摘要：

We previously assessed right ventricular (RV) diastolic filling in normal neonates, infants, children and adolescents.1-3 In those studies, we found significant respiratory variation in RV filling. We hypothesized that inspiration would increase the RV stroke volume and thereby increase the valvar pressure gradient in patients with congenital valvar pulmonic stenosis. © 1992.
