摘要
文中采用LabVIEW技术在频域对心率变异信号进行功率谱分析,实现了三维频谱显示图。通过实验检验了心电信号采集、检测和谱分析方法的可靠性。因此,LabVIEW技术对HRV分析是有效的,可用于检测自主神经系统功能的平衡状态。
This paper gives a general introduction to power spectrum density analysis of heart rate variability in frequency domain with LabVIEW techniques. The HRV analysis in frequency domain consists of 3-dimensional frequency chart. The experiment results of HRV spectral analysis have shown that our method of analysis is correct. So based-LabVIEW HRV analysis is more helpful for early diagnosis?monitoring and prognostic assessment of some diseases, the method might reflect the balance of autonomic neural system.
