脉来急大洪直者死。细微者无害。
脉来乍大乍小。乍短乍长为祸祟。（别本云。右尺洪大为祟脉。）寸尺有脉。关中无脉为鬼
病。
脉浮大者病在外。沉细者病在内。
左手脉横 在右。右手脉横 在左。脉头大者脐上。脉头小者脐下。
浮为风为虚。沉为湿为实。迟为寒为冷。数为热为燥。洪为惊为痫。（一云数为虚为热。滑为
实为下。）
又云。风则脉浮。寒则脉紧。中暑则脉虚而滑。中湿则脉细而涩。（活人书云。脉沉缓为中湿。
脉细者非也。）伤于阴则脉沉。伤于阳则脉浮。
弦紧者可下。弦迟者宜温。紧数者宜汗。脉微者不可吐。虚细者不可下。沉微者不可汗。
人迎脉在左手关前一分。（其穴在结喉两旁同身寸之一寸五分。动脉应手者是也。）诊之以
候六淫。浮则为风。紧盛则伤于寒。
气口脉在右手关前一分。诊之以候七情。浮则为虚为气。紧盛则伤于食。
寒暑燥湿风热谓之六淫。属外因。
喜怒忧思悲恐惊谓之七情。属内因。
疲极筋力。尽神度量、饮食饥饱、叫呼走气、房室劳逸、金疮 折、虎野狼毒虫、鬼疰客忤、
畏压溺等。为不内外因。
陈无择云。凡诊须识人迎气口。以辨内外因。其不与人迎气口相应。为不内外因。所谓关
前一分。人命之主也。
阳病得阴脉者死。阴病得阳脉者生。脉病患不病者死。（名曰行尸）人病脉不病者生。（为
内虚尸厥）既有人病而脉不病者。直是息数脉与相应者可治也。难经云。然人形病脉不病。非有不
病者也。谓息数不应脉数也。脉经云。病患得健脉。名曰卧尸。脉诀云。病患脉健不用治。夫人病
脉不病者。安有是理。当如难经之说。谓息数不应脉数者是也。人之初病。脉非数则迟。必此等
脉可生。若健脉则急大洪直。与形证相反者。断不可治。
脉象来势急迫、宏大、洪大且直挺的，主死证。脉象细微的，无大碍。
脉象忽大忽小，忽短忽长，是遭受邪祟侵扰的表现。（其他版本记载：右尺部脉象洪大为邪祟之脉。）寸部和尺部有脉，而关部和中部无脉，这是鬼病（精神异常或怪病）。
脉象浮大的，病位在体表；脉象沉细的，病位在体内。
左手脉象横溢至右手部位，右手脉象横溢至左手部位。脉头粗大的，病在脐上；脉头细小的，病在脐下。
浮脉主风邪或虚证；沉脉主湿邪或实证；迟脉主寒邪或冷证；数脉主热邪或燥证；洪脉主惊悸或癫痫。（另一种说法认为：数脉主虚和热，滑脉主实和下焦病变。）
又有说法称：风邪致病则脉浮，寒邪致病则脉紧，中暑则脉虚而滑，中湿则脉细而涩。（《活人书》记载：脉沉缓为中湿，脉细并非中湿之象。）伤于阴邪则脉沉，伤于阳邪则脉浮。
弦紧脉可用攻下法；弦迟脉宜用温法；紧数脉宜用发汗法；脉微者不可用吐法；虚细脉不可用攻下法；沉微脉不可用发汗法。
人迎脉位于左手关前一分处。（该穴位在结喉两旁，同身寸一寸五分处，动脉应手即是。）诊察此处以候测六淫（六种外感邪气）。脉浮则为风邪，脉紧盛则为寒邪所伤。
气口脉位于右手关前一分处。诊察此处以候测七情（七种情志变化）。脉浮则为虚证或气滞，脉紧盛则为饮食积滞所伤。
寒、暑、燥、湿、风、热称为六淫，属于外因。
喜、怒、忧、思、悲、恐、惊称为七情，属于内因。
过度劳累筋骨、耗竭心神、饮食饥饱失常、大声呼叫导致气乱、房事劳逸不当、金创骨折、虎狼野犬毒虫咬伤、鬼疰客忤（传染病或惊吓）、恐惧压迫溺水等，属于不内外因。
陈无择说：凡诊脉必须识别人迎和气口，以辨别内外因。如果不与人迎、气口的脉象相应，即为不内外因。所谓“关前一分”，是生命的主宰所在。
阳病出现阴脉的，主死；阴病出现阳脉的，主生。脉象显示病人健康但症状严重的，主死。（称为“行尸”）病人症状严重但脉象平和的，主生。（为内虚导致的尸厥）既然有病人症状严重而脉象平和的情况，只要呼吸次数与脉搏跳动相应，就是可以治疗的。《难经》说：然而人形体有病而脉象无病，并不是真的没有病，而是指呼吸频率与脉搏次数不相适应。《脉经》说：病人得了健旺有力的脉象，称为“卧尸”。《脉诀》说：病人脉象健旺有力，不用治疗。但是，人病了脉象却正常，哪有这个道理？应当像《难经》所说的那样，是指呼吸频率与脉搏次数不相适应的情况。人刚生病时，脉象不是数就是迟，只有这类脉象才可能生还。如果是健旺有力的脉象，则急迫、宏大、洪大、直挺，与形体症状相反的，绝对不可治愈。
When the pulse comes rapid, large, surging, and straight, death ensues. If it is fine and minute, there is no harm.
