摘要：

In this paper, a portable low-cost long- time one lead Electrocardiogram (ECG) Monitor is present, which is powered by one dry battery and based on NUC501. Power management module, analogous amplifier and Advanced RISC Machines (ARM) are used in hardware design. While hardware driver, digital filter, modified baseline drift method and difference threshold method are taken in software structure. The monitor gathers ECG signal through cable from user's body. A prototype instrument has been finally produced and will be put into the clinical environment. The notch filter and median filter are used to process the data. His/her ECG tracing is displayed lively on Liquid Crystal Display (LCD) screen. Also the heart rate is shown precisely on LCD screen and displayed with led flashing. The monitor also can storage and transport data to computer through Universal Serial Bus (USB) cable. While being powered by one dry battery, it works twenty-four hours. If there is any abnormally changes of heart rate, this instrument will be given alarm through the buzzer. The testing results show that this monitor is low power consumption, light-weight, accurate and low-cost. It can care for cardiac patients very good and provide a reliable cost-effective choice for cardio-path.
