心象火，与小肠合为腑（小肠为受盛之腑也）。其经手少阴（手少阴心脉也），与手太阳为表里（手太阳小肠脉也）。
其脉洪（洪，心脉之大形），其相春三月（木王火相），王夏三月，废季夏六月，囚秋三月（金王火囚），死冬三月（水王
火死）。其王日丙丁，王时禺中、日中；其困日庚辛，困时晡时、日入，其死日壬癸，死时人定、夜半。其藏神（心之所
藏者神也），其主臭，其养血（心气所养者血），其候舌，其声言（言由心出，故主言），其色赤，其臭焦，其液汗，其味
苦，其宜甘（甘，脾味也），其恶咸（咸，肾味也）。心俞在背第五椎（或云第七椎），募在巨阙（在心下一寸），小肠俞
在背第十八椎，募在关元。（脐下三寸）上新撰。
心者南方火（心主血，其色赤，故以夏王于南方，应火行）。万物洪盛，垂枝布叶，皆下垂如曲，故名曰钩（心王之
时，太阳用事，故草木茂盛，枝叶布舒，皆下垂曲。故谓之钩也）。心脉洪大而长，洪则卫气实，实则气无从出（脉洪者
卫气实，卫气实则腠理密，密则气无从出）。大则荣气萌，萌洪相薄，可以发汗，故名曰长（荣者血也，萌当为明字之误
耳，血王故明且大也。荣明卫实，当须发动，通其津液也）。长洪相得，即引水浆，溉灌经络，津液皮肤（夏热阳气盛，
故其人引水浆，润灌肌肤，以养皮毛，犹草木须雨泽以长枝叶）。太阳洪大，皆是母躯，幸得戊己，用牢根株（太阳夏火，
春木为其母。阳得春始生，名曰少阳。到夏洪盛，名曰太阳，故言是母躯也。戊己土也，土为火子，火王即土相，故用
牢根株也）。阳气上出，汗见于头。五月枯HT ，胞中空虚，医反下之，此为重虚也（月当为内，HT 当为干，枯燥也。
皆字误耳。内字似月，由来远矣，遂以传焉，人头者，诸阳之会。夏时饮水浆，上出为汗，先从头流于身躯，以实其表，
是以五内干枯，燥则胞中空虚津液少也。胞者膀胱，津液之腑也。愚医不晓，故反下之，令重虚也）。脉浮有表无里，阳
无所使（阳盛脉浮，宜发其汗，而反下之，损于阴气。阳为表，阴为里。《经》言∶阳为阴使，阴为阳守，相须而行。
脉浮，故无里也。治之错逆，故令阴阳离别，不能复相朝使）。不但危身，并中其母。（言下之不但伤心，并复中肝）
上四时经。
黄帝问曰∶夏脉如钩，何如而钩？岐伯曰∶夏脉心也，南方火也，万物之所以盛长也。故其气来盛去衰，故曰钩，
反此者病，黄帝曰∶何如而反？岐伯曰∶其气来盛去亦盛，此谓太过，病在外；其来不盛去反盛，此谓不及，病在中。
黄帝曰∶夏脉太过与不及，其病皆何如？岐伯曰∶太过则令人身热而肤痛，为浸淫；不及则令人烦心，上见咳唾，下为
气泄。帝曰∶善。
心脉来累累如连珠，如循琅 ，曰平。夏以胃气为本。心脉来喘喘（《甲乙》作累累）连属，其中微曲，曰心病。心
脉来前曲后居，如操带钩，曰心死。
真心脉至，坚而搏，如循薏苡子，累累然，其色赤黑不泽，毛折，乃死。夏胃微钩曰平，钩多胃少曰心病，但钩无
胃曰死。胃而有石曰冬病，石甚曰今病。心藏脉，脉舍神。怵惕思虑则伤神，神伤则恐惧自失，破KT 脱肉，毛悴色夭，
死于冬。夏心火王，其脉洪（《千金》作浮大而洪）大而散，名曰平脉。反得沉濡而滑者，是肾之乘心，水之克火，为贼
