      Fetal Electrophysiologic Abnormalities in High-Risk Pregnancies Associated With Fetal Demise
      Recruiting
                          Wisconsin
        Does your developing baby have a heart defect? Have you had a stillborn baby?
                    This study tests a new technology to measure fetal heart activity and find possible problems early. These problems include fetal arrhythmia and conduction disorders such as Brugada syndrome. To participate in this study, you must be at least 18 years old and pregnant, and have one of five high-risk complications of pregnancy: a fetus with a major congenital heart defect, hydrops, or gastroschisis; a previous unexplained stillbirth; or twins who share a placenta. This study is located in Madison and Milwaukee, Wisconsin.

    Pathophysiology of Orthostatic Intolerance
      Recruiting
                          Tennessee
        Have you been diagnosed with orthostatic intolerance?
                    This study aims to find out how the body’s regulation of basic functions, such as heart rate and blood pressure, is altered in people who have orthostatic intolerance. This condition, which has an unknown cause, is characterized by a racing heartbeat, dizziness, lightheadedness, and other symptoms that occur when a person stands up. To participate in this study, you must be between 18 and 80 years old and have orthostatic intolerance. This study is located in Nashville, Tennessee.
