Qualitative beat-to-beat analysis of RR-intervals during steady state air breathing (normoxia) using Poincaré analysis and Frequential analysis. Note the higher dispersion of points in Poincare ellipses in Patients 4 and 5 (responsive to Rebreathing) compared to the others (non-responsive to Rebreathing), indicating higher heart rate variability in these patients
