Effect of chronic normobaric hypoxia on time-domain analysis of heart rate variability. a Relationship between the duration of a cardiac cycle (RR interval, n; (R–R)n) and that of the next one (RR interval, n + 1; (R–R)n+1) and in a control rabbit. b Relationship between the duration of nth RR interval, (R–R)n, and the following RR interval, (R–R)n+1, in a CNH rabbit. c Mean SD1 was similar in control and CNH rabbits, while mean SD2 was significantly lower in CNH than in control rabbits. Empty bars: control rabbits (n = 11). Filled bars: CNH rabbits (n = 8). *p < 0.05. Dispersion bars: SEM
