Abstract：Objective To discuss the variation of parameters of heart rate variability in neurally mediated syncope (NMS) in children. Methods Twenty-nine children with NMS (11 males and 18 females, mean age 12.4 ± 2.2 yrs) who came from Peking University First Hospital from April 2007 to March 2008, were included in the study. The hemodynamic patterns of NMS were detected. All patients experienced 24 hours of Hoher monitoring. Parameters of heart rate variability in children with NMS were analyzed. SPSS 10.0 software was used for the statistical analysis of these data. Results There was no significant difference in SDNN between that of NMS group and normal value (P > 0.05). The SDNNi and rMSSD in NMS group increased by 19.21% and 54.07%, respectively (P < 0.05). The pNN50 and triangular index were not significantly different between NMS group and normal value (P > 0.05). Conclusion There is autonomic nerve adjustment imbalance in children with NMS.
