New Onset Atrial Fibrillation During Cesarean Section
Abstract Number: 220
Abstract Type: Case Report/Case Series
Dysrrhythmias are infrequent during pregnancy in parturients free of cardiac disease. Most commonly sustained arrhythmias during pregnancy include accessory pathway mediated reentrant supraventricular tachycardias ( SVT) and AV nodal reentrant tachycardias (1, 2) . The new onset of atrial fibrillation in an otherwise healthy parturient is a rare occurrence with only two previous reports noted in the literature. (3,4) We present the case of new onset atrial fibrillation with a rapid ventricular response during cesarean section under spinal anesthesia in a patient free of known cardiac disease.
Physiologic changes associated with routine pregnancy including blood volume expansion, altered autonomic tone, and increased cardiac output can present a perfect storm favorable to dysrhythmia development (5). We expand on the current treatment guidelines for acute episodes of atrial fibrillation (AF) in pregnancy and also discuss the causes and potential complications of AF in parturients and it's associated morbidity.
