Determinants of development and preservation of atrial fibrillation at thyrotoxicosis

Cover Page


Atrial fibrillation is a frequent violation of a heart rhythm at thyrotoxicosis and it can determine serious complica tions (tromboembolia, stroke) and death. The study of factors increasing risk development of atrial fibrillation at thy rotoxicosis is investigating many years but the occurrence of new diagnostic methods and mathematic analysis allows to reveal new determinants of development of atrial fibrillation and its persistence after restoration of euthyreosis. In our research we’ve studied the Echocardiography parameters in 254 normotensive patients with a thyrotoxicosis Graves’ disease without any CVD and 110 patients with a subclinical thyrotoxicosis. We detected new factors of risk of atrial fibrillation: the duration of thyrotoxicosis and the left ventricular concentric hypertrophy. The contribution of different factors in development of atrial fibrillation is defined.
