Multiple causes.: Anemia, infection, hyperthyroidism, heart failure, valvular heart disease, autonomic dysfunction, pericarditis, myocarditis. Rare causes would include neuroendocrine tumors such as a pheochromocytoma. It merits a careful history and physical exam, ecg, chest x-rays and some routine blood tests.