邪，大逆，十死不治（一本云∶日、月、年数至二，忌壬癸）。反得大而缓者，是脾之乘心，子之扶母，为实邪，虽病自
愈。反得弦细而长者，是肝之乘心，母之归子，为虚邪，虽病易治。反得浮（《千金》浮作微）涩而短者，是肺之乘心。
金之陵火，为微邪，虽病即瘥。
心脉来累累如贯珠滑利，再至，曰平；三至，曰离经，病；四至，脱精；五至，死；六至，命尽，手少阴脉。
心脉急甚，为螈 ；微急，为心痛引背，食不下。缓甚为狂笑；微缓，为伏梁，在心下，上下行，时唾血。大甚，

心脏在五行中属火，与小肠相合构成腑（小肠是接受和盛纳食物的腑）。其经脉为手少阴心经（手少阴心脉），与手太阳小肠经互为表里（手太阳小肠脉）。
该脉象表现为洪大（洪，是心脉盛大之象），对应春季三月（木旺火相），旺于夏季三月，废于季夏六月，囚于秋季三月（金旺火囚），死于冬季三月（水旺火死）。其旺日为丙、丁日，旺时为上午九时至中午十二时；其困日为庚、辛日，困时为下午三时至日落时分；其死日为壬、癸日，死时为黄昏至半夜。心藏神（心所藏的是神志），主嗅觉（此处原文有误，通常心主舌/味，但依原文翻译），养血液（心气所滋养的是血），外候于舌，发声为言（言语由心发出，故心主言语），面色为赤，气味为焦，体液为汗，味道为苦，适宜甘味（甘，是脾的味道），厌恶咸味（咸，是肾的味道）。心俞穴位于背部第五椎旁（也有说法是第七椎），募穴在巨阙穴（心下上一寸）；小肠俞穴位于背部第十八椎旁，募穴在关元穴（脐下三寸）。以上为新近编纂的内容。
心属于南方之火（心主血，其色赤，所以在夏季旺盛于南方，对应火行）。万物茂盛，枝叶下垂弯曲，所以称为“钩”（心王之时，太阳用事，所以草木茂盛，枝叶舒展，都下垂弯曲，所以叫作钩）。心脉洪大而长，洪表示卫气充实，充实则气无法外出（脉象洪大是因为卫气实，卫气实则腠理致密，致密则气无法外出）。大表示荣气萌动，萌动与洪大相互搏结，可以发汗，所以称为“长”（荣即血，萌当为明字之误，血旺所以明亮且大。荣明卫实，应当发动，通畅津液）。长与洪相得，就会引用水浆，灌溉经络，滋润皮肤（夏季炎热阳气盛，所以人想喝水浆，润灌肌肤，以养皮毛，就像草木需要雨水来生长枝叶一样）。太阳洪大，都是母体之躯，幸好得到戊己土的帮助，用来牢固根株（夏季太阳火，春季木为其母。阳从春始生，名叫少阳。到了夏天洪盛，名叫太阳，所以说这是母体。戊己是土，土是火的子，火旺则土相，所以用来牢固根株）。阳气向上外出，汗见于头部。五月内干枯，胞中空虚，医生反而使用下法，这是双重虚弱（月当为内，HT当为干，指枯燥。都是字误。内字似月，由来已久，于是流传下来。人头是诸阳之会。夏季饮水浆，上出为汗，先从头部流到身躯，以充实体表，因此五内干枯，燥则胞中空虚津液少。胞指膀胱，是津液之腑。愚医不懂，反而用下法，导致双重虚弱）。脉浮有表无里，阳无所使（阳盛脉浮，宜发其汗，而反用下法，损伤阴气。阳为表，阴为里。《经》说：阳为阴使，阴为阳守，相互依存而行。脉浮，所以无里。治疗错误逆乱，所以令阴阳离别，不能互相朝使）。不仅危及自身，还会伤害其母。（意思是下法不仅伤心，还会伤肝）。以上出自四时经。
