心下筑筑惕惕，怔怔忡忡，悸病之状也。饮水多而小便少，水停心下，宜茯苓甘草汤，或五苓散。厥冷
为寒，宜真武汤。汗后为虚，宜小建中汤。或不因汗后，是虚之甚也，宜炙甘草汤。
战谓身抖耸动也，栗谓心内发HT 也，振亦耸动，比之于战则无力也。所以论中曰振振者，皆
责其虚也。栗邪气为之也，战正气为之也，邪正相交故争也。此证若生于汗吐下之后，是虚其中外而致逆
也，若不致逆邪，因以衰正，因以和而作解，则为正胜邪却，战栗汗出而平也。

心下（胃脘部）悸动不安，心慌恐惧，这是心悸病的症状表现。如果饮水多而小便少，说明水饮停聚在心下，适宜使用茯苓甘草汤，或者五苓散。四肢厥冷属于寒证，适宜使用真武汤。发汗后出现此症属于虚证，适宜使用小建中汤。如果不因发汗后出现，则是虚损非常严重，适宜使用炙甘草汤。
“战”是指身体颤抖耸动，“栗”是指内心感到恐惧震动，“振”也是耸动，但比起“战”来力量较弱。所以《伤寒论》中说凡是提到“振振”的，都归咎于正气虚弱。“栗”是由邪气引起的，“战”是由正气引起的，邪气与正气相互交争，所以产生争斗之象。这种病症如果发生在发汗、催吐或泻下之后，是因为中焦及体表正气亏虚导致气机逆乱；如果不能通过逆乱来驱除邪气，反而因为正气衰弱，通过调和使病情缓解，那么就是正气战胜邪气，通过战栗出汗而痊愈。
现在称为呃逆，在古代称为哕（yuě）。哕是指气机噎结而有声音。世间有人将哕等同于呃逆，大概是不了解哕的声音，其声是从胃里经过肛门排出的，不像呃逆那样格格连声。呃逆之气从脐下冲脉而来，经过肛门发出声音。呃逆颇类似嗳气和噫气：嗳气是因为进食太急，此时打嗝转出食气；噫气是因为过食、伤食或暴饮暴食，打出带有食物腐臭气味的气体。这些都属于气机上逆导致的疾病。呃逆的病机在于胃气虚竭。兼有热证的，以橘皮竹茹汤加柿蒂为主方治疗。兼有大便不通利的，以三承气汤为主方治疗。兼有小便不通利的，以五苓散汤为主方治疗。兼有肾虚不能摄纳冲脉之气回归本原的，以都气汤加牛膝为主方治疗。兼有寒虚证的，如果在太阴经表现为手足温暖，以吴茱萸汤或理中汤为主方治疗；如果在少阴经表现为手足厥冷，则再加附子。兼有痞满硬痛且下利的，以生姜泻心汤为主方治疗。兼有痞满硬痛且噫气的，以旋复代赭石汤为主方治疗。
The sensation of palpitation and fearfulness in the epigastrium (region below the heart) characterizes the disease of Heart Palpitations (Xin Ji). If there is excessive water intake but scanty urination, it indicates Water Retention in the Epigastrium; Fuling Gancao Tang (Poria and Licorice Decoction) or Wuling San (Five-Ingredient Powder with Poria) are appropriate. Limb coldness indicates Cold syndrome; Zhenwu Tang (True Warrior Decoction) is appropriate. Occurrence after sweating indicates Deficiency; Xiaojianzhong Tang (Minor Construct the Middle Decoction) is appropriate. If it occurs not after sweating, it signifies severe Deficiency; Zhigancao Tang (Honey-Baked Licorice Decoction) is appropriate.
"Zhan" refers to bodily trembling and shivering; "Li" refers to inner mental fear and trembling; "Zhen" also denotes shivering, but is weaker than "Zhan". Therefore, the Treatise states that instances of "Zhenzhen" are all attributed to Deficiency. "Li" is caused by pathogenic factors; "Zhan" is caused by healthy Qi. The contention arises from the interaction between pathogenic factors and healthy Qi. If this syndrome occurs after sweating, vomiting, or purging, it results from Deficiency in the interior and exterior leading to rebellious Qi. If the rebellion does not expel the pathogen, but rather the healthy Qi declines, and harmony is restored allowing resolution, then healthy Qi overcomes the pathogen, and the patient recovers through shivering and sweating.
What is now named E'ni (Hiccups) was formerly named Yue (belching with sound). Yue refers to Qi obstruction with audible sounds. Some people equate Yue with E'ni today, likely due to ignorance: the sound of Yue emanates from the stomach and exits through the anus, unlike E'ni which produces a continuous "ge-ge" sound. The Qi of E'ni originates from the Chong Mai (Penetrating Vessel) below the navel and makes sound upon exiting through the anus. E'ni resembles Aqi (belching) and Yi qi (eructation): Aqi occurs due to eating too quickly, releasing food Qi; Yi qi occurs due to overeating, damaged food, or binge eating, releasing foul-smelling food Qi. All belong to diseases of Rebellious Qi. The pathology of E'ni lies in the exhaustion of Stomach Qi. For cases accompanied by Heat, Jupi Zhuru Tang (Tangerine Peel and Bamboo Shavings Decoction) added with Persimmon Calyx (Shidi) is the primary formula. For cases accompanied by constipation, the Three Chengqi Tangs (Three Draining Qi Decoctions) are used. For cases accompanied by dysuria, Wuling San Tang (Five-Ingredient Powder with Poria Decoction) is used. For cases accompanied by Kidney Deficiency failing to control the Qi of the Chong Mai returning to its origin, Duqi Tang added with Achyranthes Root (Niuxi) is used. For cases accompanied by Cold and Deficiency, if presenting in the Taiyin stage with warm hands and feet, Wu Zhu Yu Tang or Lizhong Tang (Regulate the Middle Decoction) is used; if presenting in the Shaoyin stage with cold limbs, Aconite (Fuzi) is added. For cases accompanied by fullness, hardness, and diarrhea, Shengjiang Xiexin Tang (Fresh Ginger Bitter Decoction) is used. For cases accompanied by fullness, hardness, and eructation, Xuanfu Daizhe Shi Tang (Inula and Hematite Decoction) is used.
