Thirty-four patients were studied by electrocardiogram for electrical position of the heart, and by x-ray and angiocardiogram for anatomic position of the heart. A significant association between electrocardiographic and anatomic positions of the heart was found insofar as rotation about the anteroposterior and longitudinal axes is concerned. No association between electrocardiographic and anatomic positions was found with regard to rotation about the transverse axis.
