Autonomic dysfunction (orthostatic hypotension, POTS)
Autonomic dysfunction is impaired autonomic regulation of blood pressure and/or heart rate. Includes orthostatic hypotension (OH — BP drops on standing → dizziness/syncope), POTS (excessive HR rise on standing with orthostatic symptoms), and autonomic failure (neurogenic OH in Parkinson's, MSA, diabetes, etc.). Dental relevance: rapid position changes, anxiety, dehydration, and vasodilating medications can trigger presyncope/syncope in the dental chair. Supine hypertension is a paradoxical risk in neurogenic OH patients lying flat.
