Adrenal pheochromocytoma as a rare cause of reversible left ventricular systolic dysfunction and malignant arrhythmias: a case series.

ABSTRACT:

Background

Pheochromocytoma is a neuroendocrine tumour originating from the chromaffin cells of adrenal glands or sympathetic paraganglia. It produces most frequently norepinephrine, epinephrine, and dopamine. As a result of non-specific and variable clinical presentation, pheochromocytoma is difficult to diagnose.
