Embodiment 1

[0026] refer to figure 1 As shown, a schematic structural diagram of an ECG-based glycosylated hemoglobin detection system provided in the embodiment of this specification, the detection system may include: ECG signal acquisition module 1, ECG signal preprocessing module 2, feature extraction and identification module 3 , The result display module 4.

[0027] Wherein, the ECG signal acquisition module 1 acquires the patient's ECG signal through a non-invasive sensing method, and the specific implementation steps are as follows:

[0028] Step 101, the patient wears an ECG signal collector, and the ECG signal collector adopts a one-channel three-electrode acquisition mode.

[0029] Optionally, the three electrodes can be placed on the left ankle, right ankle, and left wrist respectively; they can also be placed on the patient's chest, arms and other parts.

[0030] Step 102, after the three electrodes are worn, activate the ECG signal acquisition module 1 to start automatic si...

Embodiment 2

[0073] An ECG-based detection method for glycosylated hemoglobin provided in the embodiment of this specification includes the following steps:

[0074] Step 1. Acquisition of ECG signals. Acquire ECG signals of patients through non-invasive sensing methods.

[0075] Step 2, preprocessing the electrocardiographic signal, judging whether the quality of the acquired electrocardiographic signal meets the requirements, the method of judging is an autocorrelation analysis method;

[0076] Step 3, feature extraction and identification, extract the features of ECG signals by deep learning method, and realize the identification of glycated hemoglobin level according to the features of ECG signals;

[0077] Step 4. The results are displayed. The displayed content includes the results of ECG signal collection and the prediction results of the HbA1c level. When the ECG signal collection is incorrect or incomplete, the patient will be prompted to re-collect immediately; when the predicted...

Abstract

The embodiment of the invention aims to provide an electrocardio-based glycosylated hemoglobin detection method and system. According to the invention, self-correlation calculation is carried out on electrocardio signals to judge the electrocardio quality, feature extraction of the electrocardio signals and output of pre-classification results are achieved through a convolutional neural network, category weights are automatically adapted, therefore, the level of the glycosylated hemoglobin is calculated, the detection of the level of the glycosylated hemoglobin is realized, and a non-invasive, rapid and low-cost glycosylated hemoglobin detection scheme is provided for a patient.

Description

technical field [0001] The invention belongs to the technical field of medical care and health, and in particular relates to an electrocardiogram-based glycosylated hemoglobin detection system and method. Background technique [0002] Glycosylated hemoglobin is a stable compound formed by combining some special molecular parts of hemoglobin and glucose through a slow and irreversible reaction. , whether to use insulin and other factors have nothing to do. [0003] Glycosylated hemoglobin can be used to evaluate the effect of blood sugar control in diabetic patients, and it is also an effective indicator for evaluating blood sugar management treatment plans. Glycosylated hemoglobin is also the preferred diagnostic indicator for diabetes recommended by the World Health Organization and many national diabetes societies. Compared with traditional diabetes diagnostic indicators, glycosylated hemoglobin has small biological variability and is not easily affected by blood sugar f...
