RESUMEN
In recent years, exercise testing has been increasingly used in pediatrics, especially in pediatric cardiovascular diseases.Its ability to monitor heart rate, blood pressure, electrocardiogram, oxygen saturation, and expiratory gas analysis is of great clinical value.In pediatric cardiovascular diseases, exercise testing can further evaluate arrhythmias, facilitate the differential diagnosis of syncope, and detect early myocardial perfusion defects in children with cardiomyopathy and Kawasaki disease; in addition, expiratory gas analysis of exercise testing can assess cardiorespiratory fitness in children and the operative results of congenital heart disease, etc.This article reviews the use of exercise testing in children with arrhythmias, cardiomyopathy, congenital heart disease, and Kawasaki disease.
