人迎寸口脈法在《黃帝內經》中是非常重要的診斷方式，並廣泛的運用於診斷疾病與指導針灸治療的取穴、補瀉等。然而，對於人迎寸口脈的實質所指為何，從古至今一直存在相當多的爭論。本文透過整理與分析《黃帝內經》中提及人迎、寸口、脈口、氣口之條文，並蒐集各家論述與期刊文章，來探討人迎寸口脈究竟所指為何，以及在歷史的演變進展中有何變化。經研究分析後，本文認為《黃帝內經》中的人迎寸口脈即是頸動脈與橈動脈，而其大小之別當指脈之動勢而非解剖構造；除此之外，可以發現《黃帝內經》一書中存在著診脈法歷史演進的脈絡，依序從十二經遍診法、三部九候法、人迎寸口脈法，到最後發展出獨取寸口脈法之理論與臨床運用的基礎。希望本文能對同道在人迎寸口脈法相關之典籍閱讀與臨床運用上，有所助益。

Pulse diagnosis method by comparing Renying(人迎) and Cunkou(寸口) is a very important clinical skill in “Huangdi Neijing”(黃帝內經). It is a guidance to choose the acupoint and manipulation (supplementation and drainage) in acupuncture therapy. However, there is still many different ideas about the real anatomy position about Renying and Cunkou. In this article, all chapters in “Huangdi Neijing” which mention about Renying, Cunkou, Maikou(脈口) and Chikou(氣口) was collected. We use the information from these articles and published journal to infer the original meaning and observe the historical development process of pulse diagnosis method. The result showed that pulse diagnosis method by comparing Renying and Cunkou pulse in “Huangdi Neijing” means the comparison between carotid and radial pulse tendency. The historical development process of pulse diagnosis method can be observed in “Huangdi Neijing” from “twelve regular channels pulse-takings”(十二經遍診法), “three portions and nine pulse-takings” (三部九候), “Renying and Cunkou pulse-takings” to “Cunkou only pulse-takings”. Explorate the Renying and Cunkou’s position may help the clinical use of pulse diagnosis from Huangdi Neijing.
