[0001] The present invention relates to the technical field of electrocardiogram monitoring, and in particular to a patch-type electrocardiogram signal monitoring system. Background Art

[0002] Currently on the market, only the dynamic electrocardiograph can measure a 12-lead electrocardiogram at the same time.

[0003] The wearable and portable ECG patch that eliminates the hassle of wires is currently the product with the largest number of measuring leads, capable of monitoring lead II and leads V3 and V5.

[0004] However, there are no ECG patch-type products on the market that can simultaneously measure limb leads, pressurized limb leads, and chest leads. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide a patch-type ECG signal monitoring system that can simultaneously measure limb leads, pressurized limb leads and chest leads.

[0006] To achieve the above-mentioned purpose, an embodiment of the present invention provides a patch-type ECG signal monitoring system, including an ECG patch, a bracelet and an AI server. The ECG patch is used to monitor the user's ECG data in real time around the clock, and transmit the ECG data to the bracelet and the AI ​​server.

[0037] 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 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.

[0038] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0039] Please refer to Figure 1The patch-type ECG signal monitoring system provided by the embodiment of the present invention includes an ECG patch, a wristband and an AI server. The ECG patch is used to monitor the user's ECG data in real time around the clock, transmit the ECG data to the wristband and the AI ​​server, and the AI ​​server is used to perform intelligent analysis on the ECG data to realize heart disease monitoring and danger signal warning.

[0040] The ECG chip includes a host and an FPC inside the tape. The host is used to collect ECG data and transmit the ECG data to the bracelet via low-power Bluetooth; the FPC inside the tape is used to provide an electrical connection between the host and the user's body leads.

[0041] like Figure 2 As shown in FIG. 1 , the tape of the ECG chip is in the shape of an I-shaped ribbon and is provided with a plurality of contact points. Figure 3 As shown, the "I"-shaped ECG patch includes the first braiding area, the second braiding area, the third braiding area and the fourth braiding area, and the corresponding lead points are RA, LA, RL and LL respectively, and the fourth braiding area also corresponds to the lead points V1-V6. Figure 4 shown.

[0042] Furthermore, the wristband of this embodiment has BLE, PPG, data upload function, whitelist incoming call function and emergency contact outgoing call function, etc.

[0043] In specific implementation, the AI ​​server is used to perform intelligent analysis on the ECG data, specifically:

[0044] Based on the nature of ECG vector projection and the principle of lead conversion, the leads with a projection axis angle close to 90° are taken as source leads. The operation coefficients of the source leads are calculated using the intrinsic geometric relationship between the lead axis and the projection axis, and the remaining leads are calculated using analysis software.

[0045] Please refer to Figure 5 In the Einstein triangle, since I = LR, II = FR, III = FL, I + III = (LR) + (FL) = FR = II. This formula is the famous Einstein's law, which shows the internal connection between the three standard leads and also expresses the rationality of lead conversion, that is, the unknown lead (such as III) can be derived from the known leads (such as I and II). Figure 6It can also be seen that the three standard leads just form a parallelogram, which is the law of vector operation and embodies the idea of ​​combining numbers and shapes. Similarly, the pressurized unipolar limb leads can also be derived from leads Ⅰ and Ⅱ, and we can get aVR=-(Ⅰ+Ⅱ) / 2, VL=(Ⅰ-Ⅱ) / 2, aVF=(Ⅱ-Ⅰ) / 2, which can be regarded as the generalization of Einstein's law. It can be seen from the figure that the operations between them all conform to the parallelogram law. Only when the vector nature of the lead is recognized, lead conversion is a very natural thing. It is also feasible to predict the lead conversion in the chest lead, but the determination of the conversion coefficient is relatively complicated. Another point to note is that compared with the limb lead, the chest lead is a relatively "near field", the projection theory will be slightly lost, and the error may be slightly larger, which can be compensated by adjusting the conversion coefficient.

[0046] Please refer to Figure 7 The lead axis and projection axis of the chest lead described above can simulate not only the frontal plane six-lead synchronous electrocardiogram, but also the transverse plane six-lead synchronous electrocardiogram according to the principle and method of lead conversion, indicating that by adjusting the operation coefficient of the source lead, the target lead electrocardiogram at any orientation in the source lead plane can be synthesized. The current transverse plane six-axis system can also be further simplified. This model provides a method for simplifying the current transverse plane six-axis system:

[0047] The leads with a projection axis angle close to 90° are taken as source leads (such as V1 and V4 leads), and the operation coefficients of the source leads are calculated based on the intrinsic geometric relationship between the lead axis and the projection axis. In this way, the remaining four leads can be calculated using analysis software.

