Fetal Arrhythmias

Abstract

Pathological heart rhythm disturbances in the fetus are uncommon, however, being able to correctly diagnose the type of arrhythmia and instigate the appropriate treatment is crucial for a good fetal outcome. In contrast to postnatal life, the diagnosis is usually made using ultrasound rather than electrocardiographic techniques. Tachycardias, bradycardias and irregular fetal heart rhythms are discussed including the approach to diagnosis and management.
