The electrocardiographic pentalogy of pulmonary emphysema. A correlation of roentgenographic findings and pulmonary function studies.

The clinical applicability of the routine electrocardiogram and the chest roentgenogram in assessing advanced pulmonary emphysema is shown by a correlative study on 150 adults with moderately severe and severe pulmonary emphysema determined by pulmonary function studies. From these data a rather uniform electrocardiographic pattern has emerged entitled "the electrocardiographic pentalogy of pulmonary emphysema" which by itself suggests the presence of an advanced emphysematous state.
