Abstract：Objective To investigate the pregnancy outcomes of pregnant women with arrhythmia without structural heart disease,and to analyze the corr-elation between adverse pregnancy outcomes and arrhythmia types.Methods A total of 283 pregnant women with arrhythmia without structural heart disease admitted to the Department of Obstetrics and Gynecology,Beijing Anzhen Hospital,Capital Medical University from June 2013 to June 2020 were collected.The patients were divided into the adverse pregnancy outcome group and the normal pregnancy outcome group according to the pregnancy outcome.The types of arrhythmia and their correlation with adverse pregnancy outcomes were analyzed.Results Among the 283 pregnant women with arrhythmia without structural heart disease,124(43.8％)had adverse pregnancy outcomes and 159(56.2％)had normal pregnancy outcomes.Among the 124 cases with adverse pregnancy outcomes,9 cases(7.3％)had abortion,22 cases(17.7％)had preterm birth,11 cases(8.9％)had small for gestational age,12 cases(9.7％)had macrosomia,27 cases(21.8％)had fetal distress,2 cases(1.6％)had stillbirth,32 cases(25.8％)had gestational diabetes mellitus,17 cases(13.7％)had gestational hypertension and 23 cases(18.5％)had postpartum hemorrhage.The proportions of premature atrial contraction and right bundle branch block in the adverse pregnancy outcome group were higher than those in the normal pregnancy outcome group(both P＜0.05).Conclusion There is a considerable proportion of the population of pregnant women with arrhythmia without structural heart disease may have adverse pregnancy outcomes such as gestational diabetes mellitus and fetal intrauterine distress.Premature atrial contraction and right bundle branch block are related to the occurrence of adverse pregnancy outcomes,which need to be paid attention to in clinical practice.
