Sleep Actigraphy in Postural Tachycardia Syndrome (POTS)

Assessment of Objective Sleep Disturbances in Orthostatic Intolerance Using Actigraphy

NCT00692471•Satish R. Raj

Summary

We propose to use actigraphy (measured by activity watches) as a tool to quantify sleep disturbances in patients with orthostatic intolerance compared with healthy control subjects. In this pilot study, we will test the null hypothesis (Ho) that there are no differences in the sleep quality between patients with orthostatic intolerance and healthy control subjects.
