Foetal Tachyarrhythmias: A Modern State of the Problem

Objective of the Review: To present the modern state of the support for pregnant women with foetal tachyarrhythmias. Key Points. The antenatal diagnosis of arrhythmia, pregnancy and labour in women with this foetal pathology are discussed. The causes of arrhythmias and nonimmune foetal dropsy, characteristics of foetal myocardium, have been analysed. The need in the therapy of lifethreatening foetal tachyarrythmias has been justified. Medical assistance to this category of patients has been presented. Conclusion. Foetal tachyarrythmia is a significant cause of increased antenatal and infant mortality rates; if untreated, it leads to the death of the foetus/newborn. When started right after the diagnosis of tachyarrythmia, foetal therapy can significantly improve perinatal outcomes due to foetus stabilisation or complete antenatal recovery; it makes it possible for a woman to deliver a term baby and to minimise the treat of a poor outcome.
