滑数脉是中医古籍中反映妊娠的主要特征脉象，但由于“滑数”是一种主观感受而使外界对孕脉的科学性和实用性产生质疑。笔者通过回溯中西医对孕妇生理的认识，并结合自身在内分泌科和急诊科的专业经验，认为孕脉脉象并不神秘，也不难掌握。孕脉的形成与孕早期人绒毛膜促性腺素（HCG）升高引发甲状腺功能生理性适度升高密切相关，加之孕期人体的整体和谐联动，使孕期心输出量和脉搏弹性增加，故孕脉与年轻亚临床甲状腺功能亢进症（以下简称“亚临床甲亢”）患者的脉象有所相似。笔者建议，在理解和掌握滑数脉时，除了通过对孕妇进行脉诊以获取直观感受之外，还可以对年轻亚临床甲亢患者进行脉诊，以体会和感受类似于孕脉的脉象特征。孕脉与亚临床甲亢脉象的相似性提示临床医生，对于甲状腺功能检查提示亚临床甲亢，或出现亚临床甲亢脉象且促甲状腺激素受体抗体（TRAb）未升高的孕龄女性，均应重视排查早孕，以免误治对孕妇造成伤害。

The slippery and rapid pulse is the main pulse condition recorded in ancient traditional Chinese medicine texts as indicative of pregnancy. However,because the description of “slippery and rapid” is based on subjective perception,the scientific validity and practicality of the pregnancy pulse have been questioned by the outside world. The authors,by tracing back the understanding of pregnant women's physiology in traditional Chinese and Western medicine and combining it with professional experience in the endocrinology department and the emergency department,believes that the pulse characteristics of pregnant women are neither mysterious nor difficult to master. The formation of the pregnancy pulse is closely related to the physiological and moderate increase in thyroid function triggered by the elevation of human chorionic gonadotropin(HCG) in the early stage of pregnancy. Coupled with the overall harmonious interaction of the human body during pregnancy,the cardiac output and pulse elasticity increase during pregnancy. Therefore,the pregnancy pulse is somewhat similar to the pulse of young patients with subclinical hyperthyroidism. The authors suggest that when understanding and mastering the slippery and rapid pulse,in addition to directly performing pulse diagnosis on pregnant women to obtain an intuitive feeling,one can also perform pulse diagnosis on young patients with subclinical hyperthyroidism to experience and feel the pulse characteristics similar to those of pregnant women. The similarity between the pregnancy pulse and the pulse of subclinical hyperthyroidism reminds clinicians that for women of childbearing age whose thyroid function tests suggest subclinical hyperthyroidism,or who present with a pulse resembling that of subclinical hyperthyroidism,and whose thyroid stimulating hormone receptor antibody(TRAb) levels have not increased,it is important to conduct early pregnancy screening in order to avoid harm caused by misdiagnosis and inappropriate treatment.
