Abstract
Objective:
To determine postnatal electrocardiographic abnormalities in fetuses with echogenic cardiac foci （ECF） and no congenital heart disease （CHD）。
Study Design:
A total of 41 fetuses with ECF and no CHD, were prospectively followed after birth with serial echocardiograms, electrocardiogram （ECG） and 24-h ECG （Holter）。 The primary outcome was presence of significant abnormalities in the ECG or Holter.
Result:
ECF diagnosed at a mean （s.d.） of 25.6 （4.6） weeks gestation, were located in the ventricles and in the atria in 39 （95.1%）， and 2 fetuses （4.9%）， respectively. Postnatal follow-up was for 8.1 （4.6） months （range 1 to 24）。 None of the infants had any clinically significant abnormality in the ECG or Holter. ECF resolved in 10 infants （24.3%） by 24 months of age. There was no difference between infants with resolved or persistent ECF in various ECG or Holter measurements compared.
Conclusion:
Fetuses with ECF and no CHD have no significant postnatal electrocardiographic abnormalities, irrespective of ECF persistence or resolution.
