title: Restoration of sinus rhythm following levothyroxine treatment in a case of primary hypothyroidism presenting with atrial fibrillation and pericardial effusion.
abstract: A 72-year-old man presented with palpitation, dyspnea, and chest discomfort. Initial investigations revealed atrial fibrillation (AF) and pericardial effusion, further investigations unraveled primary hypothyroidism (thyroid stimulating hormone) of 34.7 μIU/ml and total thyroxine (T4) of 5.57 μg/dl). Treatment with levothyroxine led to resolution of symptoms, AF, and pericardial effusion.
