Chinese/Japanese Pulse Image chart: Knotted Pulse (jiemai)

Illustration of Knotted Pulse (jiemai) from Renyuan maiying guizhi tushuo (Pictorial Handbook of Pulse Images Based on the Person). This is a specialist text on pulse diagnosis attributed to the third-century master Shuhe, edited and revised by Shen Jifen in the Ming period (1368-1644). It discusses various pulse images and the medical conditions to which they relate, and contains 48 pulse image diagrams. This undated edition was engraved and published in Japan.

The text states: Knotted Pulse refers to a pulse with a relatively slow rate, exhibiting irregular pauses; i.e. the pulse image is characterised by a slow pulse rate with an irregular rhythm. Knotted Pulse relates to disorders of preponderant Yin (yin sheng) and stagnant Qi (qijie).
