Description

[Technical Field]

[0001] The present disclosure relates to methods for inducing additional measurements of electrocardiogram signals, and more particularly to methods for inducing additional measurements of other types of electrocardiogram signals. [Background technology]

[0002] An electrocardiogram is one of the basic diagnostic methods for heart disease and is an important examination method for diagnosing cardiovascular diseases such as angina pectoris, myocardial infarction, arrhythmia, etc. The heart is a three-dimensional organ, and in order to understand the pathological condition of such an organ using an electrocardiogram, it has been developed to obtain a large amount of information, usually by using multiple leads or by attaching it for a long period of time.

[0003] Electrocardiograms can be broadly divided into standard 12-lead electrocardiograms, which record signals using 10 electrodes, and Holter electrocardiograms, which record electrocardiograms continuously to observe intermittent abnormalities such as arrhythmia.Recently, wearable electrocardiograms (watch-type, patch-type, pad-type) have been developed that make measurement more convenient, but most only measure single-lead signals, and only some products have the function to measure limb lead signals.

[0004] Even if a wearable electrocardiograph has a limb lead function, it does not have a function related to the chest lead signals provided by a standard 12-lead electrocardiograph. Therefore, in the case of cardiac diseases where changes only appear clearly in the chest leads, it is difficult to diagnose the disease using only a single or limb lead.

[0005] Meanwhile, with the rapid advancement of deep learning technology, it is now possible to detect various diseases using only single or limb leads, even without chest lead signals. However, in the case of diseases where changes in chest leads are important for diagnosis, users face a problem of inconsistency between the signals obtained from the actual electrocardiograph and the disease diagnosed using deep learning technology, so ultimately users must confirm the information related to the chest leads. Therefore, it is believed that there is a need to develop an algorithm for guiding chest lead measurements. Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present disclosure is to provide a technique for inducing measurement of another type of electrocardiogram signal in addition to the basic type of electrocardiogram signal. For example, an object of the present disclosure is to provide a technique for identifying a situation in which measurement of a chest lead electrocardiogram signal is required in addition to a single lead electrocardiogram signal or a four limb lead electrocardiogram signal, and for providing feedback regarding such a situation. [Means for solving the problem]

[0007] To achieve the above-mentioned object, a method for inducing an additional electrocardiogram measurement according to an embodiment of the present disclosure is disclosed as a method executed by a processor for inducing an additional electrocardiogram measurement, which may include: acquiring a first type of electrocardiogram signal; and determining whether a second type of electrocardiogram signal different from the first type of electrocardiogram signal is further required based on at least one of information related to the first type of electrocardiogram signal or diagnostic information based on the first type of electrocardiogram signal.

[0013] As an alternative embodiment, the step of determining whether further electrocardiogram signals of the second type are required may include a step of predicting, based on the first type of electrocardiogram signal, a difference between first diagnostic information based on the first type of electrocardiogram signal and second diagnostic information based on the first type of electrocardiogram signal and the second type of electrocardiogram signal; and a step of determining whether further electrocardiogram signals of the second type are required based on the predicted difference.

[0014] As an alternative embodiment, the step of determining whether further electrocardiogram signals of the second type are required includes the steps of inputting the first type of electrocardiogram signal into a first prediction model having a first reference value to generate a predicted value; and determining whether further electrocardiogram signals of the second type are required based on the generated predicted value, wherein the second type of electrocardiogram signal may be for input into a second prediction model having a second reference value, and the first reference value may be set to be different from the second reference value.

[0015] As an alternative embodiment, the step of determining whether further electrocardiogram signals of the second type are needed may include a step of determining that further electrocardiogram signals of the second type are needed if diagnostic information based on the first electrocardiogram signal is generated two or more times within a predetermined period of time and the diagnostic information generated two or more times diagnoses electrocardiogram problems more than a predetermined number of times.

