Background
- More common in older patients
- Symptomatic orthostasis more important than actual change in vitals
- Classically drop in SBP ≥20 mm Hg or increase in HR ≥ 30 bpm when moving from lying to standing
Clinical Features
- Sudden postural changes resulting in cerebral hypoperfusion
- Weakness, lightheadedness, visual blurring
- Occasionally syncope
Differential Diagnosis
- Autonomic dysfunction
- Volume depletion
- Diuretics
- Hemorrhage
- Vomiting/ Diarrhea
- Medications
- Antihypertensives, antiparkinsonism, beta blockers, vasodilatory drugs
- Alcohol use
- Aging
- Syncope
- Seizure
Evaluation
- Review medication list
- History of potential volume loss
- CBC (anemia)
- BMP (electrolytes, BUN, Cr, glucose)
- EKG
Management
- Address the underlying cause
- Fluids, blood transfusion when appropriate
- Consider discontinuing at risk medications
Disposition
Depends on patient's risk, etiology of orthostasis disposition, secondary complications
