Atrial fibrillation occurs in 10% to 25% of patients with<unk> , nevertheless only 1% of patients with new onset atrial fibrillation detected to have<unk> . Elevation of thyroid hormones in<unk>  is responsible for chronotropic and dromotropic effects on heart. Mechanisms such as increase in left ventricular mass in addition to impaired ventricular relaxation which lead to elevation of left atrial pressure , Heart rate elevation and subsequent ischemia and atrial ectopic activity are proposed as possible explaination for increased risk of atrial fibrillation in hyperthyroid patients. Atrial fibrillation in the setting of thyrotoxicosis has been shown to be associated with decompensated heart failure and a significant increase in morbidity and mortality rate. Up to two-thirds of patients will reach sinus rhythm with appropriate treatment and control of<unk> .
