常有死后一日半日，气口脉犹动者，此惟富贵人多有之。其故由于平日颐养丰浓，所谓

多用物宏，魂气深固难散；或病中多服人参，摄其无根虚阳，结于胸中，不得遽散也。故少
年急病，及强死之人，有半日身温者，亦以生气未尽也。更有死后暂复回生者，身凉无脉，

常有死后一日或半日，气口脉（手腕桡动脉处）仍然跳动的情况，这多见于富贵人家。其原因在于平日生活优渥、饮食丰盛，即所谓“取精多用物宏”，导致魂气深固难以消散；或者在患病期间服用人参过多，摄纳了无根的虚阳，结聚于胸中，不能迅速消散。因此，少年患急病去世的人，以及非正常死亡的人，死后半天身体仍有余温，也是因为生机尚未完全耗尽。更有甚者，死后暂时复活回生的人，虽然身体变凉且无脉搏，但神志清明，言语条理清晰，甚至比平时更胜一筹，这是游魂作祟所致，这种情况也只见于少年含冤而死或志向奢大未得实现的人。这些情况都与延请医生救治无关，但其中的道理不可不知。
胎脉的变化最为繁多，《脉经》总以阴阳呼吸均匀为主旨。然而近来我曾诊察到一种细弱且两旁涣散有晕感，一息跳动五次以上，来势盛而去势衰，仅在浮取和中取时能感觉到，重按则空虚无根，仔细审察举按之间，指下微微感到滑疾，全似血虚气燥之脉。这种血虚有热的妇女，怀孕一两个月时多见此脉。如果仅凭脉象判断，不知道是怀孕，也必然会用甘酸之剂来滋养，这样才能保证不流产。鬼胎脉，我曾诊察过一个人，其尺部脉沉细而急促，指下感觉似滑，脉位短居关后，不能上达寸部，三部脉都不上扬，起伏很小。诊察时正值怀孕八九月，脉象却只像初孕二三个月的样子，没有其他奇怪之处，气血不急促的妇女，多有此脉。当时并不知道是鬼胎，后来她屡次腹痛欲产，腹部逐渐消瘦缩小，也没有其他疾病。
王汉皋说：有开始怀孕不到十天半月，其人出现狂躁厥逆几乎要死去的情况，只是时发时止，发作时如病危，停止时则如常人，这就必须防备是有孕在身，但未明确说明导致这种情况的原因。通过历次验证所诊察的早期怀孕案例，怪脉和怪证非常多见。其症状有的极度寒冷战栗，有的极度热如火焚，有的气短几乎断绝，有的汗出不止，有的全身发斑，有的腹痛如被揪扯。其脉象有的某一部脉不见，有的某一部脉坚硬搏指，有的忽来忽止，形状如雀啄食，有的时而大时而小，早晚不定。推究其根本原因，都是在受孕之时，正值劳累疲倦，或正值醉酒饱食，正值饥渴，或正值风寒凉爽，正值暑热，或正值惊恐，或正值忧虑，或正值愤怒，或素体血虚，月经后肝燥，津液未恢复就立即怀孕，或睡眠不足突然惊醒，血液未归于心。这些都是正气未复，就立即受孕，各种邪气随即挟带进入胎元。胞脉联络心脏，其气相互感应，所以出现各种脉象和症状。私通所怀之胎多有此象，因为其神明不安定。怀孕两三个月后，邪气逐渐消散，正气逐渐恢复，这些现象就不见了。也有必须用药调理的，否则有损伤堕胎的忧虑。
There are cases where the Qi Kou pulse (pulse at the radial artery of the wrist) still beats one or half a day after death; this is mostly seen in people from wealthy and noble families. The reason lies in their daily luxurious life and rich diet, known as "extracting essence while using much," which causes the Hun Qi (ethereal soul energy) to be deeply rooted and difficult to dissipate; or it may be due to excessive consumption of Ginseng Radix et Rhizoma (Renshen, 人参) during illness, which captures the rootless deficient Yang, causing it to knot in the chest and not dissipate quickly. Therefore, young people who die from acute diseases, as well as those who suffer violent deaths, may have warm bodies for half a day after death because the Sheng Qi (vital energy) has not yet completely exhausted. Even more rarely, some temporarily revive after death; although their bodies become cool and pulseless, their Shen Qi (spiritual energy) is clear, their speech is coherent and reasonable, sometimes even surpassing their usual state; this is caused by wandering Hun acting up, and it only occurs in youths who died unjustly or whose ambitious desires were unfulfilled. These situations are unrelated to seeking medical treatment, but the principles behind them must be understood.
Fetal pulses (Tai Mai, 胎脉) exhibit the most variations; the *Mai Jing* (Pulse Classic) generally emphasizes the uniformity of Yin and Yang respiration. However, recently I examined a case where the pulse was fine and weak, with a scattered halo on both sides, beating more than five times per breath, with a strong arrival and weak departure, perceptible only at superficial (Fu, 浮) and middle (Zhong, 中) depths, feeling empty upon deep pressure (Chen, 陈). Carefully observing between lifting and pressing, the fingers felt slightly slippery and rapid, resembling entirely the pulse of Blood deficiency and Qi dryness. This type of pulse is commonly seen in women with Blood deficiency and Heat during the first one or two months of pregnancy. If judged solely by the pulse without recognizing pregnancy, one would inevitably prescribe Sweet and Sour formulas to nourish, thereby ensuring the prevention of miscarriage. Regarding Ghost Fetus pulse (Gui Tai Mai, 鬼胎脉), I once examined a patient whose Chi pulse (Kidney pulse) was deep, fine, and rapid, feeling slippery under the fingers, positioned short behind the Guan (Cun-Guan-Chi system), unable to reach the Cun position. All three positions lacked elevation, with very small fluctuations. At the stage of eight or nine months of pregnancy, the pulse resembled that of early pregnancy (two to three months), with no other abnormalities; women with non-rushed Qi and Blood often present this pulse. At the time, I did not know it was a ghost fetus; later, she experienced repeated abdominal pain and urge to deliver, while her abdomen gradually shrank and wasted away, with no other illnesses.
Wang Hangan stated: There are cases where, less than ten days or half a month after conception, the person experiences mania and cold limbs almost leading to death, occurring intermittently; during attacks, they appear critically ill, but when symptoms cease, they return to normal. One must suspect pregnancy, though the cause was not explicitly stated. Through repeated verification of diagnosed early pregnancies, abnormal pulses and symptoms are numerous. Symptoms include extreme internal chills, extreme heat like burning, shortness of breath nearly ceasing, continuous sweating, generalized macules, or abdominal pain as if being squeezed. Pulses may show absence in one position, hardness and pounding in one position, sudden cessation resembling bird pecking, or fluctuating size irregularly. Tracing the root cause, these occur when conception happens during fatigue, drunkenness or overeating, hunger or thirst, wind and cold, summer heat, fright, worry, anger, or when the constitution is inherently Blood deficient, Liver dry after menstruation, fluids not restored before conception, or waking abruptly from insufficient sleep with Blood not returning to the Heart. In all these cases, Zheng Qi (Upright Qi) has not recovered before conception, allowing various pathogenic Qi to enter the fetus along with it. Since the Bao Mai (uterine vessels) connect to the Heart, their Qi interacts, resulting in these various pulse and symptom manifestations. Illicit pregnancies often present this image due to unstable Shen Ming (spiritual clarity). After two or three months, as pathogenic Qi dissipates and Zheng Qi recovers, these phenomena disappear. Some cases require medicinal regulation; otherwise, there is a risk of injury or miscarriage.
