- •
We found significant differences in hemodynamic profile of hyperadrenergic versus non-hyperadrenergic postural orthostatic tachycardia syndrome (POTS).
- •
Based on these differences we developed criteria which, when implemented in our cohort, detected non-hyperadrenergic POTS with 76% sensitivity and 80% specificity.
- •
Results of HRV analysis indicate that hyperadrenergic POTS patients’ have diminished vagal tone even at rest.
