Power spectrum analysis of cardiovascular variability in anaesthetised SHR and WKY rats

Power spectrum analysis of cardiovascular variability in anaesthetised SHR and WKY rats

A comparative analysis of beat-to-beat heart rate variability (HRV) and arterial blood pressure variability (BPV) was performed in a group of four spontaneous hypertensive rats (SHR) vs. A control group of four Wistar-Kyoto (WKY) rats. All them were anaesthetised with sodium pentobarbital. HRV and B...

Zusammenfassung:A comparative analysis of beat-to-beat heart rate variability (HRV) and arterial blood pressure variability (BPV) was performed in a group of four spontaneous hypertensive rats (SHR) vs. A control group of four Wistar-Kyoto (WKY) rats. All them were anaesthetised with sodium pentobarbital. HRV and BPV power spectra were computed by a parametric method based on autoregressive models (AR). The authors' HRV spectral analysis showed a high frequency (HF) component whose amplitude was lower (46%, p
