Orthostatic hypertension. Orthostatic hypertension is a medical condition consisting of a sudden and abrupt increase in blood pressure (BP) when a person stands up. [1] Orthostatic hypertension is diagnosed by a rise in systolic BP of 20 mmHg or more when standing. Orthostatic diastolic hypertension is a condition in which the diastolic BP ...
Definition. Orthostatic hypotension (or postural hypotension) is a drop in blood pressure upon standing. One definition (AAFP) calls for a systolic blood pressure decrease of at least 20 mm Hg or a diastolic blood pressure decrease of at least 10 mm Hg within 3 minutes of standing. [30]
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
Postural orthostatic tachycardia syndrome (POTS) is a disorder of the autonomic nervous system, which controls body functions we often don’t think about, such as heart rate and blood pressure.
Orthostatic vital signs are a series of vital signs of a patient taken while the patient is supine, then again while standing. [1] The results are only meaningful if performed in the correct order (starting with supine position). [2][3][4] Used to identify orthostatic hypotension, [5] orthostatic vital signs are commonly taken in triage ...
Supine hypertension. Supine hypertension is a paradoxical elevation in blood pressure upon assuming a supine position from a standing or sitting position. [1][2][3] It is assumed to be a manifestation of disorders of the autonomic nervous system [4] or due to side effects of medications such as midodrine and droxidopa. [5][6]
t. e. Hypertension, also known as high blood pressure, is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. [11] High blood pressure usually does not cause symptoms itself. [1] It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral ...
The first-dose phenomenon is a sudden and severe fall in blood pressure that can occur when changing from a lying to a standing position the first time that an alpha blocker drug is used [1] or when resuming the drug after many months off. [2] This postural hypotension usually happens shortly after the first dose is absorbed into the blood and ...
