Post-exercise heart rate, blood pressure and oxygen uptake dynamics in pediatric patients with Fontan circulation

In the Fontan group, post-exercise HR and V˙O2 declines are markedly delayed and are determined by cardiac vagal nervous activity, exercise capacity and age, respectively. Despite identical impaired hemodynamics and exercise capacity, post-exercise SBP decline is greater in the Fontan group, especially after APC, than in the RVOTR patients.
