Pseudohypertension
Pseudohypertension
Pseudohypertension (/ˌsjuːdoʊ.haɪ.pɚˈtɛnʃən/), also known as Osler's sign, is a medical condition where the blood pressure appears to be elevated when measured by a sphygmomanometer, but is actually normal when measured directly. This condition is most commonly seen in elderly patients with stiff, calcified arteries.
Etymology
The term "Pseudohypertension" is derived from the Greek word "pseudo-", meaning false, and the Latin word "hypertensio", meaning high tension or pressure. The term was first used in medical literature in the 20th century.
