameters, and an acquisition time of each set of blood pressure parameters. The blood pressure data acquisition device acquires blood pressure data once every other preset time to obtain a group of blood pressure parameters. Each set of blood pressure parameters includes at least one of an acquisition date, an acquisition time, a systolic pressure, a diastolic pressure, an average arterial pressure, a pulse rate, a posture feature, and an error code.

In some embodiments, the blood pressure data collector is from 10 on a day: 00 starts to collect blood pressure data every 2 hours, and 5 times of blood pressure data are collected in total. Namely, the acquired blood pressure data comprises five groups of blood pressure parameters, and the acquisition time corresponding to each group of blood pressure parameters is respectively 10: 00. 12: 00. 14: 00. 16: 00. 18:00 and 20:00.

optionally, the electrocardio-blood pressure same screen display device is respectively connected with the electrocardio-data collector and the blood pressure data collector. The controller of the electrocardio data collector and the controller of the blood pressure data collector are arranged in the electrocardio-blood pressure linkage detection device, and the electrocardio-blood pressure linkage detection device can be respectively in communication connection with the electrocardio data collector and the blood pressure data collector in a mode of using special communication protocols such as USB (Universal Serial Bus ), bluetooth or serial port. The electrocardio-blood pressure linkage detection device is used for controlling the electrocardio-data collector and the blood pressure data collector to carry out data collection tasks, setting data collection parameters, analyzing electrocardio-data and blood pressure data tasks and displaying related charts under different scenes. The electrocardio-blood pressure same-screen display device can also print corresponding data, analysis results, graphs/tables and other information or output report documents.

Optionally, the electrocardiographic blood pressure on-screen display device comprises an input module and a human-computer interface. The input module is used for inputting control signals to the electrocardio-blood pressure on-screen display device to control the electrocardio-blood pressure on-screen display device to run, such as inputting control signals for configuring acquisition modes (such as a single electrocardio mode, a single blood pressure mode and an electrocardio-blood pressure adding mode), acquisition duration, start-stop time, interval time and special function parameters (such as detection frequency parameters, early warning value parameters, channel number parameters and sampling rate parameters) and the like, so as to complete the function parameter configuration of the electrocardio-blood pressure on-screen display device, save the function parameter configuration, and facilitate subsequent continuous use. The human-computer interface is used for providing a user operation interface, such as an acquisition mode selection main interface for selecting electrocardiographic data acquisition or blood pressure data acquisition, a functional mode working interface for displaying electrocardiographic data or blood pressure data, a parameter setting interface for configuring acquisition data, and the like. For example, a certain piece of blood pressure data or electrocardiographic data can be set as invalid data through the input module, and the certain piece of blood pressure data or electrocardiographic data can be modified.

Specifically, the upper edge area of the human-computer interface comprises an option menu bar, and the application interface of the corresponding option can be displayed when the corresponding option identifier is selected and determined by the input module of the electrocardio-blood pressure linkage detection device. Wherein the option menu bar includes: patient information, templates, electrocardiographic analysis results, blood pressure analysis results, atrial fibrillation/atrial flutter, events, electrocardiographic analysis graphs, blood pressure analysis graphs, superposition graphs, scatter graphs, trend graphs, lists, statistical information, reports and other option identifiers, for example, the input module selects and determines a blood pressure analysis graph option, and then the human-computer interface displays corresponding blood pressure analysis graph information, such as a blood pressure histogram or a blood pressure circadian rhythm graph, marks thereof and the like. The human-computer interface of the electrocardio-blood pressure same-screen display device can input a selection instruction by the input module, and a corresponding display scheme is set according to the selection instruction. Optionally, displaying the protocol includes displaying any one or any combination of several of the electrocardiographic analysis results or blood pressure analysis results and their corresponding analysis maps or statistical maps/tables.

