Design of the Athlete´s Electrocardiogram Monitoring and Evaluation System Based on Wireless Sensor Network

A wireless ECG monitoring system suitable for the usage of athlete training and evaluation is proposed, which contains multiple client-side wireless ECG acquisition sub-systems based on MSP430, a central monitoring sub-system based on ARM and ECG analysis software on PC. The whole monitoring system constitutes a wireless sensor network with nRF905 wireless transceivers. The design of client-side system is simplified to the greatest extent to fit for the requirement of athlete training, which has the advantages of miniaturization, low power consumption, anti-interference and convenience for use. The central monitoring system is capable of real-time display, storing ECG data from multiple client-side systems, basic data analysis and warning signal promoting to monitor athletes´ physical status during training. ECG data can also be uploaded to PC to perform sophisticated analyses. In addition to conventional ECG analyses, the analysis system of heart rate variability is specially designed for the functional evaluation of autonomous neural system.