[0016] As an alternative embodiment, the step of determining whether or not further electrocardiogram signals of the second type are required may include the steps of: extracting waveforms of each of a plurality of lead signals included in the first type electrocardiogram signal; and determining whether or not further electrocardiogram signals of the second type are required based on differences in waveforms between the plurality of lead signals.

[0017] Also, there is provided a computer program stored on a computer-readable storage medium for solving the above-mentioned problem, which, when executed by one or more processors, performs an operation of inducing additional electrocardiogram measurements, and the operation may include an operation of acquiring a first type of electrocardiogram signal; and an operation of determining whether a second type of electrocardiogram signal different from the first type of electrocardiogram signal is further required based on at least one of information related to the first type of electrocardiogram signal or diagnostic information based on the first type of electrocardiogram signal.

[0018] Also, a computing device for inducing additional electrocardiogram measurements to solve the above-mentioned problem may include a processor including one or more cores; and a memory, wherein the processor acquires a first type of electrocardiogram signal; and determines whether a second type of electrocardiogram signal different from the first type of electrocardiogram signal is further required based on at least one of information related to the first type of electrocardiogram signal or diagnostic information based on the first type of electrocardiogram signal.

[0019] Also, a user equipment for solving the above problem may include at least one processor; and a memory, wherein the at least one processor is configured to determine whether a second type of electrocardiogram signal different from the first type of electrocardiogram signal is further required; and to generate feedback information related to additionally measuring the second type of electrocardiogram signal.

[Effects of the Invention]

The above computing devices are merely examples, and the present disclosure is not limited thereto.

[0033] Data, as used in the detailed description of this disclosure and in the claims generally, can refer to material containing values ​​or information in any form, such as video, images, or text.

[0034] FIG. 1 is a block diagram of a computing device for directing additional electrocardiogram measurements, according to one embodiment of the present disclosure.

[0035] The configuration of the computing device (100) shown in Figure 1 is merely a simplified example. In one embodiment of the present disclosure, the computing device (100) may include other components for implementing the computing environment of the computing device (100), and the computing device (100) may be configured with only some of the disclosed components.

[0036] The computer device (100) may include a processor (110), a memory (130), and a network unit (150).

[0037] In one embodiment of the present disclosure, the processor 110 may be configured with one or more cores and may include processors for data analysis and deep learning, such as a computing central processing unit (CPU), a general-purpose graphics processing unit (GPGPU), and a tensor processing unit (TPU). The processor 110 may read a computer program stored in the memory 130 and execute data processing for machine learning in one embodiment of the present disclosure. According to one embodiment of the present disclosure, the processor 110 may perform calculations for neural network training. In deep learning (DL), the processor 110 may execute calculations for neural network training, such as processing input data for training, extracting features from the input data, calculating errors, and updating neural network weights using backpropagation. At least one of the CPU, GPGPU, and TPU of the processor 110 may process network function training. For example, a CPU and a GPGPU may both train a network function or classify data using the network function. In one embodiment of the present disclosure, processors of multiple computing devices may be used together to train a network function or classify data using the network function. In one embodiment of the present disclosure, a computer program executed on a computing device may be a program executable by a CPU, a GPGPU, or a TPU.

[0038] In one embodiment of the present disclosure, the memory 130 can store any type of information generated or determined by the processor 110 and any type of information received by the network unit 150.

[0039] In one embodiment of the present disclosure, the memory 130 may include at least one type of storage medium selected from the group consisting of flash memory, hard disk, micro multimedia card, card-type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk. The computing device 100 may also operate in conjunction with web storage that performs storage functions of the memory 130 over the Internet. The above descriptions of memory are merely examples, and the present disclosure is not limited thereto.

[0040] In the present disclosure, the network unit 150 can use any type of wired or wireless communication system.

[0041] The techniques described herein can be used in the above networks as well as other networks.

