Qualitative Sweat Distribution During Tilt Table Procedure
Completed · Not applicable
Conditions studied: Postural Tachycardia Syndrome, Syncope, Anxiety
In brief
This study uses an Alizarin Red powder mixture to characterize the sweat distributions in youth during tilt table testing. Patients with a known orthostatic sweat response from a prior clinical tilt table test in the investigators laboratory will be recruited. The Alizarin Red powder will be applied to exposed skin, and quantitative sweat will be measured at the thigh. During tilt testing, serial photos will be taken once the sweat response occurs. Sweat distributions will be compared during syncope (orthostatic sweat), during periods of anxiety (emotional sweat), and in patients with POTS (with and without syncope).
