摘　　要：心电图在临床诊断心脏疾病中起着极其重要的作用,随着人们生活水平的提高,保健意识的增强,对便携式心电监护仪的需求也越来越大。文中设计了基于C8051F340的便携式心电信号采集系统,按照系统设计原则,提出了系统总体结构及功能,并采用余弦离散变换DCT对心电数据进行压缩,方便了数据存储和传输。ECG plays an important role in the clinical diagnosis of heart disease. With the rising of people＇ s living standard and the strengtheming of their health awareness, the needs for portable ECG minitors is becoming greater. This paper introduces the design of the portable acquisition system of electrocardio - signal based on C8051 F340, puts forward the overall structure and function of the system according to the design principle of it, and uses the portable acquisition system of electrocardio - signal to compress ECG data. In this way, it is convienient to store and transmit the data.
