五脏病脉扁鹊曰。脉长而弦。病出于肝。脉大而洪。病出于心。脉下坚上虚。病出于脾。脉涩而浮。病出于肺。脉
小而挛。病出于肾。
四时病脉。经。春不沉。夏不弦。秋不数。冬不涩。是谓四塞。（如春水旺。其脉弦。然春初之时。兼冬脉。而沉弦。
则水生木。母子之气相通也。若弦而不沉。是不得母气。故曰塞。塞则病矣）参见曰病。（如春脉弦。参见他脉。则他脏
之气乘肝也。）未去而去曰病。（如春脉弦未交夏之时。便不见弦而见钩。是肝气不足。未当去而即去也。）去而不去曰病。
（如春脉弦。入夏已深。仍见弦不见钩。是肝气有余。当去而不去也。）复见曰病。（如春脉弦。或秋时复见弦脉。是肝
之乘肺也。）
三部病脉。脉经寸脉浮大而疾者。名曰阳中之阳。（寸阳部也。浮大疾。阳脉也。故曰阳中之阳。）病苦烦满。身热
头痛。腹中热。寸脉沉细者。名曰阳中之阴。（沉细阴脉也。见寸阳部。故曰阳中之阴。）病苦悲伤不乐。恶闻人声。少
气。时汗出。阴气不通。臂不能举。尺脉沉细者。名曰阴中之阴。病苦两胫酸痛。不能久立。阴气衰。小便余涩。阴下
湿痒。尺脉滑而浮大者。名曰阴中之阳。病若小腹痛。满不能溺。溺即阴中痛。大便亦然。寸脉壮大。尺中无有。此为
阳干阴。其人若腰背痛。阴中伤。足胫寒。尺脉牢而长。关上无有。此为阴干阳。其人若两胫重。少腹引臀痛。上鱼际

五脏病脉：扁鹊说，脉象长而弦，病出于肝；脉象大而洪，病出于心；脉象下部坚实上部虚弱，病出于脾；脉象涩而浮，病出于肺；脉象小而拘挛，病出于肾。
四时病脉：《经脉》篇记载，春季脉象不沉，夏季脉象不弦，秋季脉象不数（快），冬季脉象不涩，这称为“四塞”。（例如春季水气旺盛，其脉应呈弦象，但在初春时节，兼有冬季的脉象，表现为沉弦，这是水生木，母子之气相通。如果只有弦象而没有沉象，说明得不到母气的滋养，所以称为“塞”，闭塞则生病。）参见曰病。（例如春季脉象应弦，若见到其他脉象，则是他脏之气乘袭肝脏。）未去而去曰病。（例如春季脉象为弦，在尚未进入夏季之时，便不见弦象而见钩象，这是肝气不足，未到该退去的时候却提前退去了。）去而不去曰病。（例如春季脉象为弦，进入夏季已深，仍见弦象而不见钩象，这是肝气有余，到了该退去的时候却没有退去。）复见曰病。（例如春季脉象为弦，若在秋季又见到弦脉，这是肝气乘袭肺脏。）
三部病脉：《经脉》篇记载，寸口脉浮大且疾速的，称为阳中之阳。（寸部属阳，浮、大、疾均为阳脉，故称阳中之阳。）病症表现为心中烦闷胀满，身体发热，头痛，腹中热。寸口脉沉细的，称为阳中之阴。（沉细为阴脉，出现在寸部阳位，故称阳中之阴。）病症表现为悲伤不乐，厌恶听到人声，气短，时常出汗，阴气不通畅，手臂不能举起。尺部脉沉细的，称为阴中之阴。病症表现为两小腿酸痛，不能久站，阴气衰弱，小便余沥涩痛，阴部潮湿瘙痒。尺部脉滑而浮大的，称为阴中之阳。病症表现为小腹痛，胀满不能排尿，排尿时尿道疼痛，大便亦然。寸口脉壮大，而尺部脉无此象，这叫阳干阴（阳邪侵犯阴分）。其人若腰背疼痛，阴部受伤，足胫寒冷。尺部脉牢而长，关部脉无此象，这叫阴干阳（阴邪侵犯阳分）。其人若两腿沉重，小腹牵引臀部疼痛。
上鱼际病脉：《经脉》篇记载，脉气侵入鱼际部位的，会出现遗尿；脉气出鱼际部位的，会出现气逆喘息。
外内久新病：《经脉》篇记载，脉象浅表、滑利、坚硬的，病在外表；脉象细小、实而坚硬的，病在内里；脉象细小、弱而涩的，称为久病；脉象浮、滑且疾速的，称为新病。六病脉：《经脉》篇记载，弦、紧、滑、涩、浮、沉这六种脉象属于残贼之脉，能导致各经络产生疾病。
Pulse Patterns of the Five Zang Organs: Bian Que stated that a pulse that is long and wiry indicates disease originating in the Liver; a pulse that is large and surging indicates disease originating in the Heart; a pulse that is firm below and deficient above indicates disease originating in the Spleen; a pulse that is choppy and floating indicates disease originating in the Lung; a pulse that is small and cramped indicates disease originating in the Kidney.
