Key result
Electrical cardioversion successfully treats new-onset lone atrial fibrillation during second-trimester pregnancy.
Why the study?
Atrial fibrillation is rare in pregnancy and usually occurs in women with underlying cardiac anomalies, requiring careful evaluation and management.
Case Report (n=1)
Lone atrial fibrillation in pregnancy is rare and can be managed with electrical cardioversion after excluding other etiologies.
Electrical cardioversion may be needed for lone AF in mid-pregnancy; leaves open optimal management without structural heart disease.
In Brief BACKGROUND: Physiologic changes of pregnancy can predispose women to cardiac arrhythmias. Atrial fibrillation is rare in pregnancy and usually occurs in women with underlying cardiac anomalies. CASE: A young woman at 22 weeks of gestation presented with new-onset atrial fibrillation with rapid ventricular response. Thorough evaluation revealed atrial fibrillation with no underlying cause and ultimately required treatment with electrical cardioversion. CONCLUSION: Lone atrial fibrillation in pregnancy requires exclusion of all possible etiologies before diagnosis. Cardioversion is the treatment of choice. Women with persistent atrial fibrillation require anticoagulation and rate control, as well as fetal growth surveillance and antenatal testing. Lone atrial fibrillation in pregnancy is rare and requires prompt diagnosis and treatment to ensure maternal and fetal well-being for the duration of the pregnancy.

DiCarlo-Meacham et al. (2011) conducted a case report in Atrial fibrillation in pregnancy (n=1). Electrical cardioversion was evaluated. Electrical cardioversion was required to treat new-onset lone atrial fibrillation in a young woman at 22 weeks of gestation.
