Early intra-auricular electrocardiographic recordings support the dipole concept of cardiac excitation and have direct clinical utility.
The technic of endocardial electrocardiography has been useful in applying certain basic concepts to the interpretation of an electrocardiogram. One of the earliest intra-auricular records, obtained in 1944, is here analyzed in detail. It led to a reaffirmation of the dipole concept of cardiac excitation. A number of selected auricular electrocardiograms recorded by simultaneous tracings from the chestwall and the esophagus demonstrate the direct clinical usefulness of the theoretic postulates.
Hecht et al. (1950) studied this question.
