摘要用来记录病人心电图的活动的心电图仪，对人体的生物信号的测量，可用于诊断心肌梗死，心律失常和其它心血管疾病。目前，国内各大医疗设备制造商和研究机构正在开发的心电图已经投入了大量的资源，而且已经开发出一种独特的ECG产品，但这样的心电图并没有得到很好的普及，究其原因，笔者认为有有以下几种：体积大，携带不方便，很难及时监控的状态下工作，但这些心电图产品的价格都非常昂贵，只有医院的实力才有能力购买。对医疗规模有限机构或个人来说是一个沉重的负担，因此没有得到很好的推广。
本课题主要利用单片机系统，模电数电知识，传感器技术等知识设计一个简易心电图仪，要求示波器上显示测量的人体的心电信号，并要求单片机具有存储、回放波形的功能。[ ]
在本课题的软件设计中，是以Keil uVision4为仿真平台，系统应用软件由C语言进行的编码。通过在proteus 软件中仿真，在结果中可以看到本系统的功能和指标达到了设计要求。在系统的硬件件设计中，使用multisim10.0为设计平台，进行放大模块和滤波模块的仿真。21579

Title Simple Electrocardiograph Instrument
Abstract
ECG instrument used to record the electrocardiogram of patients with active, measurement of human biological signals, can be used for the diagnosis of myocardial infarction, arrhythmia and other cardiovascular diseases. At present, the ECG domestic major medical equipment manufacturers and research institutes are developing has invested a lot of resources, but also has developed a unique ECG products, but such ECG did not get very good popularizing large volume, inconvenient to carry, very difficult to monitor the state of work, but these ECG product prices are very expensive, and only the strength of the hospital have the ability to purchase.
This paper mainly uses the single chip system, sensor technology, electronic circuit design technology, the design of interface circuit of a simple ECG I/O keyboard and display, can measure the ECG signal and the oscilloscope, and stored, playback function measured.
In the design of software system, using Keil C51 as the simulation platform, the use of C language, the application software of the system. Through the simulation in Proteus Software, the result shows that the system functions and performance meet the design requirements. In the system hardware design, the use of Multisim10.0 as design platform, the simulation of the amplifier.
