Embodiment 1

[0023] Embodiment 1 Myocardial infarction automatic detection method based on lead fusion deep neural network

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] A specific example is the PTB Diagnostic ECG Database (ptbdb), an internationally accepted electrocardiogram database. The data and usage instructions of this database are published on the well-known physiionet.org website in the industry. The database contains ECG data of 15 leads of 294 patients or volunteers, including conventional 12 leads and 3 Frank leads, and here only 12 conventional leads are selected. Electrical signal data for testing. For downloading the data on the physiionet.org website, by the way, it is classified according to the marked disease types. Here we only discuss the two conditions of health and myocardial infarction. The labels of the two categories and the corresponding relationship with the categor...

Abstract

The invention discloses an automatic detection method of myocardial infarction based on lead fusion deep neural network. The automatic detection method includes the following steps: 1) generating 12-lead ECG signal samples by intercepting a single heart beat; 2) building a 12-lead ECG signal cnvolutional neural network model; 3) training parameters of the convolutional neural network; and (4) carrying out automatic recognition on test set samples; and inputting the divided test set samples into the convolutional neural network and carrying out running to obtain the 2-dimensional predicted value vector output corresponding to the test set samples, generating the 2-dimensional label vector using the one-hot coding method for labels of the test set samples, comparing the output predicted values with the labels of the test set samples to check the correctness of the classification, and judging the performance of the model by the classification result y_pred. The method achieves relativelyhigh accuracy in the recognition of multi-lead ECG signals. furthermore, the accuracy of the method in the recognition of heart beat for myocardial infarction can reach 99.51%.

Description

technical field [0001] The invention relates to the technical field of medical signal processing, more precisely, an automatic detection method for myocardial infarction based on a lead fusion deep neural network. Background technique [0002] With the development of digital technology, computer-aided diagnosis system has become the most promising solution for clinical diagnosis due to its fast and reliable analysis means. Today, through advanced hardware facilities, it is easy to obtain the patient's ECG signal, which is also known as the ECG. Physicians can judge the patient's state by observing the information contained in the ECG, however, the process of manually or visually inferring these subtle morphological changes in long continuous ECG beats is time-consuming and prone to errors due to fatigue. Therefore, real-time computer-aided diagnosis systems are essential to help physicians monitor patients' conditions in real time and overcome these limitations in the evalu...
