Heart rate responses during exercise by dominant ventricle in pediatric and young adult patients with a Fontan circulation

ConclusionsFontan patients commonly have chronotropic incompetence, diminished heart rate reserve but with preserved heart rate recovery. While there is overall no difference in chronotropy in Fontan patients based on dominant systemic ventricle, there is a difference between HLHS and tricuspid atresia patients.
