Design of Portable Wireless Electrocardiogram Monitoring System

Abstract

Cardiovascular disease is a major disease that seriously threat to people's health and life. And such diseases often have unexpected features. If it can't be timely detected and treated, it will have very serious consequence. So on cardiovascular disease in care becomes particularly important. This thesis investigate an ECG Monitoring System that based on a wireless transmission technology. The system contains three parts: ECG pretreatment, wireless transmission and central control. The ECG signal that from ECG collection device be pretreatment and by microcomputer control to complete A/D conversion, then wireless transmission chip nRF905 will send out the signals; wireless transmission chip nRF905 will receive the signal and transmitted to PC for analysis, complete ECG guardianship. The design is aimed at using wireless transmission to replace cable transmission, enable patients in free activities at the same time by the guardianship, it is also the innovation of this thesis. This thesis describes the design of the ECG monitor with portability and low power consumption advantages.
