Objective: The paper presents review of different kinds of fetal arrhythmias, diagnosed in our centres.
Design: The aim of our study was to analyse results of echocardiographic examinations of 141 fetuses with diagnosed arrhythmias referred for fetal cardiac examination in years VI. 1996-V. 2001 and neonatal outcome.
Results: Premature contractions were recognised in 113 (80%) fetuses, tachyarrhythmias in 7 (5%) cases and complete atrioventricular block in 5 (4%). Heart defects were diagnosed in three cases. Three fetuses developed congestive heart failure (2x SVT, 1x HLHS + block a-v III*). From all group 6 newborns died.
Conclusion: In case of fetal arrhythmias echocardiography should be widely applied in order to evaluate the kind of arrhythmia, sufficiency of circulation and coexistence of heart defects or functional abnormalities with arrhythmia in fetal circulation.
