1) Many patients with orthostatic intolerance do not meet the require heart rate increase of POTS criteria. This new expert consensus paper argues that that this group deserves more recognition, including a separate diagnosis and ICD-code.

3) Dys-autonomia suggests there is a known, measurable defect in the autonomous nervous system - something we don't fully know yet. POTS was originally coined for patients with orthostatic intolerance but few signs of clear autonomic dysfunction.

4) IMHO the core problem is what to do with patients who have orthostatic intolerance symptoms and disability without a known cause and without clear signs of dysautonomia. The distinction between those with and without orthostatic tachycardia (POTS or not) may be less important

5) You can see this in the consensus statement which argue that both groups may have similar impairments, symptoms and that the same treatments may be useful for both. Orthostatic tachycardia is a useful clinical feature but perhaps not sufficient to base a syndrome on.
