Abstract
Hemodynamic studies were made in 42 patients with rheumatic heart disease with various valvular lesions and in different stages of cardiac function. These studies include observations not only at rest, but also during exercise, following the acute administration of Digoxin, and after recovery from failure. The relationship between symptomatology and hemodynamic findings were considered and the importance of differentiating between mechanical block and left ventricular myocardial failure as causes for pulmonary artery hypertension is stressed.
