Why the study?
Is parasympathetic activity reduced and associated with exercise capacity in patients with congenital heart disease?
Is parasympathetic activity reduced and associated with exercise capacity in patients with congenital heart disease?
Patients with congenital heart disease exhibit impaired parasympathetic activity, highlighting a potential target for improving functional outcomes.
Answers are grounded in this paper and cite their sources.
Impaired parasympathetic activity may limit exercise capacity in congenital heart disease; hypothesis-generating and should not yet change practice.
Impaired parasympathetic activity suggests limited function of the ANS in patients with CHD. Further studies should focus on the association of exercise capacity and ANS to possibly improve parasympathetic activity and functional outcomes.
