Key result
The tilt-table test and Valsalva maneuver are standardized methods for evaluating adrenergic autonomic function and are essential for the diagnosis of orthostatic hypotension and postural tachycardia syndrome.
The tilt-table test and Valsalva maneuver are essential standardized methods for evaluating adrenergic autonomic function in patients with orthostatic dizziness.
May support tilt-table and Valsalva use in orthostatic dizziness evaluation; leaves open prospective validation of protocols.
Orthostatic dizziness is a common dizziness syndrome characterized by nonvertiginous lightheadedness when patients rise to stand from a sitting or supine position. Orthostatic dizziness is commonly believed to derive from orthostatic hypotension (OH) or postural tachycardia syndrome (POTS). Tilt-table test and Valsalva maneuver are standardized methods for evaluating of adrenergic autonomic function and essential for diagnosis of OH and POTS. We described the guidelines and interpretations of the tilt-table test and Valsalva maneuver.

Lee et al. (2018) conducted a review in Orthostatic dizziness, Orthostatic hypotension, Postural tachycardia syndrome. Tilt-table test and Valsalva maneuver was evaluated. The tilt-table test and Valsalva maneuver are standardized methods for evaluating adrenergic autonomic function and are essential for the diagnosis of orthostatic hypotension and postural tachycardia syndrome.
