摘要
•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.
