摘要

This study we used the ECG, blood-pressure-pulse recorder to analyze the heart rate variability, the blood pressure variability of 12 healthy males (20~30 years old) and 10 hypertensive patients (30~50 years old) after the subjects were stimulated by 2Hz Low Frequency Electrical Stimulation (LFES) for 10 minutes. In the healthy males, from the FFT spectrum analysis of ECG and pulse pressure graph, we found that the LFES applied on auricular Jiang Ya Gou could induce a significant decrease in the high frequency (0.04~0.15Hz) component of HRV and PRV, as well as a significant increase in the low frequency (0.001~0.04Hz) part (p＜0.05). These results indicated that the sympathetic nerve was activated after stimulation, and the parasympathetic nerve was in restrained condition. In the time domain analysis, it showed that both the heart rate and pulse rate increased after stimulation in the experimental group (p＜0.05). Moreover, the results showed that after the LFES on both side of Jiang Ya Gou could reduce systolic blood pressure but no conspicuous variation in diastolic pressure. We also found the hypertensive patients were contrary to healthy males' situation. Discussion with the experimental results, we conjectured boldly that LFES on auricular Jiang Ya Gou could affect immediately the variation of blood pressure because of complex blood adjustable system and further change of the heart rate.
