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 ...
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 ...
The drop in blood pressure may be sudden (vasovagal orthostatic hypotension), within 3 minutes (classic orthostatic hypotension) or gradual (delayed orthostatic hypotension). [4] It is defined as a fall in systolic blood pressure of at least 20 mmHg or diastolic blood pressure of at least 10 mmHg after 3 minutes of standing.
Dysautonomia, autonomic failure, or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This may affect the functioning of the heart, bladder, intestines, sweat glands, pupils, and blood vessels. Dysautonomia has many causes, not all of which may be classified as neuropathic. [5]
Pure autonomic failure (PAF) is an uncommon, sporadic neurodegenerative condition marked by a steadily declining autonomic regulation. [3] Bradbury and Eggleston originally described pure autonomic failure in 1925. [4] Patients usually present with orthostatic hypotension or syncope in midlife or later.
Midodrine, sold under the brand names ProAmatine and Orvaten among others, is a vasopressor or antihypotensive medication used to treat orthostatic hypotension (low blood pressure when standing) and urinary incontinence. [3][5][1] It is taken by mouth. [3][1] Side effects of midodrine include hypertension (high blood pressure), paresthesia ...
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 ...
Orthostatic intolerance (OI) is the development of symptoms when standing upright that are relieved when reclining. [1] There are many types of orthostatic intolerance. OI can be a subcategory of dysautonomia, a disorder of the autonomic nervous system [2] occurring when an individual stands up. [3] Some animal species with orthostatic ...
