A ECG monitoring system with ECG signal denoising function

Abstract

The invention discloses an electrocardiogram monitoring system with an electrocardiogram signal denoising function, which comprises a three-axis acceleration sensor, an electrocardiogram monitor and an intelligent terminal. The present invention uses a three-axis acceleration sensor to collect motion data as a neural network input sample, preprocesses the dynamic ECG data when the human body is still and in motion through format conversion and normalization methods, and makes the difference between the two The deviation is used as the supervision of the neural network, and then the artificial neural network learning algorithm is used to establish the noise model with the optimization method of proportional conjugate gradient, and the denoising is completed by subtracting the corresponding motion noise from the monitored Holter data. The whole system is simple and easy to implement. It can effectively and automatically remove vehicle motion noise during ECG monitoring, obtain accurate ECG data, and provide guarantee for doctors to diagnose and treat cardiovascular diseases.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an electrocardiogram monitoring system with an electrocardiogram signal denoising function. Background technique [0002] Dynamic electrocardiogram is used to continuously record 24-hour dynamic electrocardiographic activity data, including electrocardiographic activity data under different conditions such as rest, activity, work, and meal, which can help to find symptoms such as arrhythmia and myocardial ischemia, and provide clinical analysis and provide an important basis for diagnosis and treatment. With the emergence of portable and wearable ECG monitoring devices, users can perform very convenient ECG monitoring in various states. However, dynamic ECG signals are easily interfered by various noises. The main disturbances include AC interference, EMG interference, baseline drift, wrong connection of lead wires, insufficient contact between electrode pa...

Problems solved by technology

[0005] At present, most of the portable Holter monitors on the market have a simple structure and do not have the function of eliminating vehicle motion noise. When used in the state of vehicle motion, they are easily disturbed and the Holter signal is unstable. The recorded ECG waveform cannot be used for ECG analysis. It not only limits the scope of use of dynamic ECG monitoring equipment, but also may cause serious consequences for doctors in the diagnosis and treatment of patients with cardiovascular diseases
