Abstract Objective To explore the change of deceleration capacity of rate(DC) in patients with traumatic fracture and the correlation between DC and heart rate variability （HRV）.Methods 60 cases of patients with traumatic fracture were divided into two groups according to their ages: Group I(age 40-60) and Group Ⅱ(age 61-80). Both of groups were detected by dynamic electrocardiogram for 24 hours and calculated the DC and HRV indexes.Results DC of Group I was (6.08±1.74) ms；DC of Group Ⅱ was (5.13±0.82) ms；DC was positively correlated with HRV indexes such as SDNN, rMSSD, pNN50 and HF(P<0.01), and was negatively correlated with HR. Conclusion There was a good correlation between indexes of DC and HRV in patients with traumatic fracture. DC can independently be an index of the autonomic nerve function tests.