[0042] In one embodiment of the present disclosure, the processor 110 may perform operations to induce measurements of a second type of electrocardiogram signal in addition to a first type of electrocardiogram signal, where the first type of electrocardiogram signal may include a single-lead electrocardiogram signal or a limb lead electrocardiogram signal, and the second type of electrocardiogram signal may include a precordial electrocardiogram signal.

[0043] For example, the processor 110 may (1) perform an operation of acquiring a first type of electrocardiogram signal transmitted via the network unit 150, stored in the memory 130, or measured by a measurement unit unique to the computing device 100, and (2) perform an operation of determining whether a second type of electrocardiogram signal different from the first type of electrocardiogram signal is required based on at least one of information related to the first type of electrocardiogram signal or diagnostic information based on the first type of electrocardiogram signal. (3) If the processor 110 determines that a second type of electrocardiogram signal is required, the processor 110 may generate feedback information to guide the user to perform an additional measurement of the second type of electrocardiogram signal. The feedback information may be generated in various forms, including visual information, auditory information, etc. The computing device 100 may further include a visual output unit, such as a display device, or an auditory output unit, such as a speaker, for outputting such feedback information. In addition to these output units, the computing device 100 may also include various output units for conveying feedback information to a user. Furthermore, the computing device (100) can transmit this feedback information to an external device such as a smart device via the network unit (150), and can also output this feedback information via the external device.

[0044] FIG. 2 is a schematic diagram illustrating a network function in one embodiment of the present disclosure.

[0045] Throughout this specification, the terms computational model, neural network, network function, and neural network may be used interchangeably. A neural network is often composed of a collection of interconnected computational units, commonly called nodes. Such nodes may also be referred to as neurons. A neural network is composed of at least one or more nodes. The nodes (or neurons) that make up a neural network may be interconnected by one or more links.

[0046] In a neural network, one or more nodes connected via links can form a relative relationship between an input node and an output node. The concepts of input node and output node are relative, and any node that is an output node for one node can also be an input node for another node, and vice versa. As mentioned above, the relationship between input node and output node can be established around links. One or more output nodes can be connected to one input node via links, and vice versa.

[0047] In a relationship between an input node and an output node connected via a link, the value of the data in the output node can be determined based on the data input to the input node. Here, the node interconnecting the input node and the output node can have a weight. The weight can be variable and can be changed by a user or an algorithm so that the neural network performs a desired function. For example, if one or more input nodes are interconnected to one output node by each link, the output node can determine its value based on the value input to the input node connected to the output node and the weight set for the link corresponding to each input node.

[0048] As described above, a neural network has one or more nodes interconnected via one or more links, forming a relationship between an input node and an output node within the neural network. The characteristics of a neural network can be determined by the number of nodes and links, the correlation between the nodes and links, and the weights assigned to each link. For example, if two neural networks have the same number of nodes and links but different link weights, the two neural networks can be recognized as different.

[0049] A neural network can be composed of a set of one or more nodes. A subset of the nodes in a neural network can form a layer. Some of the nodes in a neural network can form a layer based on their distance from a first input node. For example, a set of nodes whose distance from a first input node is n can form n layers. The distance from the first input node can be defined based on the minimum number of links that must be traversed to reach that node from the first input node. However, this definition of a layer is arbitrary for the purpose of explanation, and the configuration of layers in a neural network can be defined in a manner different from the above description. For example, a layer of nodes can also be defined based on their distance from the final output node.

[0050] A first input node may refer to one or more nodes in a neural network to which data is directly input without passing through a link in relation to other nodes. Alternatively, a first input node may refer to a node in a neural network that does not have other input nodes connected via a link in relation to other nodes based on links. Similarly, a final output node may refer to one or more nodes in a neural network that do not have output nodes in relation to other nodes. Furthermore, a hidden node may refer to a node that is neither a first input node nor a final output node and that constitutes a neural network.

