- 1. MHRT came to be significant in the Sa~am Acupuncture Group(心正格).
- 4. TP wasnot statistically significant in both the Sa-am Acupuncture Group(心正格) and the control group.
- 6. LF/HF ratio came to be significant in the control group.
제안 방법
- Korea), the sphygmograph for the HRV. In this study, we calculated Mean Heart Rate(MHRT), Standard Deviation of all the Normal RR intervals(SDNN), and Root Mean Square of Successive Differences Between The Normal Heart Beats(RMSSD) as well as Total Power(TP), LF(Low Frequency), and High Frequency (HF) after measuring the HRV for 5 minutes. Using these data, we figured out normalized low frequency power(LF norm), nonnalized high frequency power(HF norm), and LF/HF ratio, we analyzed the equilibrium of the sympathetic and parasympathetic nerves, and the activities of the autonomic nerves that have to do with heart, the changes of the heart rates due to stress from the outside of the body, the mean heart rates acquired from the recording time of the MHRT, SDNN, RMSSD, TP, LF, HF, and LF/HF ratio gained by the HRV of the Sa~am Acupuncture Group(心正 格)and the control group.
- This study was performed for two months, from May first, 2006 to June thrity first, 2006.
- In this study, we calculated Mean Heart Rate(MHRT), Standard Deviation of all the Normal RR intervals(SDNN), and Root Mean Square of Successive Differences Between The Normal Heart Beats(RMSSD) as well as Total Power(TP), LF(Low Frequency), and High Frequency (HF) after measuring the HRV for 5 minutes. Using these data, we figured out normalized low frequency power(LF norm), nonnalized high frequency power(HF norm), and LF/HF ratio, we analyzed the equilibrium of the sympathetic and parasympathetic nerves, and the activities of the autonomic nerves that have to do with heart, the changes of the heart rates due to stress from the outside of the body, the mean heart rates acquired from the recording time of the MHRT, SDNN, RMSSD, TP, LF, HF, and LF/HF ratio gained by the HRV of the Sa~am Acupuncture Group(心正 格)and the control group.
대상 데이터
- in his forties. 29 people were men, and 8 people were women in this group.
- The vital signs that come from the HRV test largely divides into data of time and data of frequencies. The Data of time is MHRT, MeanNN(mean of all the normal RR intervals), SDNN, and RMSSD. The data of frequencies if TP, VLF(veiy low frequency), LF, HF, and LF/HF ratio.
데이터처리
- To compare MHRT, SDNN, RMSSD, TP, LF, HF, and LF/HF ratio of the Sa~am Acupuncture Group(心正格)with those of the control group, we did paired T-test, and used SPSS 12.0 for the statistics, and examined these data in the significance level of 5%.
성능/효과
- 2. SDNN wasnot statistically significant in both the Sa-am Acupuncture Group(心正格)and the control group.
- 3. RMSSD wasnot statistically significant in both the Sa-am Acupuncture Group(心正格) and the control group.
- 93, but it wasnot statistically significante二09L). Comparing LF and HF which is the low frequency range and high frequency range for the recording time between the groups, LF of the control group decreased from 393.02+527.06 to 305.45+306.67, and HF of the control group increased fnm 261.88±253.5 to 328.00±476.25, but it wasnot statistically significant (p二0.34, 0.36). LF of the treatment decreased from 1202.
- 5 to 2 are normal ranges of LF/HF ratio which is widely used as the indexes of ability of regulating the autonomic nerve system between the groups, and this is in proportion to the activities of the sympathetic nerve, and is in inverse proportion to the activities of the parasympathetic nerve. In this study, LF/HF ratio of the control group decreased from 1.74士L46 to L55±1.39, but it wasnot statistically significant(p=0.22), and LF/HF ratio of the Sa-am Acupuncture Group(心正格)decreased from 3.36± 4.51 to 1.98±1.及 and it was statistically significant (p=0.02). As to the results, we speculate that Sim-Jung-Gyuk(心正格)lessens exasperation of the autonomic nerve system.
- Bradycardia that makes MHRT go down is usually shown when we have an acute heart attack, too many drugs, hypothyroidism. In this study, MHRT of the control group decreased from 73.70±11.39 to 花86±10.82, but it wasnot siginificant statistically(p=0.57). MHRT of the Sa-am Acupuncture Group(心正格)decreased from 69.
- It implies that the risk of having cardiac diseases would be higher when RMSSD which is the square root of the mean value a square of discrepancies of contiguous RR intervals goes under 10. In this study, RMSSD of the control group increased from 29.49+15.73 to 31.25±18.48, but it wasnot statistically significant(p=0.52), and RMSSD of the Sa-am Acupuncture Group(心正格) increased from 44.12+24.27 to 44.34+23.81, but it wasnot statistically significant(p=0.92). The values of TP that means total power including VLF, LF, and HF of the recording time between the Sa-am Acupuncture Group(心正格)and the control group is said to be in normal range when it is over 1000, and it implies that the decrease of TP shows the lesser ability of regulating the body due to the chronic diseases or stress, In this study, TP of the control group increased from 1151.
- In this study, the normal ranges of the values of MHRT which, means the mean heart rate for the recording time of the Sa-am Acupuncture Group(心正格)and the control group are said to be from 60 to 90. Tachycardia that makes MHRT go up is usually shown when we are in stress, anxiety, hyperthyroidism, and take the stimulants.
- MHRT of the control group decreased from 73.70±11.39 to 72.86±10.82, but it wasnot statistically significant (p=57), MHRT of the Sa-am Acupuncture Group(心正格)decreased from 69.46±9.69 to 66.87±7.90, and it was significant(p=z0.00)(Fig. 1).
후속연구
- But the same method was kept on in this study. Therefore, we consider that additional experiments on how Sa-am AcupuncHire(心正格)does affect the autonomic nerve system would be needed after this study.
