胎儿心律失常是一种常见胎儿心脏疾病，主要包括期前收缩、心动过速和心动过缓。大多数情况下的胎儿心律失常属于良性病变，在少数情况下，严重的心律失常如室上性心动过速、心房扑动和房室传导阻滞等会导致胎儿心功能不全、胎儿水肿甚至胎儿宫内死亡的发生，因此及时的宫内治疗干预将有助于改善胎儿预后。本文就不同类型胎儿心律失常的宫内治疗进行总结。“,”Fetal arrythmia is a common cardiac abnormality, which can be categorized into three major types: extrasystoles, tachycardia and bradycardia. Most fetal arrythmias do no harm to the fetus, but few severe fetal arrythmia, including supraventricular tachycardia, atrial flutter and conduction block do, resulting in congestive heart dysfunction, hydrops fetalis and even intrauterine death. Therefore, timely intrauterine management may help to improve the fetal outcomes. This article reviews intrauterine treatment strategies for different types of fetal arrythmia.
