[Note: propranolol is a ‘beta blocker’ mainly used in treatment of high blood pressure. It blocks epinephrine (adrenalin), the sympathetic nervous system’s “fight or flight” stress-reaction hormone. Orthostatic intolerance is an inappropriate heart rate and blood pressure response to a change in body position from prone to upright.]

We describe the effect of propranolol in an adolescent with Chronic Fatigue Syndrome and orthostatic intolerance.
Our observations suggest that the head-up tilt-test and beta-blocker treatment might be considered in patients with Chronic Fatigue Syndrome and that enhanced sympathetic nervous activity might be part of the underlying pathophysiology.
