  2. Orthostatic hypotension - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_hypotension

    Orthostatic hypotension can be confirmed by measuring a person's blood pressure after lying flat for 5 minutes, then 1 minute after standing, and 3 minutes after standing. [28] Orthostatic hypotension is defined as a fall in systolic blood pressure of at least 20 mmHg or the diastolic blood pressure of at least 10 mmHg between the supine ...

  3. Orthostatic syncope - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_syncope

    Orthostatic syncope. Orthostatic syncope refers to syncope resulting from a postural decrease in blood pressure, termed orthostatic hypotension. [1] Orthostatic hypotension occurs when there is a persistent reduction in blood pressure of at least 20mmHg systolic or 10mmHg diastolic within 3 minutes of standing or being upright to 60 degrees on ...

  4. Orthostatic intolerance - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_intolerance

    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 ...

  5. Pure autonomic failure - Wikipedia

    en.wikipedia.org/wiki/Pure_autonomic_failure

    Within three minutes of standing up straight, orthostatic hypotension is defined as a drop in systolic blood pressure of at least 20 mm Hg or a drop in diastolic blood pressure of 10 mm Hg. [7] About half of PAF patients also have concurrent supine hypertension, even though all PAF patients by definition have orthostatic hypotension. [8]

  7. Syncope (medicine) - Wikipedia

    en.wikipedia.org/wiki/Syncope_(medicine)

    Hyperadrenergic orthostatic hypotension refers to an orthostatic drop in blood pressure despite high levels of sympathetic adrenergic response. This occurs when a person with normal physiology is unable to compensate for >20% loss in intravascular volume. [26] This may be due to blood loss, dehydration or third-spacing. On standing the person ...

  8. Orthostatic vital signs - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_vital_signs

    Orthostatic vital signs are also taken after surgery. [7] A patient is considered to have orthostatic hypotension when the systolic blood pressure falls by more than 20 mm Hg, the diastolic blood pressure falls by more than 10 mm Hg, or the pulse rises by more than 20 beats per minute within 3 minutes of standing [5] [7]

  9. Cerebrospinal fluid leak - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid_leak

    The most common symptom of a spinal CSF leak is a fast-onset, extremely painful orthostatic headache. [23] [25] This headache is usually made worse by standing and typically becomes prominent throughout the day, with the pain becoming less severe when lying down. [26] Orthostatic headaches can become chronic and disabling to the point of ...
