Clinical characteristics, upright haemodynamic measurements, and heart rate variability indices among the 42 patients with head up tilt test (HUT) induced symptoms

  • Values are mean (SD).

  • 5-150 (Univariate analysis): p < 0.05 (5 min vend HUT results between groups).

  • BA, bandwidth area; BP, blood pressure; HF, high frequency (0.15 to 0.4 Hz); HR, heart rate; LF, low frequency (0.04 to 0.15 Hz); PP, power peak.
