Her right pupil was 1.5 mm and had an oval shape, with no response to light (Figure 1); the left pupil measured about 6 mm and responded very poorly to light.
HRV in the supine position. (a) The total Fourier spectrum, (b) the histogram, (c) the tachogram, and (d) the Poincare plot. The sympathovagal balance (SVB = LF/HF) was 1.31 versus 0.85 +- 0.3 in controls. The total power of LF was 6.4 versus 8.1 +- 2.5 in controls, and the total power of HF 4.9 versus 10.1 +- 3.6 in controls. The tachogram, the histogram, and the Poincare plot show a loss of variability across all frequencies.

The HRV was ostensibly decreased in the time domain in the supine and standing position and also during rhythmic breathing (Figures 2, 3, and 4).
HRV in the standing position. (a) The total Fourier spectrum, (b) the histogram, (c) the tachogram, and (d) and the Poincare plot. In (a), the sympathovagal balance is included (SVB = 1.62 versus 1.5 +- 0.6 in controls). The normal SVB seems to be due to a severe reduction of the total power of HF and a less severe reduction of LF so the ratio remained normal. The total power of LF was 5.0 versus 6.2 +- 1.9 in controls, and the total power of HF was 3.10 versus 10.1 +- 3.6 in controls. There was a severe loss of variability across all frequencies.

HRV during rhythmic breathing. (a) The total Fourier spectrum, (b) the histogram, (c) the tachogram, and (d) the Poincare plot. In (a), the sympathovagal balance is included (SVB = 3.27 versus 1.83 +- 0.5 in controls); the total power of LF was 2.8 versus 4.3 +- 2.4 in controls, and the total power of HF was 0.9 versus 2.4 +- 1.2 in controls. Although some respiratory driving is present, the magnitude of the driving is abnormally decreased.
