Abstract

Intracardiac infusion of acetylcholine into the right atrium or right ventricle during steady-state exercise in 20 patients with rheumatic heart disease resulted in only minimal alterations in the pressure in the pulmonary artery. The vasodilator effect of acetylcholine on the pulmonary artery under these conditions is minimal and of little or no clinical significance.