If the pulse fluctuates between large and small, short and long, it indicates affliction by evil spirits (Gui Bing). (Another version states: A surging and large pulse at the Right Chi position indicates an evil spirit.) If there is a pulse at the Cun and Chi positions but none at the Guan and Zhong positions, it is a disease of ghosts (Gui Bing, referring to psychiatric or strange diseases).
A floating and large pulse indicates disease in the exterior; a deep and fine pulse indicates disease in the interior.
If the Left Hand pulse extends horizontally to the Right side, and the Right Hand pulse extends horizontally to the Left side, it indicates pathology. If the pulse head is large, the disease is above the umbilicus; if the pulse head is small, the disease is below the umbilicus.
Floating indicates Wind or Deficiency; Deep indicates Dampness or Excess; Slow indicates Cold; Rapid indicates Heat or Dryness; Surging indicates Fright or Epilepsy. (Another view holds: Rapid indicates Deficiency and Heat; Slippery indicates Excess and lower jiao pathology.)
It is also said: Wind causes a Floating pulse; Cold causes a Tight pulse; Summerheat causes a Deficient and Slippery pulse; Dampness causes a Fine and Choppy pulse. (*Qin Ren Shu* records: Deep and slow indicates Dampness; Fine is not correct for Dampness.) Injury from Yin pathogens causes a Deep pulse; injury from Yang pathogens causes a Floating pulse.
Chord-like and Tight pulses may be treated with purgation; Chord-like and Slow pulses are suitable for warming; Tight and Rapid pulses are suitable for sweating. Micro-pulses should not be treated with emesis; Deficient and Fine pulses should not be treated with purgation; Deep and Micro pulses should not be treated with sweating.
The Renying (Human Welcome) pulse is located one fen anterior to the Guan on the Left Hand. (This acupoint is located beside the laryngeal prominence, one cun five fen using the same-body measurement method, where the arterial pulse can be felt.) Diagnosis here monitors the Six Evils (Liu Yin, six external pathogenic factors). Floating indicates Wind; Tight and vigorous indicates Cold injury.
The Qikou (Qi Mouth) pulse is located one fen anterior to the Guan on the Right Hand. Diagnosis here monitors the Seven Emotions (Qi Qing, seven emotional factors). Floating indicates Deficiency or Qi stagnation; Tight and vigorous indicates food retention.
Cold, Summerheat, Dryness, Dampness, Wind, and Heat are called the Six Evils, belonging to External Causes.
Joy, Anger, Worry, Thought, Sorrow, Fear, and Fright are called the Seven Emotions, belonging to Internal Causes.
Exhaustion of sinews and muscles, depletion of mental energy, irregular diet (hunger and fullness), shouting causing Qi dispersion, sexual activity and labor/rest imbalance, metal wounds and fractures, bites from tigers, wolves, wild dogs, and poisonous insects, Gui Zhu Ke Wu (infectious diseases or fright), fear, compression, drowning, etc., belong to Neither Internal nor External Causes.
Chen Wuyue stated: In all diagnoses, one must recognize the Renying and Qikou pulses to distinguish internal and external causes. If they do not correspond with the Renying and Qikou, it is a Neither Internal nor External Cause. The so-called "one fen anterior to the Guan" is the master of human life.
Yang diseases presenting with Yin pulses indicate death; Yin diseases presenting with Yang pulses indicate survival. When the pulse suggests health but the patient is severely ill, death ensues (called "Walking Corpse"). When the patient is severely ill but the pulse is normal, survival is indicated (Internal Deficiency leading to Shi Jue/Corpse Syncope). Since there are cases where the patient is ill but the pulse is normal, if the respiration rate corresponds with the pulse rate, it is treatable. *Nan Jing* states: Although the body shows disease while the pulse does not, this is not true absence of disease, but rather that the respiration rate does not correspond with the pulse rate. *Mai Jing* states: When a patient has a robust pulse, it is called "Woh Shi" (Lying Corpse). *Mai Jue* states: If the patient's pulse is robust, no treatment is needed. However, how can it be that a person is ill yet the pulse is normal? One should follow the explanation of *Nan Jing*, which refers to the mismatch between respiration rate and pulse rate. At the onset of illness, the pulse is either Rapid or Slow; only such pulses allow for survival. If the pulse is robust—rapid, large, surging, and straight—and contradicts the physical symptoms, it is absolutely untreatable.
