Embodiment 1

[0020] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for removing ECG artifact signals, comprising the following steps:

[0021] S1. Collect original ECG signals, and identify feature points on the original ECG signals;

[0022] S2. Perform fitting according to the feature points to obtain an artifact signal, and subtract the artifact signal from the original ECG signal to obtain an artifact-free ECG signal;

[0023] S3, judging whether the quality parameter of the ECG signal after artifact removal meets the preset condition, if yes, then turn to S4, otherwise correct the feature points, and then turn to S2;

[0024] S4. The original ECG signal is used as input, and the artifact-removed ECG signal is used as a label, and sent to the neural network for training to obtain an artifact removal model;

[0025] S5. Perform artifact removal on the ECG signal to be processed according to the artifact removal model.

[0026] This embodiment will ...

Embodiment 2

[0073] Embodiment 2 of the present invention provides an electrocardiographic artifact signal removal device, including a processor and a memory, and a computer program is stored in the memory, and when the computer program is executed by the processor, the heart signal provided by Embodiment 1 is realized Electro-artifact signal removal method.

[0074] The electrocardiographic artifact signal removal device provided by the embodiments of the present invention is used to realize the electrocardiographic artifact signal removal method. Therefore, the electrocardiographic artifact signal removal device also possesses the technical effects of the electrocardiographic artifact signal removal method, I won't repeat them here.

Abstract

The invention relates to the technical field of electrocardio signal processing, and discloses an electrocardio artifact signal removing method. The method comprises the following steps: S1, collecting an original electrocardio signal, and identifying feature points on the original electrocardio signal; S2, performing fitting according to the feature points to obtain an artifact signal, and subtracting the artifact signal from the original electrocardiosignal to obtain an artifact-removed electrocardiosignal; S3, judging whether the quality parameter of the electrocardiosignal subjected to artifact removal meets a preset condition or not, if so, turning to S4, otherwise, correcting the feature points, and then turning to S2; S4, taking the original electrocardiosignal as an input, taking the electrocardiosignal after artifact removal as a label, and sending the label to a neural network for training to obtain an artifact removal model; and S5, performing artifact removal on the to-be-processed electrocardiosignal according to the artifact removal model. The method has the technical effects that signal distortion cannot be caused after artifacts are removed, and the artifact removing precision is high.

Description

technical field [0001] The invention relates to the technical field of electrocardiographic signal processing, in particular to a method, device and computer storage medium for removing electrocardiographic artifact signals. Background technique [0002] The motion artifacts in the ECG signal directly affect the readability of the ECG report and the doctor's diagnosis due to the large variation range and large frequency span range. It is technically difficult to remove the motion artifact in the ECG signal because the motion artifact in the ECG signal overlaps with the effective ECG signal in the frequency domain. [0003] Common methods for removing motion artifacts in ECG signals include: [0004] Frequency Domain Filtering Method. A filter is designed to remove the low-frequency motion artifact signal. This method will also remove the corresponding frequency band in the normal ECG signal, making the processed ECG signal distorted. Especially for the PQ segment and ST s...
