white coat effect 白大褂效应

White coat effect refers to the elevation of a patient's blood pressure readings caused by being in a doctor's office or clinic, or by being in the presence of a physician.

“白大褂效应”指病人在医生办公室、诊室或者有医务人员在场时量血压，血压都会升高的现象。

Racing pulses at the doctor's office are so common, there's even a name for it -- "white coat hypertension." Unfortunately, that spike in blood pressure can make it difficult for doctors to tell how patients are really doing.

在医生办公室时脉搏就会加速是很常见的现象，这种现象被称为“白大褂高血压”。由此带来的不利影响是，这种血压突然上升的状况让医生很难判断病人的真实病情。
