ELECTROCARDIOGRAPHIC CHANGES IN CHRONIC COR PULMONALE

Abstract

Electrocardiographic abnormalities have long been noted in cases of heart failure due to chronic cor pulmonale but there has been much discussion about their diagnostic importance and their causation. This paper is a study of a small series of cases of well established chronic cor pulmonale with congestive heart failure, in an attempt to determine the typical cardiographic pattern and to distinguish, if possible, changes due to abnormality of the heart from changes due to its altered position in the thorax.
