Prospective Maternal Surveillance of SSA (Sjögren Syndrome A) Positive Pregnancies Using a Hand-held Fetal Heart Rate Monitor

The study will enroll mothers during week 16-19 of gestation and will ask the mothers to use
a hand-held Doppler monitor to listen to the baby's heart rate and rhythm twice daily from
about week 16 to week 26 of the pregnancy. Pregnant mothers will be asked to keep a log of
the heart rates and will undergo a fetal echocardiogram every 2 weeks during their study
participation. In addition to these procedures, the study team will collect the mother's
medical and obstetrical histories. Should irregular heart rhythms be detected at home, the
mother will contact the investigator to be evaluated. After the baby is delivered, the study
team will collect information about the baby's birth and heart rhythm evaluation
(electrocardiogram).