[0051] A neural network according to an embodiment of the present disclosure may be a neural network in which the number of nodes in the input layer is the same as the number of nodes in the output layer, and the number of nodes decreases once and then increases again as the network progresses from the input layer to the hidden layer. A neural network according to an embodiment of the present disclosure may be a neural network in which the number of nodes in the input layer is fewer than the number of nodes in the output layer, and the number of nodes decreases as the network progresses from the input layer to the hidden layer. Furthermore, a neural network according to another embodiment of the present disclosure may be a neural network in which the number of nodes in the input layer is greater than the number of nodes in the output layer, and the number of nodes increases as the network progresses from the input layer to the hidden layer. A neural network according to another embodiment of the present disclosure may be a neural network that combines the above-mentioned neural networks.

[0052] A deep neural network (DNN) can refer to a neural network that includes multiple hidden layers in addition to an input layer and an output layer. Deep neural networks can be used to understand the latent structures of data. That is, they can understand the latent structures of photos, text, video, audio, and music (e.g., whether a certain object appears in the photo, what the content and emotion of the text are, what the content and emotion of the audio are, etc.). Deep neural networks include convolutional neural networks (CNNs), recurrent neural networks (RNNs), autoencoders, generative adversarial networks (GANs), restricted Boltzmann machines (RBMs), deep belief networks (DBNs), Q-networks, U-networks, Siamese networks, and generative adversarial networks (GANs). The above-mentioned deep neural networks are merely examples and the present disclosure is not limited thereto.

[0053] In one embodiment of the present disclosure, the network function may include an autoencoder. An autoencoder may be a type of artificial neural network that outputs output data similar to input data. An autoencoder may include at least one hidden layer, and an odd number of hidden layers may be arranged between the input and output layers. The number of nodes in each layer may decrease from the number of nodes in the input layer toward an intermediate layer called a bottleneck layer (encoder), and may expand in a symmetrical manner from the bottleneck layer toward the output layer (symmetrical to the input layer). An autoencoder may perform nonlinear dimensionality reduction. The number of input and output layers may correspond to the dimensionality of the input data after preprocessing. In an autoencoder structure, the number of nodes in the hidden layer included in the encoder may decrease as the distance from the input data increases. If the number of nodes in the bottleneck layer (the layer with the fewest nodes located between the encoder and decoder) is too small, sufficient information may not be transmitted. Therefore, the number of nodes may be maintained above a certain number (e.g., more than half of the input layer).

[0054] Neural networks can be trained using at least one of supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning. Training a neural network can be a process of providing the neural network with knowledge that enables it to perform a specific operation. Neural networks can be trained in a direction that minimizes the error in the output. Training a neural network involves repeatedly inputting training data into the neural network, calculating the error between the neural network's output and the target for the training data, and backpropagating the neural network's error from the output layer to the input layer of the neural network to update the weights of each node in the neural network in a direction that reduces the error. In supervised learning, training data in which the correct answer is labeled is used for each individual piece of training data (i.e., labeled training data), while in unsupervised learning, the correct answer may not be labeled for each individual piece of training data.

[0055] For example, in supervised learning for data classification, training data can be data in which each training data is labeled with a category. The labeled training data is input to a neural network, and an error can be calculated by comparing the output (category) of the neural network with the label of the training data. As another example, in unsupervised learning for data classification, an error can be calculated by comparing the input training data with the output of the neural network.

[0056] FIG. 3 is a flow chart illustrating a method for guiding additional electrocardiogram measurements according to one embodiment of the present disclosure.

[0057] Referring to FIG. 3, a method for inducing additional electrocardiogram measurements may be performed by a computing device (100) and may include a step of acquiring a first type of electrocardiogram signal (S100), a step of determining whether a second type of electrocardiogram signal different from the first type of electrocardiogram signal is further required based on at least one of information related to the first type of electrocardiogram signal or diagnostic information based on the first type of electrocardiogram signal (S200), and a step of generating feedback information for inducing measurement of the second type of electrocardiogram signal if the second type of electrocardiogram signal is further required (S300).

