The electrocardiogram in complete transposition of the great vessels.

Most authors correlated the electrocardiogram with the underlying pathology of the ventricular septum and the presence or absence of pulmonary stenosis, while Elliott et al. (1963a) correlated their findings with the size of the associated defects at necropsy. Little attempt, however, has been made to correlate the electrocardiogram with the hemodynamics of the circulation and the pathology of the heart. This study aims to make this correlation and is con- fined to complete transposition of the great vessels with normal position of the atria and of the ven- tricles, as defined in the classification suggested by Shaher and Johnson (1963), and Shaher (1964a). Patients with associated single ventricle or with tri- cuspid atresia have been excluded.
