Observe The Alteration Of Heart Rate Variability(HRV) In Primary Insomnia(PI) Patients With Different Courses,and Study The Effects Of Acupuncture Applied On PI Patients

Objective To compare the HRV changes in patients with chronic insomnia and short-term insomnia,and to analysis whether the improvement of insomnia is related to the intervention of HRV.Methods Twenty healthy volunteers,twenty short term insomniacs and twenty chronic insomniacs participated in the experiment.Testing HRV of both volunteers and patients before treatment.Recording their time to go to bed and get up,based on the dates the wake and sleep period are defined,then to analysis multiple comparison of healthy volunteers and two groups of patients to find out whether there was any significant change in different periods.The two groups of patients with insomnia using the same therapy,Baihui,Sishencong,Anmian,Shenmeng,Neiguan,Sanyinjiao,Taichong were selected to be acupunctured,and needle warming moxibustion was applied on Qihai,Guanyuan,Five auricular Points(Shenmeng,sympathetic,heart,liver,spleen)are selected to applied with ear points presing.This treatment take twice a week and last for a whole month.24 h HRV of two group of patients are tested on the first and eighth treatment.PSQI scale,WHOQOL-BREF scale should be evaluated before and after treatment.Scale scores and heart rate variability index between and within groups,and correlation analysis,the data were analysised by SPSS19.0 software.Results The general information between the two group of patients and the health group tin age,gender has no significant difference and were comparable.Before treatment,compared with the healthy group,LF,HF,SDANN,and MRSSD in both groups were significantly lower(P<0.05)in the overall(24 hours),sleep duration and awakening period.Compared with chronic insomnia group,the short-term insomnia group has lower(P <0.05)SDANN in awakening period.After the treatment,the scores of the PSQI and WHOQOL-BREF scales in the two insomnia patients were significantly improved(P<0.01);the short-term insomnia group’ total score of PSQI was lower(P<0.05)than the chronic insomnia group.The scores of physiological and psychological domain of the WHOQOL-BREF scale were negatively correlated with the total PSQI scores.After treatment,the HF,RMSSD and PSQI total score change rate of the two groups of insomnia patients was negatively correlated(P <0.05).Conclusion Primary insomnia patients’ sympathetic and parasympathetic tone was lower than healthy people,during wake period patients with short-term insomnia had lower sympathetic tone than those suffered with chronic insomnia.Acupuncture combined with ear acupuncture treatment applied on primary insomnia patients has cumulative effect on the improvement HRV.This therapy shows its effect on curing Primary insomnia by adjusting patients’ parasympathetic tone during sleep.
