Introduction: Fetal cardiac arrhythmia includes tachyarrhythmias, bradyarrhythmias, and ectopia. The study aimed to examine the findings of fetal cardiac arrhythmia echocardiography.
Method: In a cross-sectional study, the fetal echocardiography was performed by a pediatric cardiac cardiologist for pregnant women with fetal cardiac arrhythmia referred to the pediatric cardiac clinic in Sari (north of Iran) at 2013. Results of echocardiography, mother’s age, number of pregnancy, family history of heart disease were recorded and statistically analyzed.
Results: 60 pregnant women were included in the study. 6 mothers were less than 21 years, 51 mothers between 21 and 35 years and 3 mothers were over 35 years old. Arrhythmias include: premature atrial contractions (PAC) in 45 patients, supraventricular tachycardia (SVT) in 7 patients, bradycardia in 5 patients and flutter in 3 patients. Echocardiography was abnormal in 6 patients including hydrops in 4 patients and Transposition of the great arteries (TGA) in 2 patients. No significant difference was observed between mothers’ age, gestational age and family history of heart disease in those who had normal Echography and patients who had abnormal Echography (P> 0.05). Number of pregnancy has a significant but weak relation with abnormal echography (r: 0.347, P = 0.004). Also, a significant weak relation was observed between arrhythmia and results of echocardiography (r: 0.325, P <0.0003). Conclusion: More parity and presence of arrhythmia such as SVT or bradycardia is more associated with the results of abnormal echocardiography in pregnant women.
