PC6 is a classic acupuncture point in traditional Chinese medicine. It is considered to be effective when treating cardiovascular disorders. In the present review the authors have focused on the neurophysiological bases of the effects of PC6 stimulation on cardiovascular mechanisms. Experimental studies have shown that the hypothalamic rostral ventrolateral medulla, arcuate nucleus and ventrolateral periaqueductal gray are involved in acupuncture attenuation of sympathoexcitatory cardiovascular reflex responses. This long-loop pathway also appears to contribute to the long-lasting, acupuncture-mediated attenuation of sympathetic premotor outflow and excitatory cardiovascular reflex responses. Acupuncture of PC6 modulates the activity in the cardiovascular system, an effect that may be attributed to attenuation of sympathoexcitatory cardiovascular reflex responses.
PC6 是中医的经典穴位，在治疗心血管疾病方面被认为是有效的。在本综述中，作者重点关注了 PC6 刺激对心血管机制影响的神经生理学基础。实验研究表明，下丘脑吻侧腹外侧髓质、弓状核和腹外侧导水管周围灰质参与了针刺抑制交感兴奋性心血管反射反应。这条长环通路似乎也有助于长期的、针刺介导的抑制交感节前传出和兴奋性心血管反射反应。针刺 PC6 调节心血管系统的活动，这种作用可能归因于抑制交感兴奋性心血管反射反应。