[0058] An electrocardiogram (ECG) signal is a signal related to the action current and action potential difference accompanying the contraction of the heart, and can be a type of biosignal derived from electrical or magnetic biological signals. The ECG signal can be represented by a wavy line, and is usually displayed as multiple electrocardiogram curves using an electrocardiograph, and is very important in diagnosing the presence or absence of cardiac abnormalities.

[0059] The electrocardiogram signal has 10 electrodes and 12 lead signals that are combinations of the electrodes. The electrodes can include RA, LA, RL, LL, V1, V2, V3, V4, V5, and V6. The lead signals can include three standard limb leads, three augmented limb leads, and six precordial leads. The standard limb leads include leads I, II, and III, the augmented limb leads include aVR, aVL, and aVF, and the six precordial leads can include lead signals induced by chest electrodes V1, V2, V3, V4, V5, and V6. The lead signals are sometimes referred to as "leads" or "lead electrocardiogram signals."

[0060] Here, the first type of electrocardiogram signal may include a single-lead electrocardiogram signal or a limb-lead electrocardiogram signal. A single-lead electrocardiogram signal may be an electrocardiogram signal induced by only two electrodes, primarily measuring lead I, and may be easily measurable using a smartphone, smartwatch, portable patch, portable pad, other portable dedicated electrocardiogram measurement device, or a combination thereof. Therefore, in cases where an accurate diagnosis of arrhythmia is difficult with a single electrocardiogram test, measuring the single-lead electrocardiogram recorded during daily life can be very useful. Recording a patient's heartbeat during such activities can help diagnose arrhythmia and clarify the relationship between the patient's symptoms and arrhythmia, and can also provide information to determine the effectiveness of therapeutic drugs.

[0061] To measure standard limb leads, electrodes can be connected to both arms and one leg (mainly the left leg), including lead I (where the left and right arms are the anode and cathode), lead II (where one leg and the right arm are the anode and cathode, respectively), and lead III (where one leg and the left arm are the anode and cathode, respectively).

[0062] Meanwhile, the second type of electrocardiogram signal may include electrocardiogram signals from precordial leads, which, unlike the limb leads, allow observation of the direction and force of electrical flow in the heart from a left lateral view, and can complement the limb leads.

[0063] FIG. 4 is a flow chart for guiding additional electrocardiogram measurements based on disease type in one embodiment of the present disclosure.

[0064] 4, the step of determining whether the second type of electrocardiogram signal is further required (S200) may include a step of determining that the second type of electrocardiogram signal is further required (S290) if the diagnostic information based on the first type of electrocardiogram signal corresponds to a predetermined type of disease (S210). In particular, the predetermined type of disease may be a cardiac abnormality that is difficult to diagnose using only a single lead or limb leads.

[0065] Here, the predetermined type of disease may include diseases classified as being more sensitive in chest leads than in limb leads. For example, measuring chest leads for ischemic heart disease can improve diagnostic sensitivity and specificity compared to measuring only limb leads. Therefore, first, electrocardiograms are monitored using only the first type of electrocardiogram signal, which is relatively easy to use and includes a single lead or limb leads. If ischemic heart disease is suspected, the second type of electrocardiogram signal, which includes chest leads, can be further measured. This enables economical and continuous monitoring of ischemic heart disease and ensures diagnostic accuracy. Meanwhile, in this case, the step of determining whether or not the second type of electrocardiogram signal is further required (S200) may include a step of checking whether or not there is a correlation with ischemic heart disease, which is one of the predetermined types of diseases, in the diagnostic information based on the first type of electrocardiogram signal, and determining whether or not the second type of electrocardiogram signal is further required based on the checking result (S290). The step S290 may include the processor (110) analyzing the diagnostic information based on the first type of electrocardiogram signal, and determining that the second type of electrocardiogram signal is further required if ischemic heart disease is suspected.

