Heart Rate Variability is Related to Disease Severity in Children and Young Adults with Pulmonary Hypertension

[摘要] BackgroundPulmonary hypertension (PH) is frequently associated with an increase in sympathetic tone. This may adversely affect cardiac autonomic control. Knowledge about the clinical impact of autonomic dysfunction in patients with PH is limited. We aimed to assess whether parameters of heart rate variability (HRV) are related to disease severity in children with PH.
