title: [Prenatal diagnosis of arrhythmias and conduction disturbances].
abstract: OBJECTIVE
  Cardiac arrhythmias are one of the most frequent indications for the fetal echocardiographic assessment. The objective of this work is to present our own results of diagnosing and treating the fetuses with arrhythmias.
  
  
  METHODS
  The 1485 prenatal echocardiographic examinations were performed in 1302 fetuses. The 109 of fetuses suffered from arrhythmias.
  
  
  RESULTS
  68 fetuses (62.8%) in the analysed group presented with arrhythmias in the form of extra-systoles, 19 fetuses (17.4%) with tachycardia and 22 (20.2%) with a complete atrioventricular block.
  
  
  CONCLUSIONS
  We concluded, that arrhythmias can be diagnosed precisely in the early prenatal period, which enables the introduction of the adequate pharmacological treatment and the coexistence of the fetal complete a-v block and structural heart defect in a fetus is associated with poor prognosis.
