摘　　要：目的:研究基于Labview的心电信号关联维数的快速实现方法。方法:以PCI-6023E板卡作为硬件,以图形化编程语言LabVIEW为开发软件,实现心电信号的采集、显示和处理,并通过软件编程实现心电信号关联维数的快速计算。结果:对冠心病患者和健康人的心电信号关联维数进行分析计算,可以快速计算出关联维数,冠心病患者的关联维数要明显低于正常人。结论:基于Labview的心电信号关联维数系统,实现心电信号的关联维数的快速计算,解决从心电信号中提取心率变异(HRV)信息较难以及提取到有用信息不足的问题,为临床诊断和治疗提供重要的参考信息。Objective:To research a fast-implementation method of correlation dimension of ECG signal base on LabVIEW.Methods:In this paper,acquisition,display and processing of ECG signal were implemented through applied PCI-6023E as hardware and applied graphical programming language LabVIEW as development software.And then through software programming to realize fast calculation for correlation dimension of ECG signal.Results:This method was used to analyze and calculate the correlation dimension of ECG between patients with coronary heart disease and healthy people.And the experiment indicated that it can fast and reliably calculate the correlation dimension,and the correlation dimension of patients with coronary heart disease was obviously lower than that of healthy people.Conclusion:The correlation dimension system of ECG signal based on LabVIEW can realize the fast calculation of correlation dimension of ECG signal,and solve the two problems that heart rate variability(HRV)information are difficultly extracted from ECG signal and the extracted useful information are inadequate.Therefore,it provides important reference information for clinical diagnosis and treatment.
