<unk>  is a reversible phenomenon of  catecholamine mediated myocardial inflammation seen in pheochromocytoma.  Pheochromocytoma is a tumor of adrenal medulla which produces excess amount of catecholamines.  Wide spectrum of myocardial dysfunctions are present in pheochromocytoma which include acute myocardial infarction (both ST elevation and non ST elevation), cardiomyopathy, takotsubo cardiomyopathy, congestive heart failure, acute pulmonary edema and cardiac arrythmia.  Direct myocardial injury caused by catecholamines is the most popular theory among other suggested causes.
