Pregnancy is accompanied by a variety of cardiovascular changes in normal women; all of these changes are thought to promote arrhythmogenesis. Atrial fibrillation is unusual during pregnancy and it can represent a benign, self-limited lone atrial fibrillation or can be hemodynamically significant in parturient with or without structural heart disease. Management of atrial fibrillation should be the same as in non-pregnant women, but requires faster intervention, even in patients with a normal heart function, and cautious use of medication to avoid harm to the fetus. We might remember that synchronized electrical cardioversion has been performed safely during all stages of pregnancy.
