沉脉的特征、形成机制及主病研究

Study on characteristics,mechanism,and diagnostic significance of deep pulse

从脉象特征、影响因素、形成机制、浮沉比较、所主病证5个方面对沉脉进行了阐述。其特征是脉位较低,轻取不应,重按乃得;影响因素包括体型、季节、性别;沉脉的形成与疾病的表里、气血的强弱、气机郁滞的程度、邪气的性质及多少有密切关系;借助浮沉脉象的比较,可判断正气的强弱,邪气的多少以及病位和病势;沉脉主里此为常规,多见于阴寒内盛、水饮、阳气虚衰、气机郁滞、血虚、阴虚内热等情况;沉脉也有主表之时,多见于表证初期和太少两感。

This paper elaborates on deep pulse from the following aspects ： the characteristics of pulse manifes- tation, influential factors, the mechanism of deep pulse formation, comparison between floating pulse and deep pulse, and the diseases that deep pulse indicates. Deep pulse has a relatively low pulse position, which cannot be felt when lightly touched and can only be felt when heavily touched. The influential factors for deep pulse include body type,season, and sex. The formation of deep pulse is closely related to the superficies and interior of diseases, strength of qi - blood, the degree of depression and stagnation of qi movement, and the nature and amount of patho- genic qi. The strength of vital qi, amount of pathogenic qi, and disease location and tendency can be judged by com- paring the pulse manifestations of floating pulse and deep pulse. Deep pulse usually indicates interior syndromes and is mostly seen in internal exuberance of yin - cold, water - rheum, deficiency of yang qi, depression and stagnation of qi movement, blood deficiency, and yin deficiency with internal heat. Deep pulse also indicates superficies syndromes and is mostly seen in the early stage of superficies syndrome and a combination of Taiyang and Shaoyang syndromes.
