From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

These symptoms are part of metabolic and ion transportation symptoms recognized in the International Consensus Criteria and are optional diagnostic criteria for Myalgic Encephalomyelitis.

Cardiovascular e.g. inability to tolerate an upright position - orthostatic intolerance (OI), neurally mediated hypotension (NMH), postural orthostatic tachycardia syndrome (POTS), heart palpitations with or without cardiac arrhythmias, light-headedness/dizziness.[1]

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).

See postural orthostatic tachycardia syndrome.

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).
