Pseudohypertension, also known as pseudohypertension in the elderly, noncompressibility artery syndrome, and Osler's sign (or Osler sign) of pseudohypertension is a falsely elevated blood pressure reading obtained through sphygmomanometry due to calcification of blood vessels which cannot be compressed.

Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
Variation in blood pressure that is significantly greater than the norm is known as labile hypertension and is associated with increased risk of cardiovascular disease [63] brain small vessel disease, [64] and dementia [65] independent of the average blood pressure level.
In contrast there is no evidence that blood pressure needs to be lowered rapidly in hypertensive urgencies, where there is no evidence of target organ damage; over-aggressive reduction of blood pressure is not without risks. [3] Use of oral medications to lower the BP gradually over 24 to 48h is advocated in hypertensive urgencies. [4]
Significant variations in blood pressure could be an indication that a person is at risk of a heart attack or stroke, a study has suggested. Researchers warned there is an urgent need for “new ...
Initial orthostatic hypotension is frequently characterized by a systolic blood pressure decrease of ≥40 mmHg or diastolic blood pressure decrease of ≥20 mmHg within 15 seconds of standing. [32] Blood pressure then spontaneously and rapidly returns to normal, so the period of hypotension and symptoms is short (<30 s). [32]
Reviewed by Dietitian Annie Nguyen, M.A., RD. Your heart is arguably the hardest-working muscle in your body. Every day it pumps nearly 2,000 gallons of blood through your arteries to supply the ...
Blood pressure is measured in units called millimeters of mercury, or mm Hg. Normal blood pressure is typically below 120/80 mm Hg. High blood pressure, or hypertension, is defined as anything ...
