Abstract

Advances in human reproductive science are allowing women to get pregnant even at advanced ages. Thus, the incidence of arrhythmic events in pregnancy is rising and represents a significant cause of hospitalization and morbidity for mother and fetus. The most common arrhythmias in this context are atrial fibrillation and supraventricular tachycardia, which acutely can be managed, as usual, with adenosine or cardioversion, and beta blockers in the long-term. For recurrent cases, sodium blockers, such as propafenone, or even fluoroless cardiac ablation can be used. In the context of maternal congenital heart disease, ventricular tachycardia can occur, demanding a specific approach including cardiac defibrillator implant. Unfortunately, the medical evidence in this context is scarce, and most available reviews don't have the objectivity needed to guide daily's practice. This review aims to be a straightforward guide to the approach to tachyarrhythmias in pregnancy.