黄帝问道：夏脉像钩，什么样的脉象叫钩？岐伯说：夏脉对应心，属南方火，是万物盛长的时节。所以其气来时盛而去时衰，所以叫钩，与此相反的就是病。黄帝问：怎样算是相反？岐伯说：其气来时盛去时也盛，这叫太过，病在外；其气来不盛去反而盛，这叫不及，病在中。黄帝问：夏脉太过与不及，它们的病症各是什么？岐伯说：太过则让人身体热而皮肤痛，发生浸淫疮；不及则让人心烦，上面出现咳嗽吐痰，下面出现气泄。帝说：好。
心脉来累累如连珠，像抚摸琅玕玉一样，称为平脉。夏季以胃气为本。心脉来喘喘（《甲乙经》作累累）相连属，其中微曲，称为心病。心脉来前曲后居，像拿着带钩的腰带一样，称为心死。
真心脉至，坚硬而搏指，像抚摸薏苡子，累累然，其色赤黑无光泽，毛发折断，就会死亡。夏季胃气微钩称为平脉，钩多胃少称为心病，只有钩没有胃气称为死。胃气中有石脉称为冬季有病，石脉甚重称为现在有病。心藏脉，脉舍神。惊恐思虑会伤神，神伤则恐惧自失，肌肉消瘦脱肉，毛悴色夭，死于冬季。夏季心火旺，其脉洪（《千金方》作浮大而洪）大而散，称为平脉。反而得到沉濡而滑的脉，是肾乘心，水克火，为贼邪，大逆，十死不治（另一版本说：日、月、年数至二，忌壬癸日）。反而得到大而缓的脉，是脾乘心，子扶母，为实邪，虽然生病会自动痊愈。反而得到弦细而长的脉，是肝乘心，母归子，为虚邪，虽然生病容易治。反而得到浮（《千金方》浮作微）涩而短的脉，是肺乘心。金凌火，为微邪，虽然生病即刻痊愈。
心脉来累累如贯珠滑利，两至，称为平；三至，称为离经，病；四至，脱精；五至，死；六至，命尽，这是手少阴脉。
心脉急甚，为抽搐；微急，为心痛牵引背部，饮食不下。缓甚为狂笑；微缓，为伏梁，在心下，上下移动，时常唾血。大甚，为喉痹；微大，为心痹牵引背部，容易流泪。小甚，为善哕；微小，为消瘅。滑甚，为善渴，微滑，为心疝牵引脐部，小腹鸣响；涩甚，为喑哑；微涩，为血溢，四肢厥冷，耳鸣，巅顶疾病。手少阴气绝则脉不通。少阴，是心脉。心，是脉的合应。脉不通则血不流，血不流则发色不泽，所以面色黑如漆柴，是血先死。壬日笃重，癸日死，因为水胜火。心死脏，轻取脉实，如豆麻击手，重按更躁疾的，死。以上出自《素问》《针经》、张仲景。
The Heart corresponds to Fire and combines with the Small Intestine to form a Fu organ (the Small Intestine is the Fu organ of reception and storage). Its meridian is the Hand-Shaoyin Heart Meridian (Hand-Shaoyin Heart pulse), which is exterior-interior related to the Hand-Taiyang Small Intestine Meridian (Hand-Taiyang Small Intestine pulse).
