Abstract
Direct current cardioversion is reported as a safe procedure during pregnancy. However, the impact of cardioversion on fetal haemodynamics remains unclear. A 28-year-old woman at 10 2/7 weeks of gestation developed shortness of breath while walking. Under the confirmation of atrial flutter by a 12-lead electro-cardiogram, synchronized shock was proceeded at 17 weeks of gestation and the maternal heart rhythm was converted to sinus rhythm. After 3 months, the baseline of fetal heart rate decreased to 110 beats per minute. Fetal bradycardia was aggravated at term, and caesarean section was performed. Following caesarean section, the infant made a full recovery. Although cardioversion during pregnancy is known to be safe, monitoring of fetal heart rate during maternal cardioversion is advisable considering the possibility of severe fetal bradycardia and loss of variability.
