Right Ventricular Myocardial Infarction. The triad of jugular vein distention, clear lung fields, and hypotension is the classic picture of right ventricular dysfunction. Epub Oct The clinical signs of this are increased right sided heart pressures, increased pulmonary artery PA systolic pressures, and decreased left ventricular preload. Findings of an enlarged heart silhouette, dilation of the inferior or superior venae cavae, and clear lung fields may be present. National Center for Biotechnology Information , U.