Its pulse is Hong (Hong refers to the large shape of the Heart pulse), corresponding to the three months of Spring (Wood is Wang, Fire is Xiang), Wang in the three months of Summer, Fei in the sixth month of late Summer, Qiu in the three months of Autumn (Metal is Wang, Fire is Qiu), and Si in the three months of Winter (Water is Wang, Fire is Si). Its Wang days are Bing and Ding days, Wang hours are from 9:00 AM to 12:00 PM; its Kun days are Geng and Xin days, Kun hours are from 3:00 PM to sunset; its Si days are Ren and Gui days, Si hours are from dusk to midnight. The Heart stores Shen (Shen is what the Heart stores), governs smell (note: text says "smell", though traditionally Heart governs taste/speech), nourishes Blood (Blood is what Heart Qi nourishes), manifests on the tongue, and produces speech (speech originates from the Heart, so it governs speech). Its color is Red, its odor is Scorched, its fluid is Sweat, its taste is Bitter, it favors Sweet (Sweet is the taste of the Spleen), and it dislikes Salty (Salty is the taste of the Kidney). Xinshu (Heart Shu point) is located at the fifth thoracic vertebra on the back (some say the seventh), and its Mu point is Juque (one cun below the heart); Xiaochangshu (Small Intestine Shu point) is located at the eighteenth thoracic vertebra on the back, and its Mu point is Guanyuan (three cun below the umbilicus). This is newly compiled.
The Heart belongs to Fire in the South (The Heart governs Blood, its color is Red, thus it is Wang in the South during Summer, corresponding to the Fire element). All things are abundant and flourishing; branches hang down and leaves spread out, all curving downwards, hence named "Gou" (Hook) (When the Heart is Wang, Taiyang is in charge, so grass and trees flourish, branches and leaves spread and curve downwards. Hence it is called Hook). The Heart pulse is Hong, large, and long. Hong indicates that Wei Qi (Defensive Qi) is solid; when solid, Qi has no outlet (A Hong pulse means Wei Qi is solid; when Wei Qi is solid, the couli [pores] are dense; when dense, Qi cannot exit). Large indicates that Ying Qi (Nutritive Qi) is bright/vigorous; when vigorous and Hong interact, sweating can be induced, hence named "Long" (Ying is Blood; "Meng" should be a typo for "Ming"; when Blood is Wang, it is bright and large. When Ying is bright and Wei is solid, movement must be initiated to unblock fluids). When Long and Hong are harmonious, water and fluids are drawn in to irrigate the meridians and moisten the skin (Summer heat and Yang Qi are abundant, so people desire water/fluids to moisten the body and nourish hair and skin, just as grass and trees need rain to grow branches and leaves). Taiyang Hong and Large are both maternal bodies; fortunately aided by Wu and Ji Earth, they use firm rootstocks (Summer Taiyang Fire, Spring Wood is its mother. Yang begins to generate in Spring, named Shaoyang. In Summer, it becomes abundant and large, named Taiyang, hence called maternal body. Wu and Ji are Earth; Earth is the child of Fire; when Fire is Wang, Earth is Xiang, hence used to firm the rootstock). Yang Qi emerges upward, sweat appears on the head. In the fifth month, the interior dries up, the Bao (Bladder) is empty; if the physician incorrectly uses purgation, this constitutes double deficiency (Month should be Nei [Interior]; HT should be Gan [Dry], meaning dryness. These are character errors. The character Nei resembles Yue [Moon], and has been transmitted thus for a long time. The head is the convergence of all Yang Qi. In Summer, drinking fluids leads to sweat emerging upward, first flowing from the head to the body to fill the exterior, thus the five viscera become dry; dryness causes the Bao to be empty with little fluid. Bao refers to the Bladder, the Fu organ of fluids. Ignorant physicians do not understand and incorrectly use purgation, causing double deficiency). A floating pulse indicates Exterior without Interior, Yang has no function (Yang excess causes a floating pulse; sweating is appropriate, but purgation was incorrectly used, damaging Yin Qi. Yang is Exterior, Yin is Interior. The Classic states: Yang is the servant of Yin, Yin is the guardian of Yang, they act together. A floating pulse means no Interior. Incorrect treatment causes Yin and Yang to separate, unable to mutually serve). This not only endangers the body but also harms its Mother (Meaning purgation not only damages the Heart but also injures the Liver). From the Four Seasons Classic.
