Objective: To design a ECG signal research system, which is an important part of the development of remote ECG monitor. Methods: Firstly, a hardware platform was built with high-performance PC and high-performance DA converter. Then, Visual C ++ 6.0 was used as a platform to build MIT-BIH electrocardiogram database using object-oriented programming language. Results: The system can manage and playback ECG and respiratory data in MIT-BIH ECG database and establish experimental data platform to generate simulated ECG, respiration and other physiological signals, which can be used to develop remote ECG monitoring instruments use. Conclusion: It can provide an excellent research platform for the future research and analysis of ECG signals and the development of related instruments.
