      Fetal Electrophysiologic Abnormalities in High-Risk Pregnancies Associated With Fetal Demise
      Recruiting
                          Wisconsin
        Do you have a high-risk pregnancy? 
                    This study will investigate the use of a non-invasive scan called fetal magnetocardiography to detect potential problems in the fetus in five high-risk pregnancy conditions associated with stillbirth. The scan is normally used to look at fetal heart rhythms. To participate in this study, you must be at least 18 years old and pregnant with one of the following: having a stillbirth in a previous pregnancy, carrying identical twins, or having a fetus that has been diagnosed with major congenital heart disease, fetal hydrops, or fetal gastroschisis. This study takes place in Madison and Milwaukee, Wisconsin.

                          Indiana
        Are you a woman who is postmenopausal or a man older than 65? This study will investigate the effects of oral progesterone for older women and testosterone for older men on QT intervals. QT intervals that are increased by medicine can lead to  dangerous heart rhythm problems. Researchers hope to learn more about why this happens and how to deliver safer doses. This study is located in Indianapolis, Indiana.
