Abstract:

Transient fetal arrhythmia is more common than persistent fetal arrhythmia.Persistent fetal arrhythmia is correlated with fetal hydrops，preterm delivery，and higher perinatal morbidity and mortality.Prenatal assessment with M-mode and echocardiography can enhance diagnostic accuracy.Precise prenatal diagnosis and intrauterine interventions may improve the prognosis of arrhythmic fetuses.

Key words: arrhythmia, fetal, echocardiography, prenatal diagnosis, intrauterine therapy

摘要：

胎儿一过性心律失常的发生率相对更高。持续性的心律失常通常与胎儿水肿、早产、围产儿发病率及死亡率的增加相关。产前通过M型超声或胎儿超声心动图能够增加胎儿心律失常的诊断率。精准的产前诊断及宫内干预，有望改善心律失常胎儿的预后。
