ABSTRACT
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.
