Based on ZHANG Zhongjing’s exposition of "weak pulse at yang and wiry pulse at yin" for chest discomfort and heart pain

this paper summed up the experience of ZHAO Qingchun in applying Wentong Decoction（温通汤） to treat chest discomfort and heart pain. Meridian obstruction

unsmooth blood circulation

phlegm turbidity

blood stasis

cold coagulation

and qi stagnation in the chest are the key to the pathogenesis of chest discomfort and heart pain. According to the basic pathogenesis of "weak pulse at yang and wiry pulse at yin"
