结脉者,迟缓而时一止,为阴也,主阴盛发躁烦满,或阳厥极深,以至身
冷,脉微欲绝,而缓弱时一止者,亦胸烦躁,此止为热极而非寒也,皆须以标本明之。
促脉者,阳也,数而时一止也,主聚积、气痞,忧思所成;亦或热剧失下,则令脉促。下之则平也。
代脉者,主缓弱而无力不能动,因而复动,病必危而死。
趺阳脉者,胃土之脉也。趺阳脉迟而缓者,胃气如经也。
动在足趺阳之经,故曰趺阳。一曰冲阳者,阳明所过之原。过者,冲也。
如经,如本经之常脉。
滑为胃实,紧为脾强。浮而滑者,浮为胃虚,滑则为哕。浮而鼻中燥者,必衄
也。沉为胃实(上本下故也),数为消谷(胃热故也),紧则难治。盖四时五脏皆以胃气为本,
紧燥盛而土湿气衰,故曰难治。浮而大者,气实血虚也(气为阳、血为阴故也)。浮而涩者,
胃虚下利也(去液故涩)。伏而涩者,伏则吐逆,水谷不化(内湿故也),涩则气不下食,脉不出则身冷肤硬。
太溪者,肾水之脉也,动于左足内踝下后、跟骨下陷中,足少阴肾水之胃,故
曰大浮也。太溪脉,则肾气如经也,弱则微烦,涩则厥逆(微厥也)。
阳病热证不退,反见阴脉者死(脉近于绝故也);汗后热退而见阴脉者愈。阴阳证
脉平愈。伤寒咳逆上气,脉散者死(形损故也);脉浮而洪,身汗如油,喘而不休,水
浆不入,形体不仁(不仁者不和也),乍静乍动,命绝也;汗出发润,喘不休者,肺先绝
也;阳反独留,体如烟薰,直视摇头,心先绝也。唇吻(音稳)反青,四肢 习者,
肝绝也( ,丑入切,汗出也。习,水流不绝,此言汗不止也)。环口黧黑,柔汗发黄者,脾先
绝也(柔,虚也)。溲便遗失,狂言直视者,肾先绝也(溲,小便。便,大便)。寸口脉阴阳俱紧
盛(寸口即气口,此言三部,关前为阳,关后为阴),大汗出,不解者死;身热喘粗,见阳脉而
躁者死(汗不胜病也)。汗后微热不解者,病不可便言死也,脉如转索者当日死,谵语、
身微热、脉浮大,手足温者生,欲作大汗故也(俗作好汗);脉暴出者死,阴衰欲绝,
而阳暴独胜则脉暴出,少间阴气先绝,则阳气后竭而死矣;逆冷,脉沉细者,不
过一日死(死证多矣,以致危极则无越此矣)。
结脉,脉来迟缓且偶尔出现一次停顿,属于阴脉,主要主病为阴气过盛导致烦躁、胸闷胀满;或者是阳气郁厥极深,以至于身体冰冷,脉搏微弱几乎摸不到,且缓慢虚弱中偶尔出现一次停顿的,也是胸中烦躁,这种停顿是由于热邪极盛而非寒邪所致,都需要通过辨别标本(病因与症状的主次关系)来明确诊断。
促脉,属于阳脉,脉来急促且偶尔出现一次停顿,主要主病为体内有积聚、气机痞塞,多由忧思过度引起;或者是因为热邪剧烈而未能及时攻下,从而导致脉象急促,经过攻下治疗后脉象即可平复。
代脉,主要表现是脉来缓弱无力,不能连续跳动,需要停顿片刻才能再次搏动,出现这种情况,病情必定危重,预后不良,可能导致死亡。
趺阳脉,是反映胃土功能的脉象。趺阳脉如果迟而缓和,说明胃气符合常经(正常状态)。
因为该脉动位于足背部的阳明经上,所以称为趺阳脉。另一种说法认为冲阳穴是阳明经经过的原穴。“过”的意思就是“冲”。
所谓“如经”,是指如同本经正常的脉象。
脉滑表示胃中有实邪,脉紧表示脾脏功能强盛。脉浮而滑,其中浮象表示胃气虚弱,滑象则预示会出现呃逆(哕)。如果脉浮且鼻中干燥,一定会发生鼻出血(衄血)。
脉沉表示胃中有实邪(因为上部本虚而下部实),脉数表示消谷善饥(因为胃中有热),脉紧则表示难以治疗。大概四季五脏都以胃气为本底,如果脉象紧燥且邪气盛而脾胃湿气衰败,所以说难以治疗。脉浮而大,表示气实血虚(因为气属阳、血属阴)。脉浮而涩,表示胃虚并伴有腹泻(因为津液流失所以脉涩)。脉伏而涩,脉伏表示呕吐逆乱,水谷不消化(因为内有湿邪),脉涩表示气机不畅无法进食,如果脉搏摸不到则身体冰冷、皮肤僵硬。
太溪脉,是反映肾水功能的脉象,搏动位于左脚内踝后方、跟骨下方的凹陷处,这里是足少阴肾经的“胃气”所在之处,所以脉象往往表现为大且浮。太溪脉如果柔和,说明肾气符合常经;脉弱则会有轻微烦躁,脉涩则会出现四肢厥冷(轻微的厥逆)。
