Arrhythmias in pregnancy (RCD code: VII-V)

Cardiovascular diseases in pregnancy are the most common causes of maternal mortality in developed world and an important cause of heart failure, stroke, and arrhythmia. Cardiac disease complicates 0.4–4% of all pregnancies, and arrhythmias are among the most common cardiac complications [1]. In some cases, pregnancy triggers exacerbations of pre-existing arrhythmias, whereas in others it may manifest for the first time [2]. A prior history of arrhythmias or structural heart disease and family history of sudden death are the factors that matter to risk of tachyarrhythmias during pregnancy [3]. Due to extraordinary ethical considerations in pregnant women, there are only a few randomized studies and little data on efficacy or safety of antiarrhythmic drugs applied during pregnancy [4]. Therefore, much of clinical care is guided by general knowledge about hemodynamic changes in pregnant women, universal principles of treatment of arrhythmias and finally by gained experience in that area. Multi-disciplinary approach remains the overriding principle in management of pregnant woman with arrhythmias, including collaboration with gynecological and obstetric center.
