We report a previously healthy 43 years old male, that one year ago presented with a hyperthyroidism, treated with metimazole and radioiodine. Two months after receiving the latter, he was admitted to the hospital for dyspnea, tachycardia and chest pain. An atrial fibrillation with a frequency of 190 beats per minute was found. During hospital stay, the patient suffered a cardiogenic shock that recovered. The patient was discharged five days after admission. During follow up, there was a progressive reduction of cardiac symptoms.
