The Auricles in Cases of Auricular Fibrillation

Although a remarkable advance has been made in recent years in the knowledge of the irregularities of cardiac rhythm and of abnormal cardiac rates and very definite ideas have been established in regard to the mechanisms that underly these abnormalities, very little has been added to the knowledge of the condition of the walls of the heart, especially of the auricles, which might be a factor in producing some of these disturbances in rate and rhythm. Many of these abnormalities in cardiac rate and rhythm are associated with disturbance in the normal action of the auricles, and still in most pathologic reports on the heart there is very little information given in regard to the condition of the auricular walls as compared with those of the ventricles. It is hoped that in the future pathologists will include in their routine description of the heart some information in regard to the
