Evaluation and Management of Pregnancy-Associated Arrhythmias

Show Summary Details


The presentation and management of heart rhythm disorders arising during pregnancy and lactation are similar to those in nonpregnant patients. However, patients who present with a heart rhythm disorder during pregnancy deserve special consideration. Accurate rhythm diagnosis and assessment of symptom severity (especially hemodynamic symptoms) are mandatory. Arrhythmias that result in hemodynamic compromise (usually in patients with structural heart disease) are of major concern—not only because of potential harm to the mother but also because of potential harm to the fetus through reduced placental blood flow. Risks of antiarrhythmic drug therapy during pregnancy include risk to the mother and risk to the fetus. Cardioversion is safe during pregnancy and should be an early option in the management of arrhythmia, especially in the presence of hemodynamic compromise.
