Abstract: ECG machine is a important device to obtain important information on the work of the human heart. With the development of technology, ECG monitoring equipment is moving towards miniaturization, intelligence, home of direction. In this paper, design a sound card ECG monitoring virtual instrument based on USB sound card or a laptop as a virtual instrument
platform. The main work includes ECG front-end signal acquisition and communication circuit design, software development, ECG monitoring function. Using the hardware and software measures to effectively suppress the noise power and the environment, under the RLD to achieve a real-time ECG signal acquisition mode, noise analysis, display and other functions. The entire electrical system security for individual test performance and stability, in line with the actual monitoring results for individuals and families everyday applications.
Key words: Virtual Instruments; ECG; USB Sound card;Anti-jamming