[0066] The predetermined type of disease may include at least one disease classified as having different diagnostic methods for limb leads and chest leads. For example, left ventricular hypertrophy (LVH) is generally diagnosed by measuring chest leads, but it can also be diagnosed using limb leads. Therefore, electrocardiograms can be monitored using only the first type of electrocardiogram signal, which is relatively easy to use and includes a single lead or limb leads. If left ventricular hypertrophy is suspected, an additional second type of electrocardiogram signal including chest leads can be measured, enabling economical and continuous monitoring of left ventricular hypertrophy. Diagnostic accuracy can also be ensured by cross-validating the limb-lead-based diagnosis and the chest-lead-based diagnosis. The limb-lead-based diagnosis or the chest-lead-based diagnosis can be performed using a pre-trained artificial neural network diagnostic model or a rule-based method. Meanwhile, in this case, the step of determining whether or not the second type of electrocardiogram signal is further required (S200) may include a step of checking whether or not there is an association with left ventricular hypertrophy, which is one of the diseases classified as having different diagnostic methods for limb leads and chest leads, in the diagnostic information based on the first type of electrocardiogram signal, and determining whether or not the second type of electrocardiogram signal is further required based on the checking result (S290). The step S290 may include the processor (110) analyzing the diagnostic information based on the first type of electrocardiogram signal and determining that the second type of electrocardiogram signal is further required if left ventricular hypertrophy is suspected.

[0067] FIG. 5 is a flowchart for guiding additional electrocardiogram measurements based on a preset reference value (or cut-off value) in one embodiment of the present disclosure.

[0068] 5, the step of determining whether an additional second type of electrocardiogram signal is needed (S200) may include a step of determining that an additional second type of electrocardiogram signal is needed if the predicted value based on the first type of electrocardiogram signal is within a predetermined range from a reference value (or cut-off value) (S292). As an example, in a method of measuring the first type of electrocardiogram signal from a patient and comparing a predicted value calculated based on the electrocardiogram signal with a predetermined reference value (or cut-off value), waveform information related to the first type of electrocardiogram signal is acquired (S100), the predicted value calculated based on the waveform information related to the first type of electrocardiogram signal is set as a first predicted value, and a reference value (or cut-off value) for comparing with the first predicted value to provide information related to the risk of heart disease is set as the first reference value. In this case, in conventional methods, it is possible to provide information regarding the risk of heart disease based on a comparison between the first predicted value and the first reference value, but in the present disclosure, it is possible to compare the first predicted value with the first reference value (S220), and if the first predicted value is in the boundary region (or margin region) of the first reference value, it is determined that additional measurement of the second type of electrocardiogram is necessary (S292), and a signal to induce additional measurement of the second type of electrocardiogram is generated.

[0069] Specifically, in the boundary region (or margin region) of the first reference value, the lowest point of the region is set as the first-1 reference value, and the highest point of the region is set as the first-2 reference value. If the first reference value is less than the first-1 reference value, the processor 110 can determine (S291) that the risk of heart disease is normal and low. If the first reference value is equal to or greater than the first-1 reference value and less than the first-2 reference value, the processor 110 can determine (S292) that further second-type electrocardiogram signals are needed. If the first reference value is equal to or greater than the first-2 reference value, the processor 110 can determine (S293) that the risk of heart disease (e.g., cardiac arrest) is high. If the processor 110 determines that further second-type electrocardiogram signals are needed or that the risk of heart disease is high, the processor 110 can send a feedback signal to the user to further guide the user to take the second-type electrocardiogram.

[0070] The feedback signal can be sent to the user as a video / image, text information, or audio signal via a device connected directly to the computing device (100) or via a network.

[0071] In addition, in the present disclosure, a user can carry a device capable of measuring the first type of electrocardiogram signal, and if the device or an application embedded therein determines, based on the first type of electrocardiogram signal, that further measurement of the second type of electrocardiogram signal is necessary or that the user is at high risk for heart disease, the device or an application embedded therein can transmit data including the user's electrocardiogram information, personal identification information, or current location information to a server at a hospital or rescue organization.

