Excessive Postural Tachycardia and Postural Orthostatic Tachycardia Syndrome in Youth: Associations With Distress, Impairment, Health Behaviors, and Medication Recommendations.

Among adolescents with fatigue and postural dizziness, it is unclear how health behaviors and emotional distress relate to the presence of excessive postural tachycardia.

Patients underwent standard 10-minute, 70-degree head-up tilt testing.