Alternatively, the input module may be a key input or a voice input. The key input device can comprise a plurality of keys, and the voice input device can comprise a plurality of voice keywords for inputting different control signals to the same-screen display device of the blood pressure. For example, the key input device may include four keys, namely a confirm key, a left key, a right key and a self-rescue key, where the confirm key, the left key and the right key are used for performing interface operation on a human-computer interface and inputting corresponding control signals to the on-screen display device of the electronic blood pressure. The self-rescue key is one-key triggering type, and the electrocardio-blood pressure same-screen display device receives a control signal sent by the self-rescue key and immediately starts a self-rescue mode. For example, the plurality of voice keywords in the voice inputter include the same functions as the plurality of keys in the key inputter. For example, a voice keyword is "blood pressure analysis chart", the voice input unit recognizes the keyword and sends a corresponding control signal to the on-screen display device for the electrocardiograph blood pressure, and the on-screen display device for the electrocardiograph blood pressure immediately displays the blood pressure histogram or the circadian rhythm chart of the blood pressure in the human-computer interface and provides operational functional options, such as modifying the blood pressure data, viewing the blood pressure data chart, and the like.

Step 12: and carrying out atrial fibrillation analysis on the electrocardio data to obtain a corresponding electrocardio analysis result.

Specifically, atrial fibrillation is divided into whole-course atrial fibrillation, long Cheng Fang atrial fibrillation and paroxysmal atrial fibrillation, and when atrial fibrillation occurs, the normal functions of hemodynamics can be seriously affected by the factors such as loss of synchronous mechanical activity of the heart, irregular ventricular response, and too high heart rate, so that various cardiovascular diseases with high death risk degree are caused. Therefore, atrial fibrillation analysis can be performed according to the electrocardio data, and diagnosis and study can be found and assisted as early as possible, so that the method has important significance for improving treatment countermeasures and treatment quality of patients, reducing incidence rate and death rate of critical diseases of the patients and the like.

Referring to fig. 2, step 12 may be the following steps.

Step 21: and analyzing the electrocardio data to obtain RR interval parameters.

As shown in fig. 3, fig. 3 is a schematic diagram of one cardiac cycle in electrocardiographic data. Wherein the abscissa of the cardiac cycle represents time and the ordinate of the cardiac cycle represents the detected signal value (e.g. voltage value) (the abscissa is not shown in fig. 3). Wherein a plurality of cardiac cycles are included in the global electrocardiographic data, each cardiac cycle representing a beat, one cardiac cycle being shown in fig. 3. Specifically, the heart beat parameters of one cardiac cycle mainly include PR interval and QT interval, which in turn includes QRS interval and JT interval. The heart beat parameters included between each interval are P-wave, Q-wave, R-wave, J-wave, T-wave and U-wave. Wherein the R wave between two cardiac cycles is the RR interval. One or a combination of any of the above-mentioned beat parameters is extracted in the electrocardiographic data, and the extracted beat parameters include at least RR interval parameters of each beat.

In one embodiment, as shown in fig. 4, fig. 4 is an electrocardiographic diagram of an embodiment of an electrocardiogram corresponding to electrocardiographic data. In the electrocardiogram of fig. 4, the electrocardiograph data has a start acquisition time of T1 and an end acquisition time of T4, which correspond to the cardiac cycles at which B and E are located, respectively, and four cardiac cycles C, A, D, E are further included after B is set, and the cardiac cycle position of a is T2-T3. The RR interval starts at time T5 and ends at time T6.

Wherein the RR interval is the interval between each heart beat. Because the electrocardiogram is measured by measuring the distance between two R waves, the interval between two heart beats is called RR interval. The heart chamber is the main part of heart beating, the QRS wave is the representation and record of the heart electrical variation of the heart chamber contraction on the electrocardiogram, the time interval between two heart beats is calculated, and the heart beating RR interval can be obtained by measuring the distance between two R waves on the electrocardiogram and converting.

