[Nature of the heart rhythm, size of the left atrium and cardiac volume in aortic stenosis].
Examination of 32 patients with aortic stenosis permitted the author to establish quantitative relationships between the dimensions of the left atrium and the continuous form of atrial fibrillation, between the dimensions of the left atrium, the heart volume and paroxysmal atrial fibrillation. Atrial fibrillation develops in aortic stenosis in the terminal stage of the disease. Quantitative relationships between the dimensions of the left atrium and continuous atrial fibrillation are similar to those in mitral incomperence which is evidence by the similarity of hemodynamic disorders in the left atrium in mitralism during aortic stenosis and mitral insufficiency.