阳病热证如果不退,反而出现阴脉的,预后不良,会导致死亡(因为脉象接近断绝);出汗后热退却出现阴脉的,则会痊愈。阴阳证候与脉象平和则疾病向愈。伤寒咳嗽气逆上冲,脉象散乱的,预后不良,会导致死亡(因为形体受损);脉象浮而洪大,身体出汗如油,喘息不止,无法进水进食,形体麻木不仁(不仁即气血不和),时而安静时而躁动,这是生命终结的表现;出汗后头发湿润,喘息不止的,是肺先衰竭;阳气反常独留于外,身体颜色如烟熏般黑黄,两眼直视且摇头,是心先衰竭。嘴唇和口角发青,四肢抽搐颤动的,是肝先衰竭(“ ”音同“丑入切”,意为汗出;“习”指水流不绝,这里形容汗出不止)。口周发黑,出冷汗且汗色发黄的,是脾先衰竭(“柔”意为虚弱)。大小便失禁,胡言乱语且两眼直视的,是肾先衰竭(“溲”指小便,“便”指大便)。寸口脉的阴阳两部都呈现紧盛之象(寸口即气口,这里指三部脉,关前为阳,关后为阴),大汗出且病不解的,预后不良,会导致死亡;身体发热,呼吸粗重,出现阳脉且躁动的,预后不良,会导致死亡(因为汗出过多不胜病邪)。出汗后仅有轻微发热且病未解的,病情还不能立即断定死亡,但如果脉象像转索一样紧急,当天就会死亡;如果出现谵语、身体微热、脉象浮大、手足温暖的,则有生机,这是因为将要发出大汗的缘故(俗称为“好汗”);如果脉象突然暴出,预后不良,会导致死亡,这是因为阴气衰败欲绝,而阳气突然单独亢盛导致脉象暴出,稍后阴气先绝,阳气随后竭尽而死;如果四肢逆冷,脉象沉细的,不超过一天就会死亡(死证很多,但危急至极的情况没有超出这一范围的)。
Jie Pulse (Knotted Pulse): The pulse is slow and occasionally stops. It belongs to Yin, primarily indicating an excess of Yin causing irritability, restlessness, chest fullness, or deep Yang reversal leading to cold body, a faint pulse nearly imperceptible, and a slow, weak pulse with occasional stops, also associated with chest irritability. This type of stop is due to extreme heat rather than cold, and the root and branch (etiology and symptoms) must be clearly distinguished.
Cu Pulse (Rapid Pulse): The pulse belongs to Yang, being rapid and occasionally stopping. It primarily indicates accumulations, Qi stagnation, and obstruction caused by worry and overthinking; it may also result from severe heat that was not properly purged, leading to a Cu pulse. Purging treatment will normalize the pulse.
Dai Pulse (Intermittent Pulse): Primarily characterized by a slow, weak, and powerless pulse that cannot beat continuously, requiring a pause before beating again. This condition indicates critical illness and likely death.
Fuyang Pulse: This is the pulse reflecting the Stomach Earth. A Fuyang pulse that is slow and moderate indicates that the Stomach Qi is in its normal state (as per the classic channel).
