The Long QT Syndrome in Pregnancy

Long QT Syndrome (LQTS) is a disease of young adults and can affect women of child bearing age. Suffers of LQTS are at risk of ventricular dysrhythmias including torsades de pointes and ventricular fibrillation. Pregnancy increases the chance that any mother may have an abnormal heart rhythm or arrhythmia. This chance is higher with the LQTS. There are only a few reported cases of women with the LQTS having a baby in the medical literature. This can make it difficult for the doctor caring for a pregnant woman with the long QT syndrome - especially should they need an anesthetic. We would like to study as many women who have had a baby who have the long QT syndrome to give us a better idea of whether there are any arrhythmias occurring at the time of delivery.
