Design For Remote Diagnosing System Of ECG On Virtual Instrument

Although heart disease has already posed a great threat to human health， the detection andanalysis of ECG constitutes the primary means to correctly diagnose such diseases. This paper，based on the analysis of ECG signal detection technology and virtual instrument technology，designs a set of ECG remote diagnosing system by using LabVIEW virtual instrument softwaredevelopment tools.The system this subject has designed mainly include six modules: ECG signal reading, ECGsignal preprocessing, feature points extraction, ECG signal diagnosing, ECG signal databaseestablished and remote diagnosing.This paper emphatically expounds ECG signal analysis andprocessing parts, and by means of researching ECG time-domain and frequency-domain featuresand medical knowledge, we focus on application of time-domain and frequency-domaininterpolation, IIRfilter design, wavelet analysis, noise treatment, spectral analysis and othermodern digital signal processing technology, and then this paper also applied to database andnetwork programming.Based on LabVIEW development platform, the system can complete datareading, data analysis, data diagnosing and result showing.Finally the experimental results showed that the designed scheme of this system isreasonable, and this system could offer help for ECG diagnosing.In particular, the problem thathow to remove the interference and noise of ECG signal has been solved well and the system canrapidly generate the result. Moreover, the system designed is highly human-machine interactiveand user-friendly and can be called by IE that can achieve remote diagnosing and promoteeffectiveness of heart disease diagnosing.
