Wearable electrocardiosignal monitoring device and method

Abstract

The invention provides a wearable electrocardiosignal monitoring and processing method and device. Flexible fabric electrocardioelectrodes and a central control box are embedded into an elastic chest belt. The central controller comprises an electrocardiosignal collecting and conditioning unit, a signal processing unit, a data storage unit, a power unit and a wireless communication unit. The signal processing unit carries out filtering, feature extraction and analysis of the heart abnormal change state on the electrocardiosignal collected, amplified and filtered preliminarily by the collecting and conditioning unit. The signal waveform and the analysis result are sent to personal digital management equipment like a mobile phone of a user through the wireless communication unit and can be sent to a remote doctor through a network, and the doctor analyzes the illness state and feeds back medical suggestions and matters needing attentions to the user. The wearable electrocardiosignal monitoring device has the advantages of being comfortable to wear, light, small in size, low in cost and the like, long-term monitoring is facilitated under the conditions of daily life, study, activities and the like, and the intelligent diagnosis and feedback treatment of the heart state are achieved.

Description

technical field [0001] The present invention relates to the technical field of wearable health care, in particular to a wearable electrocardiogram signal monitoring and processing method and device. Background technique [0002] In recent years, with the increasing prevalence of chronic diseases, including cardiovascular disease, among the elderly, and with the characteristics of complex etiology and disease, long illness time, high medical costs, and long-term management, more and more Many patients expect to change the health monitoring model from hospital-centered to family-centered, and to curb the rapidly rising trend of chronic diseases in the elderly through personal health management, thereby reducing the medical economic burden. The very important ECG signal is of great significance in the monitoring and diagnosis of heart disease and other chronic diseases. It is one of the earliest bioelectric signals studied and applied in medical clinics. Dynamic ECG is an impo...

AI Technical Summary

Problems solved by technology

[0004] Although the above patents are based on wearable technology using flexible fabric electrodes, which can successfully achieve the purpose of long-term monitoring of ECG signals, fabric electrodes are relatively complicated to manufacture, and even require manufacturing equipment to complete. At the same time, fabric electrodes are not considered. Detection of ECG in the case of human activity will bring a lot of motion artifact interference

Unlike other interferences with a specific frequency range, it has a dynamic frequency range and a large amplitude, which can easily damage or drown biological signals, which will lead to unreasonable processing and wrong diagnosis, and bring great challenges to monitoring

Motion artifacts can largely interfere with the validity of the ECG signal, potentially leading to incorrect evaluation of ECG signal parameters and triggering of false alarms
