 Abstract In modern society, heart disease has been a serious threat to people's health and lives. The main problem in medicine, engineering is how to detect, diagnose, ECG and heart disease prevention. The heart rate monitoring system can detect the heart rate in real time, when detecting abnormal heart rhythms, take the appropriate first aid and therapeutic measures to reduce the incidence of heart disease occurs due to lack of timely treatment and death effectively reduced mortality. Therefore, the design of a reliable ECG monitoring system is important for patients with heart disease is.
Multifunctional heart rate signal acquisition system for monitoring ECG characteristics for ECG signal acquisition, conditioning design and development. The system mainly uses three lead ECG signal acquisition acquisition method, starting from the ECG signal processing design reliable ECG conditioning circuit, ECG input MSP430 microcontroller A / D conversion and data processing, the next crew Heart rate data display, remote transmission, more alarm and PC management platform LabVIEW online monitoring, and other functions to save the information.
Lower computer hardware circuit can be designed to achieve stable ECG data acquisition, data processing and remote transmission function, PC software enables ECG data display and processing, to achieve the purpose of monitoring the heart rate signal acquisition, suitable for indoor and outdoor two scenarios for easy home use.
