针灸对老年高血压患者心率变异性影响

EFFECT OF ACUPUNCTURE ON THE HEART RATE VARIABILITY IN THE ELDER PATIENTS WITH HYPERTENSION

[目的]观察针灸对老年高血压患者心率变异性影响,探索预防减少心率失常发生的可行方法。[方法]采用临床试验,将ASAⅠ～Ⅱ级老年患者40例(43～79岁)随机分成两组:对照组和针灸组。对照组不给予任何处理;针灸组加针刺"内关穴"。记录各组低频(LF)、高频(HF)、低频/高频(LF/HF)。[结果]针灸组LF、HF、LF/HF3项指标均下降,下降幅度分别为41.70%、10.79%、34.96%;LF、LF/HF差异均有统计学意义(P﹤0.05和P﹤0.01);对照组则下降幅度分别为1.72%、2.06%、1.32%,差异无统计学意义。[结论]针灸(内关穴)能够降低交感活性,增高HRV,预防减少心率失常的发生。

[ Objective] To observe the effect of acupuncture on heart rate variability （HRV） in the elder patients with hypertension, and to search for a feasible method for preventing and reducing arrhythmia. [ Methods ] Clinical trial was performed and 40 patients aged 43-79 years with ASA physical status Ⅰ - Ⅱ were randomly divided into two groups： control group and Neiguan acupuncture group. There was no treatment for the control group. The low frequency （LF）, high frequency （HF） and low frequency/high frequency （LF/HF） were recorded. [ Results] Three indexes of LF, HF and LF/HF had descended in the Neiguan acupuncture group, and their amplitudes were 41.70%, 10.79% and 34.96%, respectively. The LF, LF/HF had significant difference （P 〈 0.05 and P 〈 0.01 ）. The their amplitudes of controls were decreased 1.72%, 2.06%and 1.32%, respectively, and the significant different was found among them. [Conclusion] The Neiguan acupuncture can decrease the activation of sympathetic nerve and enhance HRV. It may prevent and reduce arrhythmia.
