[1] The murmur results from the rubbing of the pericardium against the pleura in the context of hyperdynamic circulation and tachycardia, [2] and may mimic the sound of a pericardial rub. [3]

When hyperthyroidism is treated these decrease and an increase of serum creatinine often occurs, which may cause azotaemia and in some cases renal ...
