摘    要:在HRV频域分析中,比较研究了RR间期作为事件序列与化为时间序列分析所获得的结果。结果表明在平均心率较大和较小的时间片中,频谱将被改变。对后一种分析方法,我们借用“语谱图”的概念,将信号频谱随时间的变化直观地进行显示,提供了HRV时和频域上较完整的变化信息。

关 键 词:心率变异性  频域分析  心率谱图  心电信号分析

Abstract:Frequency analysis approaches of HRV with RR intervals as event series and transferred as time series were compared. The results suggested that the former may introduce some spurious frequency components. Based on the latter procedure, an analysis similar to the spectrogram in speech studies was introduced, a 'Cardio-Spectrogram' obtained in this way could show the variation process of spectra of RR internals with time intutitively, and more information about the time-varying process of the spectrum of HRV could be obtained. The different patterns of 'format' both in low frequency range and high frequency range shown in the cardio-spectrograms for normal subjects and AMI patients may be helpful for clinical diagnosis and for exploration of the sympathetic vs. vagus control balance of heart rate for these different subjects.
Keywords:HRV  frequency analysis  cardio-spectrograms
