title: V. Exercise studies in children with congenital heart disease. An earpiece densitometric investigation.
abstract: Twenty-three patients have been studied by exercise testing during right heart catheterization. Cardiac output was measured by the earpiece densitometric technique before, during and after the exercise period. It is concluded that the earpiece densitometric technique in conjunction with exercise testing offers an attractive alternative for the study of pressure and flow characteristics in children with congenital heart disease.