It will be appreciated that a plurality of cardiac cycles may be included in the cardiac data, and in this embodiment, cardiac data for all cardiac cycles of the period may be acquired, and cardiac data for a portion of the cardiac cycles within the period may also be acquired, where the portion of the cardiac cycles should be continuous. For example, in one embodiment, where the cardiac data includes 24 hours of cardiac cycles, the cardiac data for all 24 hours of cardiac cycles may be acquired for subsequent processing operations, and the cardiac data for successive 12 hours of cardiac cycles may be acquired for subsequent processing operations.

In some embodiments, in response to the result of the electrocardiographic analysis being an electrocardiographic anomaly, determining a blood pressure data segment corresponding to the acquisition time in the blood pressure data, the electrocardiographic anomaly including a value of SDNN of less than 50, a first atrial fibrillation or a paroxysmal atrial fibrillation, atrial fibrillation information corresponding to P-wave disappearance or replacement by irregular f-waves, or irregular RR intervals, or an atrial fibrillation frequency of 350-600 times/minute.

In some embodiments, the data segments of the electrocardiograph may be analyzed for ST segments, resulting in ST analysis results. And responding to the ST analysis result as abnormality, and outputting at least blood pressure data corresponding to the abnormality or blood pressure analysis results obtained after analyzing the blood pressure data. Specifically, in response to ST abnormality raised by one millimeter or pressed against by one millimeter, at least the blood pressure data corresponding to the abnormality or a blood pressure analysis result obtained after analyzing the blood pressure data is output. For example, raised by more than one millimeter or pressed against more than one millimeter on the ordinate of the electrocardiogram.

When the ST segment data graph is raised by more than one millimeter or pressed against by more than one millimeter in a sudden manner, the ST is shown to be abnormal, the physical condition of the user is abnormal in a high probability, and corresponding blood pressure data or analysis results corresponding to the abnormality are required to be output so as to help analyze and judge the physical condition of the user. Here, one millimeter is a schematic abnormal data amount, which is a degree of improvement in a conventional display data trend chart, and is changed specifically in accordance with the ordinate data of the data chart.

Further, in response to the ST continuously raising the set raised amount or continuously pressing against the set depressed amount for a preset time, both the set raised amount and the set depressed amount are less than one millimeter, the blood pressure measuring device is controlled to be turned on to prepare for blood pressure measurement.

When the physical condition of the user is abnormal, blood pressure measurement is needed, and because the blood pressure measurement needs time, in order to conveniently judge the physical condition of the user, complete data when the physical condition of the user is abnormal is obtained, and the blood pressure measurement needs to be started in advance when abnormal ST data occurs. If the ST data is continuously raised or pressed over a certain period of time, it indicates that there is a certain continuous trend of change, and the probability of the ST data in the future in the near period of time will continue to change along the previous trend of change, which also indicates that the user may be about to have a physical abnormality. At this time, the blood pressure measurement is started, and the blood pressure measurement device is started. The set elevation and the set depression are each less than one millimeter.

Step 22: and drawing an RR interval analysis chart generated based on the RR interval parameters as an electrocardio analysis result.

For example, RR interval trend graphs are plotted for RR intervals over time.

In some embodiments, an RR interval analysis graph is established according to RR interval parameters, including any one or combination of an RR interval scatter trend graph and an RR interval dispersion trend graph. The RR interval scattered point trend graph is used for representing the change trend of RR intervals along with time, the RR interval dispersion trend graph is used for representing the change trend of RR interval dispersion along with time, and the RR interval dispersion is used for representing the dispersion degree of adjacent RR intervals.

