Abstract

Biz yapısal olarak normal kalp ve 21. gebelik haftasında (w.g.) fetal kalp hızı 74 bpm olan bir fetüste geçici ikinci derece 2:1 iletim AV bloğu olgusunu sunuyoruz. Annenin tıbbi öyküsünde özellik yoktu ve otoantikor taraması negatifti. Sonraki takip, AV bloğunun 25 w.g’de tam çözünürlüğünü belgeledi. Fetal kalp hızı ve AV iletimi doğuma kadar normal kaldı. Doğum sonrası EKG normal sinüs ritmini ve QTc aralıklarının süresini gösterdi. Takip sonrasında bu gözlemler normal kaldı. Nadir de olsa ikinci derece AV blok, fetal bradikardinin altında yatan nedenlerden biri olabilir.

Abstract

We present a case of a transient second-degree 2:1 conduction atrioventricular (AV) block in a fetus with a structurally normal heart and fetal heart rate of 74 bpm at 21 weeks of gestation (WG). The maternal medical history was unremarkable and the autoantibody screening was negative. The subsequent follow-up documented complete resolution of the AV block at 25 WG. The fetal heart rate and AV conduction remained normal until delivery. The postnatal electrocardiogram (ECG) demonstrated normal sinus rhythm and duration of corrected QT (QTc)-intervals. These observations remained normal upon follow-up. Although uncommon, second-degree AV block can be one of the underlying causes of fetal bradycardia.