[0072] FIG. 6 is a flowchart for guiding additional electrocardiogram measurements based on predicted differences between diagnostic information in one embodiment of the present disclosure.

[0073] In one embodiment of the present disclosure, the step (S200) of determining whether further electrocardiogram signals of the second type are needed may include a step (S230) of predicting a difference between "first diagnostic information" based on the first type electrocardiogram signal and "second diagnostic information" based on the first type electrocardiogram signal and the second type electrocardiogram signal; and a step (S290) of determining whether further electrocardiogram signals of the second type are needed based on the predicted difference.

[0074] Here, step S230 can be performed using a neural network model that receives the first type of electrocardiogram signal as input and predicts a difference between the first diagnostic information and the second diagnostic information. For example, step S230 can be performed using a neural network model (binary classification model) that, after receiving the first type of electrocardiogram signal, (i) outputs a true prediction value if the difference between the first diagnostic information and the second diagnostic information is predicted to be large (e.g., in a binary diagnosis such as positive / negative, the diagnoses are predicted to be different from each other, or in a quantitative diagnosis, the difference between diagnostic values ​​is predicted to exceed a predetermined threshold), and (ii) outputs a false prediction value if the difference between the first diagnostic information and the second diagnostic information is predicted to be small. In the above embodiment, step S290 can include a step of determining that the second type of electrocardiogram signal is further required if a true prediction value is generated in step S230. In other words, according to such an embodiment, when it is predicted that the difference between the first diagnostic information (e.g., diagnostic information based on a single or four-limb lead electrocardiogram signal) and the second diagnostic information (e.g., diagnostic information based on a 12-lead signal to which a chest lead electrocardiogram signal has been added) will be large, the user is prompted to additionally measure a second type of electrocardiogram signal (e.g., a chest lead electrocardiogram signal), thereby making it possible to prevent erroneous diagnostic information based on the first type of electrocardiogram signal (e.g., a single-lead electrocardiogram signal or a four-limb lead electrocardiogram signal) from being determined.

[0075] Meanwhile, the neural network model (binary classification model) that can be used in the above step S230 can be trained through an exemplary process including the following operations: (1) training a "first model that predicts diagnostic information based on a first type of electrocardiogram signal" and a "second model that predicts diagnostic information based on a first type of electrocardiogram signal and a second type of electrocardiogram signal," respectively; (2) inputting general electrocardiogram data into the first model and the second model, respectively, to make a prediction; (3) if the first model and the second model generate a predicted value with a large difference, extracting the data and labeling it as true, and if the first model and the second model generate a predicted value with a small difference, extracting the data and labeling it as false; and (4) training the neural network model (binary classification model) using the data labeled in this manner.

[0076] FIG. 7 is a flowchart for determining whether more electrocardiogram signals are needed based on quantitative electrocardiogram analysis information in one embodiment of the present disclosure.

[0077] Referring to FIG. 7, the step of determining whether further electrocardiogram signals of the second type are needed (S200) may include a step of determining that further electrocardiogram signals of the second type are needed (S290) if diagnostic information based on the first electrocardiogram signal is generated two or more times within a predetermined period (S110) and electrocardiogram problems are diagnosed more than a predetermined number of times based on the diagnostic information generated two or more times (S250).

[0078] For example, the processor (110) can use a neural network model that provides information for predicting or diagnosing the presence or absence of an electrocardiogram abnormality based on the first type of electrocardiogram signal (e.g., a single-lead electrocardiogram signal or a four-limb lead electrocardiogram signal) to perform N or more diagnoses (N is a natural number greater than or equal to 2) within a predetermined period (e.g., 1 hour, 12 hours, 1 day, etc.), and if K or more electrocardiogram problems (K is a natural number less than N) are diagnosed based on the diagnostic information generated N times, the processor (110) can guide the processor to perform additional measurements of the second type of electrocardiogram signal in order to guide a more precise diagnosis.