Taking RR interval scattered point trend chart as an example:

as shown in FIG. 5, FIG. 5 is an electrocardiographic plot of one embodiment of an RR interval scatter plot. In general, 24-hour heart beats have 10 tens of thousands of times, and the 10 tens of thousands of heart beats are considered as a whole for study, which is the overall view of heart rhythm. The sinus RR intervals of the cardiac cycle in the time domain are also called NN intervals. The computer is used for identifying the QRS waves of the electrocardiosignals obtained by 24-hour synchronous multi-lead electrocardiogram record one by one, removing the non-sinus QRS waves, digitizing the electrocardiosignals and obtaining a series of mathematical statistics indexes related to RR intervals. The 24-hour RR interval scatter plot depicts over 10 tens of thousands of heart rhythms in a visual two-dimensional coordinate system. The 24-hour RR interval scatter plot is used to represent the trend of RR intervals over time. Which is also referred to as a rate trend graph.

The drawing principle of the 24-hour RR scattered point trend graph is that the specific time of occurrence of R wave is taken as an abscissa, and the interval between the R wave and the previous R wave is taken as an ordinate. The position of each scatter in the coordinate system represents both the moment at which it occurs and the length of its RR interval. The time axis is shortened by a computer, and more than 10 ten thousand scattered points of 24 hours are compressed in a visual field, which is shown as a solid line. The width of the "solid line" represents the difference of RR intervals, and the fluctuation of the "solid line" represents the rapid and slow change of the rhythm, and the higher the amplitude, the slower the heart rate; the lower the amplitude, the faster the representative heart rate. Therefore, the 24-hour RR interval scatter plot can intuitively reflect the 24-hour rhythm and the change with time of the whole heart, and analysis of the 24-hour RR scatter plot can provide an overall view for diagnosing heart rhythm. When there is still difficulty in diagnosing a rhythm, such as the presence of sporadic individual points or atypical scatter plot features, a scatter inversion technique, i.e., regression from a scatter to a segmented electrocardiogram corresponding to the point, may be employed. The whole dominant rhythm can be determined according to the scattered point graph, and the corresponding electrocardiogram can be analyzed according to the scattered point; the RR interval scatter trend graph can be used for evaluating heart rate fluctuation, autonomic nervous regulation and heart rate variability; can also be used for diagnosing arrhythmia and evaluating disease prognosis.

Taking RR interval dispersion trend chart as an example:

and drawing an RR interval dispersion trend chart of the change of the RR interval dispersion along with time, wherein the RR interval dispersion is determined by the difference value of two adjacent RR intervals.

As shown in FIG. 6, FIG. 6 is an electrocardiographic plot of one embodiment of an RR interval dispersion trend graph.

Specifically, the RR interval dispersion trend graph is used to represent the trend of the RR interval dispersion with time, and the RR interval dispersion is used to represent the degree of dispersion of adjacent RR intervals. The step of obtaining RR interval dispersion includes: acquiring the time difference between adjacent intervals in the 24-hour RR interval; the dispersion of 24-hour RR intervals was calculated from the time differences.

Specifically, the R peaks of 3 heartbeats are set to R1, R2 and R3 in time sequence, respectively, then the two RR intervals are R1R2 and R2R3, respectively, and then the dispersion of the RR intervals of these 3 heartbeats is s1= (r2r3—r1r2)/r1r2, where R1R2 is the period between R1 and R2, and R2R3 is the period between R2 and R3. Similarly, the dispersion of 24-hour RR intervals is S2, S3, S4, etc. And correspondingly drawing a 24-hour RR interval dispersion trend chart by taking the midpoint time of each RR interval as an abscissa and the dispersion of the RR interval as an ordinate. The RR interval dispersion trend graph is a trend graph which records RR interval dispersion in real time according to a time sequence, and on the trend graph, the brighter the area is, the higher the RR interval dispersion is, so that the occurrence of atrial fibrillation is indicated; darker areas indicate low RR interval dispersion, indicating no atrial fibrillation here. In other embodiments, atrial fibrillation occurrence regions may be further analyzed and confirmed using atrial fibrillation variability parameters, waterfall graphs, or power profiles.

Optionally, the area in which atrial fibrillation may exist in the trend chart is determined by the dispersion of each time point in the RR interval dispersion trend chart.
