Low‐frequency power of heart rate variability is not a measure of cardiac sympathetic tone but may be a measure of modulation of cardiac autonomic outflows by baroreflexes
Power spectral analysis of heart rate variability has often been used to assess cardiac autonomic function; however, the relationship of low‐frequency (LF) power of heart rate variability to cardiacExpand

Sources and Significance of Plasma Levels of Catechols and Their Metabolites in Humans
Human plasma contains several catechols, including the catecholamines norepinephrine, epinephrine, and dopamine, their precursor, l-3,4-dihydroxyphenylalanine (l-DOPA), and their deaminatedExpand

Biochemical diagnosis of pheochromocytoma: which test is best?
CONTEXT Diagnosis of pheochromocytoma depends on biochemical evidence of catecholamine production by the tumor. However, the best test to establish the diagnosis has not been determined. OBJECTIVEExpand

Stress-Induced Norepinephrine Release in the Hypothalamic Paraventricular Nucleus and Pituitary-Adrenocortical and Sympathoadrenal Activity: In Vivo Microdialysis Studies
The hypothalamic-pituitary-adrenocortical (HPA) axis and the autonomic nervous system are major effector systems that serve to maintain homeostasis during exposure to stressors. In the past decade,Expand

Malignant pheochromocytoma: current status and initiatives for future progress.
Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors that are usually benign, but which may also present as or develop into a malignancy. Predicting such behavior is notoriouslyExpand