[0079] FIG. 8 is a flowchart for stimulating additional electrocardiogram measurements based on waveforms associated with multiple lead signals in one embodiment of the present disclosure.

[0080] Referring to FIG. 8, the step of determining whether or not the second type of electrocardiogram signal is further required (S200) includes the steps of extracting the waveform of each of the plurality of lead signals (310, 320) included in the first type of electrocardiogram signal, and determining whether or not the second type of electrocardiogram signal is further required (S290) based on the difference between the waveforms of the plurality of lead signals (310, 320).

[0081] Specifically, when P-QRS-T waveforms are extracted from Lead I (310) and Lead II (320), if there is a difference in the position, shape, or number of one or more of the extracted complexes, it is possible to suggest additional measurement using chest leads and determine whether a second type of ECG signal is required. In this case, the complex may include one or more of the PR interval, the QRS interval of the beat, the QT interval of the beat, or the R-peak position of the beat.

[0082] For example, the processor (110) can receive input of Lead I (310) and Lead II (320) signals from among the limb lead signals included in the first type electrocardiogram signal, set electrocardiogram coordinates for each signal, identify the p, q, r, s, and t coordinates of the beats therein, and generate waveform position information for multiple elements. Next, the processor (110) can perform a calculation to directly compare the waveform position information of Lead I with the waveform position information of Lead II, and if the value is equal to or greater than a set value, determine that an additional second type electrocardiogram signal is required.

[0083] Alternatively, the generated waveform position information can be used to derive values ​​of the PR interval, QRS interval, or QT interval, which are elements included in the signals of Lead I (310) and Lead II (320). If the difference in any one value of the PR interval, QRS interval, or QT interval of Lead I (310) and Lead II (320) is equal to or greater than a preset value, the processor 110 can determine that an additional second type of electrocardiogram signal is required.

[0084] As described above, when comparing the signals of Lead I (310) and Lead II (320) of the limb lead signals to automatically identify and notify whether chest leads are necessary, the limb lead signals can play a role of screening. As a result, the present disclosure can reduce the burden on medical staff, reduce the frequency with which chest lead signals need to be measured, and achieve the effect of enabling accurate monitoring of electrocardiogram signals.

[0085] Furthermore, in one embodiment of the present disclosure, the step of determining whether the second type of electrocardiogram signal is further required may include: (1) inputting the first type of electrocardiogram signal (e.g., a single-lead electrocardiogram signal or a four-limb lead electrocardiogram signal) into a first prediction model having a first reference value (or a first cut-off value) and predicting cardiovascular abnormalities to generate a predicted value; and (2) determining whether the second type of electrocardiogram signal (e.g., a chest lead electrocardiogram signal) is further required based on the generated predicted value.

[0086] In this case, the second type of electrocardiogram signal can be input to a second prediction model (e.g., a prediction model based on a 12-lead signal) that has a second reference value (or a second cut-off value) and predicts abnormalities in the cardiovascular system, and the second reference value can be set to be different from the first reference value.

[0087] The first and second reference values ​​may be set differently, taking sensitivity or specificity into consideration. For example, the first and second reference values ​​may be set differently so that the performance of the first prediction model has higher sensitivity than the second prediction model (e.g., if the sensitivity standard is 0.8-0.9, the first prediction model has a sensitivity of 0.9). In this case, the first prediction model may generate alarms for cardiovascular abnormalities more frequently than the second prediction model. This allows the first prediction model to be used as a means of early screening for diagnosing cardiovascular abnormalities. However, in this embodiment of the present disclosure, even if the first prediction model generates false positive alarms more frequently, a more accurate diagnosis can be achieved and fewer patients may be overlooked by prompting further measurement of the second type of electrocardiogram signal (e.g., chest lead electrocardiogram signal) for patients suspected of a particular disease.
