Management of Bigeminy with Palpitations in Postpartum Women

Initial Assessment and Diagnosis

The European Society of Cardiology recommends that for a postpartum woman with bigeminy and palpitations, the first priority is to determine whether this represents benign ventricular ectopy versus a more serious underlying condition, with most postpartum palpitations being benign and requiring only reassurance and lifestyle modification 1, 2
The American College of Cardiology suggests obtaining a 12-lead ECG in sinus rhythm to look for evidence of structural heart disease, prolonged QT interval, or other electrical abnormalities, and to capture the bigeminy rhythm if possible to characterize the ectopic beats 3
The European Society of Cardiology states that women have longer QT intervals than men, and prolonged QT (corrected QT >0.5 seconds) with bigeminy may indicate early afterdepolarizations requiring different management 4

The European Society of Cardiology guidelines indicate that if structural heart disease is absent and the bigeminy is from ventricular ectopy, this is likely benign, and palpitations in the postpartum period are usually caused by atrial or ventricular extrasystoles and are most often benign 1, 2
The European Society of Cardiology recommends providing reassurance and recommending avoidance of stimulants, including caffeine, smoking, and alcohol, as the Class I recommendation for benign arrhythmias found in the postpartum period 1, 2
The European Society of Cardiology suggests that if symptoms are bothersome despite lifestyle modifications, beta-blocker therapy should be initiated, with metoprolol or propranolol as first-line options 1, 2

The American College of Cardiology recommends performing transthoracic echocardiography to rule out peripartum cardiomyopathy, which can present up to 5 months postpartum but occasionally later, with a diagnostic criterion of LVEF <45% 5
The European Society of Cardiology states that beta-blockers become mandatory rather than optional if structural heart disease or prolonged QT is found, and women with long QT syndrome have substantially increased risk of cardiac events in the postpartum period 1, 2
The American College of Cardiology suggests that if beta-blockers are ineffective, consider sotalol or sodium channel blockers (Class IC agents) in the absence of structural heart disease 1, 2

The European Society of Cardiology recommends that if benign ectopy is confirmed, reassurance, lifestyle modification, and beta-blockers only if symptomatic should be provided 1, 2
The American College of Cardiology suggests that if any concern for structural disease exists, serial echocardiography and cardiology follow-up should be performed 5
The American College of Cardiology recommends assessing for anemia and dehydration, common postpartum causes of palpitations that are easily correctable 6
