INVERSION OF THE T WAVES IN LEAD II CAUSED BY A VARIATION IN POSITION OF THE HEART

Abstract

Only in late years has there begun to be adequate recognition of the wide variations of the normal human electrocardiogram. As has so often happened in medical science, diseased conditions and abnormal findings have attracted so much attention that a patient study of the normal subject and his physio- logical variations has been left far behind. This is particularly true in clinical electrocardiography where we still depend for our normal criteria on a relatively small number of records.
