ARRHYTHMIAS: Edited by David Birnie

Purpose of review To discuss the diagnosis and management of maternal arrhythmias occurring during pregnancy.

Recent findings When necessary, current technology allows implantation of arrhythmia management devices and performing catheter ablation procedures with little or no risk from radiation exposure to the fetus.

Summary A variety of cardiac rhythm disturbances can occur during pregnancy, ranging from benign ectopy to life-threatening arrhythmias. In patients with normal hearts and minimally symptomatic arrhythmias, only reassurance is necessary. The quality of the data on managing more serious arrhythmias in pregnancy is somewhat limited, yet with a clear understanding of the maternal hemodynamic changes associated with pregnancy, and the appropriate antiarrhythmic therapies available, almost all cases can be treated successfully. The decision to treat should be based on careful consideration of risk and benefits, yet, when therapy is deemed necessary, it should be administered promptly and with confidence. Drug therapy should be avoided during the first trimester if possible and drugs with the longest record of safety are preferred. The decision to pursue an invasive strategy is complicated by the potential for procedural risks. Yet, the state of modern technology is such that invasive strategies, when justified, can be carried out effectively.
