论述说：胸痹短气，是由于脏腑虚弱，阴阳失调，风冷邪气侵袭并注于胸中。脉象表现若太过或不及，出现“阳微阴弦”的脉象，就会导致胸痹且疼痛。之所以如此，是因为极度虚损的缘故。“阳微”主病在胸痹，“阴弦”主病在腹痛。另外，肺主司呼吸之气，肺气虚弱则人会出现短气。普通人若无寒热症状，但感觉短气、气息不足以接续，这是体质实盛的表现。实证则气机旺盛，气盛则气机上逆，气逆则运行不通畅，因此也会发生短气。凡是脉象表现为沉、迟、小、紧的，都是胸痹短气的征候。

It is stated that chest bi (Chest Obstruction) and shortness of breath are caused by the weakness of the zang-fu organs, disharmony of yin and yang, and the invasion and accumulation of wind-cold pathogenic factors in the chest. If the pulse is excessive or deficient, presenting a "superficially weak and deep-taut" (Yang Wei, Yin Xian) pattern, it leads to chest bi accompanied by pain. This occurs due to extreme deficiency. A superficially weak pulse indicates chest bi, while a deep-taut pulse indicates abdominal pain. Furthermore, the Lung governs Qi; when Lung Qi is deficient, one experiences shortness of breath. In an ordinary person without chills or fever, if there is shortness of breath with insufficient respiratory capacity, it indicates a constitution of excess. Excess implies abundant Qi; abundance leads to rebellious Qi flow; rebellion causes obstruction; thus, shortness of breath also results. Any pulse appearing deep, slow, small, or tight is indicative of chest bi and shortness of breath.