Seasonal Pulse Patterns: The *Mai Jing* (Classic of Pulses) states that if the spring pulse is not deep, the summer pulse is not wiry, the autumn pulse is not rapid, and the winter pulse is not choppy, this is called "Four Obstructions" (Si Sai). (For example, in spring, Water Qi is abundant, so the pulse should be wiry. However, in early spring, it combines with the winter pulse, appearing deep and wiry, indicating that Water generates Wood, and the mother-child Qi are connected. If the pulse is wiry but not deep, it fails to receive the nourishment of the mother Qi, hence termed "Obstruction." Obstruction leads to disease.) "Jian Can" (Seeing Another) is called disease. (For example, if the spring pulse should be wiry but another pulse is seen, it indicates that the Qi of another Zang organ is invading the Liver.) "Wei Qu Er Qu" (Departing Before Its Time) is called disease. (For example, if the spring pulse is wiry, but before entering summer, the wiry pulse disappears and the hook-like pulse appears, this indicates Liver Qi deficiency; it departed when it should not have.) "Qu Er Bu Qu" (Remaining After Its Time) is called disease. (For example, if the spring pulse is wiry, but deep into summer, the wiry pulse remains while the hook-like pulse does not appear, this indicates Liver Qi excess; it remained when it should have departed.) "Fu Jian" (Reappearing) is called disease. (For example, if the spring pulse is wiry, but a wiry pulse reappears in autumn, this indicates Liver Qi invading the Lungs.)
Pulse Patterns of the Three Positions: The *Mai Jing* states that a Cun (Inch) position pulse that is floating, large, and rapid is named Yang within Yang. (The Cun position belongs to Yang; floating, large, and rapid are all Yang pulses, hence Yang within Yang.) The symptoms include vexation and fullness, body heat, headache, and heat in the abdomen. A Cun position pulse that is deep and fine is named Yang within Yin. (Deep and fine are Yin pulses appearing in the Yang position of Cun, hence Yang within Yin.) The symptoms include sorrow and unhappiness, aversion to hearing voices, shortness of breath, spontaneous sweating, obstruction of Yin Qi, and inability to raise the arms. A Chi (Cubit) position pulse that is deep and fine is named Yin within Yin. The symptoms include soreness and pain in both calves, inability to stand for long periods, deficiency of Yin Qi, dribbling and difficult urination, and dampness and itching in the genital region. A Chi position pulse that is slippery and floating-large is named Yin within Yang. The symptoms include lower abdominal pain, fullness, inability to urinate, and pain in the urethra during urination, as well as similar issues with defecation. If the Cun pulse is strong and large while the Chi pulse lacks this quality, it is called Yang interfering with Yin. The person may suffer from backache, injury to the genitalia, and coldness in the feet and calves. If the Chi pulse is firm and long while the Guan (Bar) pulse lacks this quality, it is called Yin interfering with Yang. The person may suffer from heaviness in both legs and pain radiating from the lower abdomen to the buttocks.
Pulse Patterns at the Thenar Eminence (Yu Ji): The *Mai Jing* states that if the pulse extends into the Yu Ji (thenar eminence), it causes urinary incontinence; if the pulse emerges from the Yu Ji, it causes rebellious Qi and panting.
Diseases of Exterior/Interior and Chronic/Acute: The *Mai Jing* states that a pulse that is superficial, slippery, and firm indicates disease in the exterior; a pulse that is small, solid, and firm indicates disease in the interior; a pulse that is small, weak, and choppy is termed chronic disease; a pulse that is floating, slippery, and rapid is termed acute disease. Six Disease-Producing Pulses: The *Mai Jing* states that the wiry, tight, slippery, choppy, floating, and deep pulses are considered "deleterious" (Can Ze) pulses, which can cause disease in the various meridians.
