Determinants of the relation between systolic pressure and duration of isovolumic relaxation in the right ventricle.

Abstract

Previous studies have suggested that right ventricular systolic pressure can be predicted from noninvasive estimates of the interval between pulmonary valve closure and tricuspid valve opening. To determine the basis for this relation, phonocardiograms and high fidelity right atrial and ventricular pressures were recorded in 29 patients with a right… (More)
