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。
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.
