Wearable motion load detection device and method based on dynamic ECG

Abstract

The invention provides a wearable motion load detection device and method based on dynamic ECG. The device includes an ECG signal acquisition module, a signal conditioning module, a wireless communication module, a data storage module and a microprocessor. By collecting dynamic ECG signals of a user, the signals are filtered, amplified and subjected to AD conversion; ECG digital signal informationis transmitted to a user client; then the signal analysis process including signal filtering, R-wave feature detection, eigenvector calculation, vector normalization and exercise load detection is completed; and finally, a detection report is generated and sent to a monitoring center. The device is easy and comfortable to wear, and can achieves the functions of collecting the user dynamic ECG signals for a long time, processing the dynamic ECG signals in real time, accurately detecting the user motion load and giving corresponding suggestions.

Description

technical field [0001] The invention belongs to the field of real-time monitoring of heart health during human exercise, and in particular relates to a wearable dynamic ECG-based exercise load detection device and a corresponding detection method. Background technique [0002] Exercise at a reasonable intensity will reduce the occurrence of diseases and contribute to good health, but if you exercise excessively, it will cause sports injuries to the body, especially for people with heart disease. Statistics show that 82% of non-traumatic sudden death is related to improper exercise in people with heart disease, so scientific fitness is very important. [0003] In 1973, Swedish physiologist Gunnar Bog designed the subjective physical sensation rating scale based on psychological principles on the rating scale of self-perception and actual exercise load. However, this method of assessment is inaccurate and not applicable to the general population. With the development of exer...

Problems solved by technology

In recent years, the technology of wearable ECG equipment has developed rapidly, and many wearable ECG monitoring products have appeared on the market. Although there are many ways to use heart rate to give exercise advice, they are basically based on the optimal heart rate. The algorithm evolved, and no further in-depth analysis of dynamic ECG was performed to judge individual exercise conditions from a multi-dimensional perspective, forming a complete exercise load monitoring method, so it does not have much application reference value
