Problems solved by technology

However, in the continuous ECG (Electrocardiogram, electrocardiogram) monitoring process, the ECG record is as long as 24-48h, and contains 100,000-200,000 heartbeats. Cardiologists must spend a lot of time on heartbeat annotations, wasting a lot of time, and Labeling efficiency is not high

Embodiment 1

[0050] Figure 1A It is a flow chart of a method for labeling ECG records provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of labeling abnormal types of ECG records. Execution, the device can be implemented by software and / or hardware, and is usually configured in computer equipment. Such as Figure 1A As shown, the method specifically includes the following steps:

[0051] S101. Obtain an electrocardiographic record, where the electrocardiographic record includes a plurality of cardiac beat signals.

[0052] Specifically, before and after the heart beats, the myocardium is excited. In the process of myocardial stimulation, a weak biological current will be generated. In this way, every cardiac cycle of the heart is accompanied by bioelectrical changes. This bioelectrical change can be transmitted to various parts of the body surface. Due to the different tissues of different parts of the body and the different distances fro...

Embodiment 2

[0073] Embodiment 2 of the present invention provides a method for labeling ECG records, Figure 2A It is a flow chart of a method for labeling ECG records provided by Embodiment 2 of the present invention. This embodiment refines the basis of Embodiment 1 above, and describes the processing process of the abnormal ECG detection model in detail, as shown in Figure 2A As shown, the method includes:

[0074] S201. Obtain an electrocardiographic record, where the electrocardiographic record includes a plurality of cardiac beat signals.

[0075] Exemplarily, in some embodiments of the present invention, step S201 may include the following steps:

[0076] Acquire an electrocardiogram (ECG) signal. The electrocardiogram signal can come from the results of physical examination. The electrical signals of different parts of the body surface are detected through electrodes, and the collected signals are processed by impedance matching, filtering, and amplification through analog circ...

Embodiment 3

[0163] image 3 A method for training an abnormal ECG detection model provided by Embodiment 3 of the present invention. This embodiment can be used for the training of the abnormal ECG detection model provided by the above-mentioned embodiments of the present invention. The detection model training device is implemented, and the device can be implemented by software and / or hardware, and is usually configured in a computer device. Such as image 3 As shown, the method specifically includes the following steps:

[0164] S301. Obtain an electrocardiographic signal sample. The electrocardiographic signal sample includes a plurality of cardiac beat signal samples. The electrocardiographic signal sample is associated with a type label, and the type label is used to identify an abnormal type of the electrocardiographic signal sample.

[0165]Specifically, the ECG record sample is the ECG record used to train the abnormal ECG detection model, and the ECG record sample can be obtain...

Abstract

The invention discloses an electrocardio record labeling method and device, equipment and a storage medium. The method comprises the following steps: acquiring an electrocardio record, wherein the electrocardio record comprises a plurality of heartbeat signals; determining an electrocardio anomaly detection model; inputting the electrocardio record into an electrocardio anomaly detection model forprocessing to obtain a probability matrix that the heartbeat signal is of each anomaly type; calculating the sum of probability matrixes of all the heartbeat signals in a preset adjacent threshold ofeach heartbeat signal to obtain a plurality of intermediate matrixes; and marking the electrocardio record as the abnormal type of the heartbeat signal corresponding to a target value, wherein the target value is the maximum value in the plurality of intermediate matrixes. According to the method provided by the embodiment of the invention, the annotation of the record level is realized instead of annotating each heartbeat, so that the annotation efficiency is improved, and the time cost is saved. In addition, the relevance of all the heartbeat signals in the preset adjacent threshold of eachheartbeat signal in the electrocardio record is fully utilized, and the accuracy of subsequent electrocardio record labeling is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electrocardiographic signal processing, and in particular, to a method, device, device, and storage medium for labeling electrocardiographic records. Background technique [0002] A variety of diseases can cause ECG abnormalities, and the detection of ECG abnormalities is particularly important for the diagnosis of heart diseases. ECG diagnosis has become an indispensable part of clinical diagnosis. [0003] Existing ECG abnormality detection techniques require trained cardiologists to label each beat signal with beat annotations. However, in the continuous ECG (Electrocardiogram, electrocardiogram) monitoring process, the ECG record is as long as 24-48h, and contains 100,000-200,000 heartbeats. Cardiologists must spend a lot of time on heartbeat annotations, wasting a lot of time, and Labeling is not efficient. Contents of the invention [0004] The present invention provides a ...
