Abstract
Atrial fibrillation is the most common heart rhythm disorder in patients with chronic heart failure. One of the most effective antiarrhythmic drugs for the treatment and prevention of a wide range of supraventricular and ventricular tachyarrhythmia is amiodarone. In the group of patients with paroxysmal atrial fibrillation and low left ventricular ejection fraction, it is the drug of choice when conducting a „rhythm control“ strategy. Patients receiving amiodarone often develop an adverse event – amiodarone-induced thyrotoxicosis, which exacerbates the course of cardiovascular pathology. In this article, we consider a clinical case of amiodarone-induced thyrotoxicosis in a 30-year-old patient with dilated cardiomyopathy and agranulocytosis that developed against the background of thyrostatic therapy.
