==Overview==
Common physical exam findings of pheochromocytoma include [[tachycardia]], [[hypertension]], and [[orthostatic hypotension]].
Patients with [[pheochromocytoma]] usually appear [[diaphoretic]] and [[anxious]]. Physical examination of patients with [[pheochromocytoma]] is usually remarkable for  [[tachycardia]], [[hypertension]], and [[orthostatic hypotension]].

==Physical Examination==
Common physical exam findings include:
Physical examination of patients with [[pheochromocytoma]] is usually remarkable for  [[tachycardia]], [[hypertension]], and [[orthostatic hypotension]].
*[[Tachycardia]]
 
*[[Hypertension]], including paroxysmal (sporadic, episodic) high blood pressure, which sometimes can be more difficult to detect.
=== Appearance of the Patient ===
*[[Orthostatic hypotension]]

Overview

Patients with pheochromocytoma usually appear diaphoretic and anxious. Physical examination of patients with pheochromocytoma is usually remarkable for tachycardia, hypertension, and orthostatic hypotension.
