悸，是指跳动，具体指心下部（胃脘部）的悸动不安。这种情况是由于伤寒病发汗之后，又误用攻下法，导致体内产生虚热而口渴，口渴则饮水过多，水气上凌于心，必然出现畏寒颤抖且心下部悸动的症状。太阳病中，小便不利的患者，若因多饮水，心下部必定会出现悸动；小便量少者，必定会感到腹部拘急不适。脉象浮数，按照常理应当通过发汗来治愈，但如果误用攻下法，会导致身体沉重、心悸，此时不可再发汗，应当等待正气恢复，自然出汗而痊愈。之所以这样，是因为尺部脉象微弱，提示里气虚弱，需要表里之气充实，津液调和，便会自然出汗而病愈。
痉病，表现为身体发热、足部寒冷、颈项强直、恶寒，有时头部发热、面目发热，摇头，突然牙关紧闭，背部挺直、身体向后反张，这就是痉病的症状。这是由于肺部的热邪转移至肾脏，传变而形成的痉病。痉病分为刚痉和柔痉两种：太阳病中，发热无汗反而恶寒的，称为刚痉；发热有汗且恶寒的，称为柔痉。诊察其脉象沉细，这是痉病的脉象特征。
太阳经与少阳经同时发病（并病），脉象浮紧，如果误用攻下法，紧脉反而入里，就会形成痞证。痞证，是指心下部胀满。病发于阴经的，不可使用攻下法，攻下后会导致心下部痞满，按压时感觉柔软无痛，这仅仅是气机阻滞形成的痞证，不可再次攻下。如果热毒之气上乘于心，导致心下部痞满，面色红赤、目黄，胡言乱语、神志恍惚的，这是实证，应当迅速采用催吐或攻下的方法治疗。
结胸证，是指热毒结聚在心胸部。这是由于病发于阳经，过早使用攻下法，热气乘虚而入，导致气机痞结不散。按压时疼痛，脉象寸口部浮，关部反而沉，这就是结胸证的脉象。脉象大者，不可攻下，攻下就会导致死亡。脉象浮大者，攻下是逆治。如果阳脉浮，关上脉小细沉紧，但饮食如常，偶尔小便通利的，称为脏结。脏结病，舌苔白滑，属于难治之症。如果没有往来寒热的症状，病人反而安静，舌上没有苔的，不可攻下。
Ji (Palpitation) refers to movement, specifically the palpitation and trembling felt in the epigastrium (heart below). This condition arises after a Shanghan (Cold Damage) disease has been treated with sweating, followed by erroneous purgation. The resulting internal deficiency-heat causes thirst; excessive drinking of water leads to water qi assaulting the heart, inevitably causing aversion to cold, trembling, and epigastric palpitation. In Taiyang disease (Disease of the Taiyang Channel), if urination is difficult due to excessive water intake, palpitation in the epigastrium will certainly occur. If urine output is scant, the patient will suffer from abdominal urgency. A pulse that is floating and rapid indicates that sweating should normally resolve the condition; however, if purgation is erroneously applied, it results in heaviness of the body and palpitation. At this stage, sweating is contraindicated; recovery occurs through spontaneous sweating. This is because a faint pulse at the Chi position (cun-chi method) indicates interior deficiency. Once the exterior and interior are strengthened and body fluids harmonize, spontaneous sweating will occur, leading to cure.
Jing (Spasm) is characterized by fever in the body but cold feet, stiffness in the neck and nape, aversion to cold, occasional heat in the head, heat in the face and eyes, shaking of the head, sudden locking of the jaw, straightening of the back, and opisthotonos (arching of the back). This is caused by heat transferring from the Lung to the Kidney, transforming into Jing. Jing is categorized into Gang Jing (Rigid Spasm) and Rou Jing (Flexible Spasm). In Taiyang disease, fever without sweat accompanied by aversion to cold is Gang Jing; fever with sweat and aversion to cold is Rou Jing. A deep and fine pulse confirms the diagnosis of Jing.
When Taiyang and Shaoyang diseases occur simultaneously (Bing Bing), and the pulse is floating and tight, erroneous purgation causes the tightness to enter the interior, resulting in Pi Syndrome (Glomus). Pi refers to fullness in the epigastrium. For diseases originating in Yin channels, purgation is contraindicated; applying purgation leads to epigastric pi. Upon palpation, the area feels soft without pain, indicating mere Qi stagnation (Qi Pi); further purgation is forbidden. However, if toxic heat assaults the heart, causing epigastric fullness, red face, yellow eyes, delirious speech, and mental confusion, this indicates an Excess pattern. Rapid emesis or purgation is indicated.
Jie Xiong (Chest Binding) refers to the accumulation of toxic heat in the chest and epigastrium. This results from a Yang-channel disease being treated too early with purgation, allowing heat to invade the deficiency and cause binding obstruction. Tenderness upon pressure, with a floating pulse at the Cun position (inch) and a sunken pulse at the Guan position (middle), characterizes Jie Xiong. A large pulse contraindicates purgation; purging such a pulse leads to death. A floating and large pulse also makes purgation inadvisable. If the Yang pulse is floating, while the Guan pulse is small, fine, deep, and tight, yet appetite remains normal and urination is occasionally clear, this is called Zang Jie (Zang Binding). Zang Jie with a white, slippery coating on the tongue is difficult to treat. In cases without alternating chills and fever, where the patient is calm and the tongue lacks a coating, purgation must not be used.
