Abstract: This paper proposes a design of portable Electrocardiogram(ECG) monitor based on 32 bit embedded technology. The monitor equips an ARM920T-based microprocessor EP9315 as its main controller, and contains many other components such as ECG amplifiers, AD convertors, LCD display with touchscreen, GPRS module, and data storage device. It utilizes the Linux operating system and Qt/Embedded GUI, and has stable performance and friendly operating interface. The instrument realizes the acquisition, storage, display, automatic analysis and network transmission of human ECG signals.
