Wearable Body Surface Potential Acquisition Device Based on Distance Segment Weighting Algorithm

Abstract

The invention discloses a wearable body surface potential acquisition device and method based on a distance segmentation weighting algorithm. After the user puts on the device, the dry electrodes distributed on the vest collect the user's body surface potential and connect it to the analog front end and send it to the analog front end. into the data acquisition system, and the data acquisition system is connected to the PC. The signals received by some of the dry electrodes are used as electrocardiographic signals to synthesize electrocardiograms. If the corresponding lead signal is good, it will be adopted directly; if the corresponding lead signal is not good, four different multi-lead algorithms will be used to obtain the corresponding ECG. According to the similarity, a weighted algorithm based on distance is used to select the algorithm that can best represent the user's ECG from the four algorithms. The health status of the user is analyzed according to the obtained electrocardiogram, and at the same time, the distribution of lesions can be determined according to the body surface potential mapping (BSPM) to guide subsequent treatment.

Description

technical field [0001] The invention relates to a body surface potential acquisition technology, in particular to a wearable body surface potential acquisition device and method based on a distance segmentation weighting algorithm. Background technique [0002] With the improvement of people's living standards and changes in lifestyle, the incidence of cardiovascular disease is also increasing year by year, and its high disability rate, high rehospitalization rate and high mortality rate have caused a huge burden on the quality of life of patients and social development. At present, there are estimated to be 290 million patients with cardiovascular diseases in the country, and their case fatality rate is 2.5% to 3.0%, accounting for more than 40% of the death of Chinese residents. The high mortality rate, high disability rate, high medical risk and high medical burden of cardiovascular and cerebrovascular diseases make it a major social problem. The monitoring of various si...

Problems solved by technology

[0003] Although the invention with the application number CN201710262618.9 can monitor the patient's ECG in real time, the monitoring of the ECG is still not accurate enough and is greatly affected by the user's movement

It is impossible to perform further analysis and diagnosis on the patient, nor can it analyze the location of the user's heart disease

[0004] The invention with the application number CN201711309089.X monitors the health of the human body through the body's bowel sounds, heartbeat, breathing, body temperature, blood oxygen, etc., only the most basic monitoring is carried out, which is too general

For the increasingly common cardiovascular and cerebrovascular diseases, the effect of early detection and prevention cannot be achieved.
