Neurally mediated hypotension

Neurally mediated hypotension as explained by Blood Pressure Updates "is a complication that occurs due to unnatural reflex action between the brain and heart, though they are structurally normal. Neurally mediated hypotension is also called fainting reflex, or vasodepressor syncope or neurocardiogenic syncope or autonomic dysfunction or vaso-vagal reflex. Syncope is the formal medical term used for fainting."

orthostatic intolerance (OI) - The development of symptoms when standing upright, where symptoms are relieved upon reclining. Patients with orthostatic intolerance have trouble remaining upright for more than a few seconds or a few minutes, depending upon severity. In severe orthostatic intolerance, patients may not be able to sit upright in bed. Orthostatic intolerance is often a sign of dysautonomia. There are different types of orthostatic intolerance, including postural orthostatic tachycardia syndrome (POTS).

postural orthostatic tachycardia syndrome (POTS) - A form of orthostatic intolerance where the cardinal symptom is excessive tachycardia due to changing position (e.g. from lying down to sitting up).
