Abstract

Twelve patients with persistent fetal bradycardia were referred for echocardiographic assessment; in 10 patients the fetus had complete heart block, six isolated and four with associated structural heart disease. In the remaining two patients an atrial arrhythmia was producing a fetal sinus bradycardia. Complete heart block with structural heart disease has a poor prognosis. Isolated complete heart block has a good prognosis if the pregnancy is carefully managed. A sinus bradycardia due to atrial ectopic beats is a benign arrhythmia. Echocardiographic assessment of the heart can give an accurate prognosis in fetal bradycardia and provide a basis for appropriate obstetric management.

摘要

12例持续性胎儿心动过缓患者被转诊进行超声心动图评估；10例胎儿患有完全性心脏传导阻滞，其中6例为孤立性，4例伴有结构性心脏病。其余2例患者存在房性心律失常，导致胎儿窦性心动过缓。伴有结构性心脏病的完全性心脏传导阻滞预后较差。如果孕期管理得当，孤立性完全性心脏传导阻滞预后良好。房性早搏引起的窦性心动过缓是一种良性心律失常。对胎儿心脏进行超声心动图评估可准确判断胎儿心动过缓的预后，并为适当的产科管理提供依据。