The Yellow Emperor asked: The summer pulse is like a hook; what makes it a hook? Qibo said: The summer pulse corresponds to the Heart, which is Fire in the South, the season when all things flourish and grow. Thus, its Qi comes strong and departs weak, hence called Hook. Opposite to this is disease. The Yellow Emperor asked: How is it opposite? Qibo said: If its Qi comes strong and departs strong, this is called Excess, disease is in the Exterior; if it comes weak and departs strong, this is called Deficiency, disease is in the Interior. The Yellow Emperor asked: For summer pulse Excess and Deficiency, what are their diseases? Qibo said: Excess causes fever and skin pain, leading to spreading sores; Deficiency causes vexation, upper coughing and spitting, lower qi leakage. The Emperor said: Excellent.
If the Heart pulse comes like pearls linked together, smooth like touching Langgan jade, it is a Ping (Normal) pulse. Summer relies on Stomach Qi as the foundation. If the Heart pulse comes panting-like (Jia Yi Jing reads "lei lei") continuously, slightly curved within, it is Heart Disease. If the Heart pulse comes curved at the front and stationary at the back, like handling a belt hook, it is Heart Death.
When the True Heart pulse arrives, it is hard and beating, like touching Coix seeds, continuous; if the color is red-black and lusterless, and hair breaks, death ensues. Summer with slight Stomach Qi and Hook is Ping; more Hook than Stomach Qi is Heart Disease; only Hook without Stomach Qi is Death. Stomach Qi with Stone pulse indicates Winter disease; severe Stone pulse indicates current disease. The Heart stores Pulse, and Pulse houses Shen. Fear and worry damage Shen; damaged Shen leads to fear and loss of self-control, emaciation, lusterless hair and complexion, dying in Winter. In Summer, Heart Fire is Wang; its pulse is Hong (Qian Jin Fang reads "floating, large, and Hong"), large and scattered, named Ping Pulse. If instead a sinking, soft, and slippery pulse is obtained, this is Kidney overcoming Heart, Water overcoming Fire, constituting Zhi Xie (Robber Evil), great reversal, ten deaths untreatable (One version says: Day, Month, Year count reaches two, avoid Ren and Gui days). If instead a large and slow pulse is obtained, this is Spleen overcoming Heart, Child supporting Mother, constituting Shi Xie (Solid Evil); although ill, it will recover spontaneously. If instead a string-like, thin, and long pulse is obtained, this is Liver overcoming Heart, Mother returning to Child, constituting Xu Xie (Empty Evil); although ill, it is easy to treat. If instead a floating (Qian Jin Fang reads "slight") choppy and short pulse is obtained, this is Lung overcoming Heart. Metal bullying Fire, constituting Wei Xie (Minor Evil); although ill, it heals immediately.
If the Heart pulse comes continuous like beads, smooth and slippery, two beats per respiration, it is Ping; three beats, Li Jing (Departing from the Channel), disease; four beats, Jing Depletion; five beats, Death; six beats, Life Exhausted. This is the Hand-Shaoyin pulse.
If the Heart pulse is extremely urgent, it is convulsion; slightly urgent, it is Heart pain radiating to the back, inability to eat. Extremely slack is maniacal laughter; slightly slack is Fu Liang (Hidden Beam) below the heart, moving up and down, occasional hemoptysis. Extremely large is throat obstruction; slightly large is Heart Bi radiating to the back, prone to tearing. Extremely small is frequent hiccups; slightly small is Xiao Dan (Wasting-Thirst). Extremely slippery is excessive thirst; slightly slippery is Heart Han radiating to the umbilicus, abdominal borborygmus. Extremely choppy is aphonia; slightly choppy is blood extravasation, limb coldness, tinnitus, and vertex disease. When Hand-Shaoyin Qi perishes, the pulse does not flow. Shaoyin is the Heart pulse. The Heart is the union of the pulse. If the pulse does not flow, blood does not circulate; if blood does not circulate, hair loses luster; thus, if the face is black like lacquered charcoal, blood has died first. Ren day is critical, Gui day is death, because Water overcomes Fire. Heart death organ: superficial pulse is solid, like beans hitting the hand; deep pulse is even more restless, death.
