ERRATUM

The following error was made in the article, "Some Effects of Digoxin upon the Heart and Circulation in Man: Digoxin in Cor Pulmonale," by Ferrer, Harvey, Cathcart, Webster, Richards, and Cournand, in the February issue of the Journal (Circulation 1: 161, 1950). In figure 7 (page 182), the arrow indicates that pulmonary hypertension leads to increased cardiac output. The reverse is, of course, the case; the arrow should have indicated that increased cardiac output leads to pulmonary hypertension.
