Table 4 Supplemental power spectral data, i.e. cumulative intensity of high-frequency band of systolic blood pressure (HF-SBP) and of low-frequency band of heart rate (LF-HRV), is shown in normal control animals following sham surgery and in hypertensive animals (2-kidney-1-clip (2K1C)) with and without irbesartan (Irb) treatment
