The purpose of this study is to describe the mechanism of orthostatic intolerance, relying on
cardiovascular physiological studies. The syndrome is of undetermined etiology, but the
syndrome causes impairment of a number of young adults, females more than males, with
symptoms of tachycardia, fatigue, lightheadedness, palpitations, blurred vision, chest
discomfort, difficulty concentrating, and dizziness with the upright posture. It is believed
that many different pathophysiological processes can give rise to this disorder.

Inclusion Criteria:

- Orthostatic intolerance

Exclusion Criteria:

- Inability or unwillingness to give informed consent
