ABSTRACT
The purpose of this case report is to summarize a case of fetal sinus bradycardia resolving spontaneously. In this case report, we summarized a pregnant woman at 22nd gestational week with fetal bradycardia. There was no medical history about fetal bradycardia. Physical examination was normal. Detailed fetal ultrasound examination and fetal echocardiography were also normal. There were no cardiac malformation and fetal hydrops. Fetal bradycardia was diagnosed by M-mode Doppler ultrasound. Heart beat was 78/min. The family was informed about the situation and followed conservatively. After 2 weeks of follow-up, fetal heart rate had returned to its normal pattern. She delivered at 39th gestational week. Postpartum fetal physical and cardiac examinations were normal. The widespread use of fetal echocardiography in the diagnosis of fetal bradycardia among obstetricians would facilitate the determination of the type of fetal bradycardia. (JAREM 2015; 5: 139-41)