It moves in the meridian of the foot dorsum, hence called Fuyang. Another view states that Chongyang is the Yuan-Source point passed through by the Yangming channel. "Guo" means "chong" (to rush/pass through).
"Ru Jing" refers to the normal pulse of the primary channel.
Hua (Slippery) indicates Stomach Excess, while Jin (Tight) indicates strong Spleen function. A Fu (Floating) and Hua (Slippery) pulse indicates Fu for Stomach Deficiency and Hua for hiccups (Yue). If the pulse is Fu and the nose is dry, epistaxis (Nü) will definitely occur.
Chen (Deep) indicates Stomach Excess (upper deficiency and lower excess), Shu (Rapid) indicates digestion of food (due to Stomach Heat), and Jin (Tight) indicates difficult treatment. Generally, the four seasons and five Zang organs all rely on Stomach Qi as the foundation. If Jin and dryness are excessive while Earth dampness declines, it is said to be difficult to treat. A Fu (Floating) and Da (Large) pulse indicates Qi Excess and Blood Deficiency (Qi is Yang, Blood is Yin). A Fu (Floating) and Se (Choppy) pulse indicates Stomach Deficiency with diarrhea (due to fluid loss causing choppy quality). A Fu (Hidden/Deep) and Se (Choppy) pulse indicates Fu leads to vomiting and regurgitation with undigested food and drink (due to internal dampness); Se indicates Qi cannot descend and no food intake; if the pulse is absent, the body becomes cold and skin hard.
Taixi Pulse: This is the pulse reflecting Kidney Water, moving at the depression behind the medial malleolus of the left foot, below the calcaneus. It is the "Stomach Qi" of the Foot-Shaoyin Kidney Water channel, hence often appearing large and floating. If the Taixi pulse is like the normal channel, Kidney Qi is intact; if weak, there is slight irritability; if choppy, there is cold extremities (mild Jue Ni).
If Yang disease and heat syndrome do not resolve but instead Yin pulses appear, death ensues (because the pulse approaches cessation); if heat resolves after sweating but Yin pulses appear, recovery occurs. When Yin-Yang syndromes and pulses are balanced, the disease heals. In Shanghan (Cold Damage) with coughing and rebellious Qi, if the pulse is San (Scattered), death ensues (due to damage to form); if the pulse is Fu (Floating) and Hong (Surging), sweat is like oil, panting does not cease, fluids and food cannot enter, the body feels numb (numbness implies lack of harmony), alternating between stillness and agitation, this is the end of life; if hair is wet with sweat and panting does not cease, the Lung fails first; if Yang remains alone externally, the body looks like smoked soot, eyes stare straight, and the head shakes, the Heart fails first. If lips and mouth corners turn blue and limbs twitch (Xi, meaning continuous flow, here describing incessant sweating), the Liver fails. If the area around the mouth turns dark yellow with soft/sweaty exudate, the Spleen fails first (Soft means deficient). If urine and stool are incontinent, with delirium and staring eyes, the Kidney fails first (Sou is urination, Bian is defecation). If Cun Kou (Inkwell) pulse Yin and Yang both appear Jin (Tight) and Sheng (Excessive) (Cun Kou is Qi Kou, referring to three positions: anterior to Guan is Yang, posterior is Yin), with profuse sweating that does not resolve, death ensues; if body heat is present, breathing is coarse, Yang pulses appear with agitation, death ensues (sweat cannot overcome the pathogen). If slight heat remains after sweating and the disease does not resolve, death cannot be immediately declared; if the pulse resembles a turning rope, death occurs on that day; if there is delirium, slight body heat, Fu (Floating) and Da (Large) pulse, and warm hands and feet, survival is possible, as this indicates impending profuse sweating (colloquially "good sweat"); if the pulse suddenly bursts forth, death ensues, because Yin decline approaches cessation while Yang suddenly dominates, causing the pulse to burst forth; shortly after, Yin Qi fails first, then Yang Qi exhausts subsequently, leading to death; if there is cold reversal and the pulse is Chen (Deep) and Xi (Fine), death occurs within one day (there are many death signs, but those reaching extreme danger do not exceed these categories).
