The Effects Of Heart Rate Variability(HRV)by Acupuncturing Taichong Acupoint(LR3)of Patients With Cerebral Infarction

Objective:To observe the change of each index of HRV by acupuncturing the left Taichong acupoint,explore the effects of acupuncturing Taichong acupoint on the autonomic nervous function of convalescent cerebral infarction patients,and providing the effective evidence for clinical whether or not the treatment of cerebral infarction patients with an imbalance by acupuncturing Taichong acupoint.Method:All 30 convalescent cerebral infarction patients meet the inclusion criteria were selected randomly from the wards of The First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine,including 18 cases of male patients,12 cases of female patients.The mean age is 58.3±7.85 years old,the mean disease course is 47.07±14.81 days.Acupuncturing the left Taichong acupoint of the subjects.Detecting the HRV index with dynamic electrocardiogram-medilog AR12 and recording the indicators,such as SDNN、RMSSD、PNN50、ULF、ULF%、LF、HF、LF%、HF%and LF/HF at the 0th(5 minutes before acupuncturing),5 th(acupuncturing),10th(5 minutes after acupuncturing),15th(twirling the needle),20th(5 minutes after twirling the needle),25th(withdrawing the needle),30th(5 minutes after withdrawing the needle)minute.By using the repeated measures data of ANOVA to make a statistical analysis with the indicators.Results:1.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,Mean BPM decreased significantly at the time of twirling the needle(p<0.01)and the moment of withdrawing the needle(p<0.05).2.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,LF decreased significantly at all the moment(p<0.01).3.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,HF decreased significantly at all the moment(p<0.01).4.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,LF%decreased significantly all the time(p<0.01)except the moment of withdrawing the needle(p<0.05).5.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,HF%decreased significantly all the time(p<0.01).6.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,LF/HF decreased significantly at the moment of 5 minutes after acupuncturing,the moment of withdrawing the needle,5 minutes after withdrawing the needle(p<0.01),also increased significantly at the moment of acupuncturing(p<0.05).7.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,ULF increased significantly at the time of twirling the needle(p<0.01),also at the moment of acupuncturing and 5 minutes after withdrawing the needle(p<0.05)8.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,ULF%increased significantly all the moment(p<0.01).9.Compared with the moment of 5 minutes before acupuncturing the left Taichong acupoint,SDNN、RMSSD、PNN50 changed non-significantly(p>0.05).Conclusion:1.Acupuncturing Taichong acupoint could make the sympathetic nerve tension of cerebral infarction patients decreased significantly.2.Acupuncturing Taichong acupoint could make the parasympathetic nerve tension of cerebral infarction patients decreased significantly.3.Acupuncturing Taichong acupoint could adjust the balance of autonomic nervous system,and chiefly changes to the parasympathetic nerve’s superior side.
