Search for: [Abstract = "other hand, Group 1 and 2 demonstrated a significant decrease of pNN50 as compared to healthy subjects of Group 3 \(Group 1 \- 22.7 vs. 24.5 %, p<0.003and Group 2 \- 22.1 vs. 24.5 %, p<0.002 \), depressed HF values \(Group 1 \- 3040.8 vs. 3373.1 ms2, p<0.003 and Group 2 \- 2764.5 vs. 3373.1 ms2, p<0.002\) and an increased LF\/HF ratio \(Group 1 \- 1.7 vs. 1.3 and Group 2 \- 2.1 vs. 1.3\). The author also compared the mean values of HRV parameters in children with NS and TT\(\+\), with NS and TT\(\-\) and in Group 3 children. The values of pNN50 showed no significant differences in children with NS and TT\(\-\) as compared to normal children \(23.0 vs. 24.5%, p=0.13\), but they were significantly different in children with NS and TT\(\+\) and in healthy children \(22.5 vs. 24.5%, p<0.003\). Although regardless of the TT result, the value of HF in children with NS was lower than the corresponding value in normal children, yet it did not reach the level of statistical significance. The LF\/HF ratio in children with NS was statistically higher in children with NS as compared to normal Group 3 children \[TT\(\-\) 1.47 vs.1.3, p<0.003 and TT\(\+\) 1.39 vs.1.3, p<0.05\]. A similar comparison was carried out between HRV parameters in Group 2 children taking into consideration their TT results and the corresponding values in Group 3 subjects. With the exception of pNN50, also RMSSD was significantly lower in children with"]