[0048] Please refer to Figure 8 , the specific calculation process is:

[0058] The following is a detailed description of the specific process of using the ECG patch to measure chest leads:

[0059] Vector Cardiology Theory

[0060] 1. Relationship between ECG signal projection and ECG vector loop

[0061] "Cardiac electrical activity" is essentially a bioelectric phenomenon. In the cardiac cycle, the heart will generate a potential difference (potential difference) with both magnitude and direction at each moment. This potential difference is called a "vector" in physics. Connecting the running tracks of the comprehensive cardiac electrocardiogram vectors generated at each moment in each cardiac cycle will form a hypothetical three-dimensional cardiac electrocardiogram vector loop. Electrocardiogram (ECG) is a science that records and interprets each instant of the comprehensive surface potential difference (or cardiac electrocardiogram vector loop) generated during the cardiac electrical activity.

[0062] The electrocardiogram is the projection result of the three-dimensional electrocardiogram vector ring on the two-dimensional plane and the one-dimensional line. The three-dimensional electrocardiogram vector ring will correspond to the electrocardiogram waveform. Conversely, the shape of the three-dimensional electrocardiogram vector ring can also be inferred from the electrocardiogram waveform.

[0063] 2. The manifestation of the electrocardiogram vector loop in the Einstein triangle

[0064] The electrocardiogram is the dot product of the electrocardiogram vector ring and the lead vector (projection axis). There is no essential difference between unipolar lead electrocardiogram and bipolar lead electrocardiogram, and both can be represented by a projection axis. The projection axis is a vector axis, and its composition and decomposition conform to the parallelogram law. The projection axis of the standard lead is the three sides of the "Einstein triangle". According to the parallelogram law, we can get III=II-I. The projection axes of leads I and II are the two sides of the Einstein triangle, and the projection axis of lead III is the third side of the Einstein triangle. Figure 9a and Figure 9b. In "Geometry Sketchpad", measure the polar coordinate distance and polar coordinate direction of leads Ⅰ and Ⅱ, measure the polar coordinate distance and polar coordinate direction of the electrocardiogram vectors P, R, and T again, calculate the dot product of the electrocardiogram vector and the projection axis, and obtain the potential of leads Ⅰ and Ⅱ; make a point t on the x-axis, measure its horizontal coordinate (xt), and make three points GⅠ (xt, GⅠ+yⅠ), GⅡ (xt, GⅡ), and GⅢ (xt, GⅡ-GⅠ+yⅢ) in the rectangular coordinate system (yⅠ and yⅢ represent the baseline heights of leads Ⅰ and Ⅲ, respectively), representing the potential of standard leads Ⅰ, Ⅱ, and Ⅲ, respectively. When P, R, and T move on each ring, point t moves to the right at a uniform speed along the x-axis, and points GⅠ, GⅡ, and GⅢ move accordingly and leave trajectories, and the mathematical model of the standard three-lead synchronous electrocardiogram is obtained. It can be seen that it is consistent with the actual recorded standard lead electrocardiogram. Figure 10 Similar.

[0065] 3. Calculation method for project testing phase

[0066] All calculation theories in this section are based on the ECG vector loop and ECG signal projection theory.

[0067] The WCT point is established through LA, RA, and LL, and two non-parallel vectors starting from the WCT point and ending at the electrode point are collected on the annular surface of the body at the level and slightly below the heart. The angle between the two vectors is as close to 90° as possible (the angle between the chest lead vectors can be roughly referred to Fig.10 The word vector can refer to V2 and V6 in the standard 12-lead electrocardiogram.

[0068] According to the projection theory, the ECG signals detected in all directions on the body surface are the projections of the bioelectric signals initiated by the heart at the corresponding angles. Mathematically, the projections in all directions on a plane can be obtained through vector calculation using two non-parallel vectors on the plane.

[0069] If used Fig.10 V4 is calculated from V2 and V6, then V4 = V2*cos(30°)+V6*cos(60°). Similarly, vectors in other directions can also be calculated by this method, but since the angles between most vectors cannot reach 90° like V2 and V6, a more complex calculation formula is needed in the calculation method. The vector results calculated by this method are as follows Fig.11a and Fig.11b shown.

[0070] The above calculation methods are all based on a circle as the reference model, that is, the distance from each point on the body surface to the heart is the same, and the calculated results are obtained. However, the cross-sectional shape of the human body is roughly an ellipse. When using vector calculation, it is necessary to consider introducing a vector calculation model based on an ellipse and calculate the ECG signals in multiple directions on the same horizontal plane.

[0071] The embodiment of the present invention provides a patch-type ECG signal monitoring system, including an ECG chip, a bracelet and an AI server. The ECG patch is used to monitor the user's ECG data in real time around the clock and transmit it to the bracelet and the AI ​​server. The AI ​​server is used to perform intelligent analysis on the ECG data to achieve heart disease monitoring and danger signal warning. The ECG chip can simultaneously measure limb leads, pressurized limb leads and chest leads, filling the gap in existing ECG patch products.

[0072] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
