Abstract:
Serious predominantly diastolic treatment-resistant hypertension with unstable blood pressure values draws first contact physician's attention to a possibility of pheochromocytoma, although in some periods of disease blood pressure values of a patient can be normal or only slightly elevated. Clinical picture is sometimes atypical, can be overlooked or lead to a wrong diagnosis. The author brings forward atypical cases where pheochromocytoma emulates different disease or diseases with clinical pictures similar to that of pheochromocytoma.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
