1、要目的：观察针刺灵台、神道穴对原发性高血压（EH)患者心率变异性（HRV)5rain频域指标LF(低频）、HF(高频）、LF/HF(低频/高频）的影响，并与针刺双侧悬钟穴对照，以期证实灵台、神道穴对HRV的相对特异性影响，从而为临床上针刺治疗高血压及其相关的心脏并发症优选腧穴提供客观依据。方法：研究中共纳入38例患者，随机分为观察组23例和对照组15例。观察组针刺灵台、神道穴，观察针刺前后HRV5min频域指标LF、HF、LF/HF的变化，对照组针刺双侧悬钟穴，观察针刺前后上述指标的变化。对所得数据进行统计学分析，观察两组是否存在统计学差异。结果：组内比较：观察组HRV5min频域指标L

2、F在针刺后明显降低，针刺前后比较有显著性差异(P〈0.05)；HF在针刺后有所提高，但针刺前后比较无统计学意义；LF/HF针刺前后比较有显著性差异(P〈0.05);对照组HRV5min频域指标在针刺后有变化，但无统计学意义。组间比较：观察组和对照组的LF、HF、LF/HF在针刺前比较无统计学意义，针刺后观察组LF、LF/HF较对照组改善明显(P<0.05)，HF的比较无统计学意义。’结论：针刺灵台、神道穴能降低原发性高血压（EH)患者HRV5min频域指标中的LF及LF/HF，提示针刺这两个穴位可能具有降低交感神经活性、调整自主神经均衡性的作用。关键词针刺效应；穴，灵台；穴，神道；原发性
