tachyarrhythmia with an associated mortality rate of 10%. Adequate
diagnosis, awareness of association including fetal hydrops and cardiac
anomaly, and multidisciplinary team involvement often ensure optimal
outcome. Postnatal cardioversion a successful way of achieving sinus
rhythm and antiarrhythmic prophylaxis is often necessary especially for
the neonatal period. It is essential fetal AF is not managed as ‘fetal
distress’ by general obstetricians and midwives. Call for help when in
doubt.
