White Coat Hypertension Meaning

(medicine, idiomatic) Elevated blood pressure measured by a medical practitioner and deemed to result from the patient's emotional response to the medical environment.

Example: 1988, T. G. Pickering et al., "How common is white coat hypertension?", Journal of the American Medical Association (JAMA), 8 Jan.,
  Patients with white coat hypertension did not show a generalized increase of blood pressure lability, nor an exaggerated pressor response while at work. . . . In such patients, the pressor response may be relatively specific to the physician's office and lead to significant misclassification of hypertension.
