The happy pulse usually refers to a pregnant woman’s pulse, which in Chinese medicine is known as the slippery pulse, which is a pulse that seems to slide back and forth like a rolling ball under the finger, coming and going rapidly. During pregnancy, the Qi and blood in a woman’s body will change according to the pregnancy, resulting in a slippery pulse. Although pulse diagnosis can be used to initially determine whether a woman is pregnant, Chinese medicine emphasizes the use of the four methods of observation, diagnosis and examination, and it is not possible to determine whether a woman is pregnant based on the pulse alone. In addition, pulse diagnosis has certain accuracy issues, firstly, it is related to the practitioner’s experience in the practice of medicine, as the pulse is assessed by the practitioner through the touch of the fingers, so often only experienced veteran Chinese medicine practitioners can have a more accurate determination. Secondly, as the pulse of the happy pulse, the slippery pulse can represent other diseases in addition to determining that a woman is pregnant. If the patient has symptoms such as accumulation of food in the intestines and stomach, coughing and phlegm, it may also affect the changes of Qi and blood in the body and show signs of slippery pulse. To avoid misdiagnosis, other more accurate tests should also be chosen. Clinically, pregnancy can usually be determined by using early pregnancy test strips or radioimmunoassay to test for HCG levels in a woman’s blood. Intrauterine pregnancy can usually be determined by ultrasonography at 35 days of menopause. A woman’s gestation period can be calculated from the first day of her last menstrual period, and if she is pregnant, the health of the fetus can be ensured by regular follow-up examinations, etc.
