Provocation of Neurocardiogenic Syncope During Head-up Tilt Testing in Children: Comparison Between Isoproterenol and Nitroglycerin

Abstract: Nitroglycerin- and isoproterenol-augmented tilt tests are associated with equal sensitivity in the diagnosis of neurocardiogenic syncope in children and adolescents. However, nitroglycerin results in more false-positive tests and produces more prolonged vasovagal symptoms. Our data do not support the routine use of nitroglycerin in the evaluation of syncope in this age group.

“…Comparaciones entre ambos protocolos muestran que la activación con nitroglicerina o isoproterenol mejora la sensibilidad de un TT pasivo 5,15,16,[17][18][19][20][21][22] . Incluso describen una sensibilidad y especificidad muy similares para isoproterenol y nitroglicerina 5,[17][18][19][20][21][22] .…”
