Design of Holter ECG System Based on MSP430 and USB Technology

A new design method of integrated Holter electrocardiograph (ECG) system is put forward in the paper. The Holter ECG system is based on an excellent ECG signal sampling filter amplifier system , MSP430 16 bits ultra low power microprogrammed control unit (MCU) and SL811HS universal serial bus (USB) controller module. The Holter ECG uses bulk Flash memory HY27US16561M to record the ECG signal. The ECG signal recorded can be sent to the monitoring center through USB flash disk by the SL811HS USB controller. This Holter ECG can work stably and dependably for more than 24 hours, and with some excellencies such as ease of use, mini volume, bulk memory, low power, etc. It is convenient to be taken with and used.
