Clinical approach to palpitations in pregnancy

Area of Science:

• Cardiology
• Obstetrics
• Maternal-Fetal Medicine

Background:

• Palpitations are a frequent concern during pregnancy, necessitating thorough evaluation.
• Pregnancy involves significant physiological changes that can increase arrhythmia risk, particularly in women with pre-existing cardiovascular conditions.

Purpose of the Study:

• To review the causes, risks, and management of arrhythmias during pregnancy.
• To emphasize the importance of timely intervention and the safety of anti-arrhythmic medications.

Main Methods:

• Literature review of studies on pregnancy-related arrhythmias.
• Analysis of current guidelines for managing cardiac rhythm disturbances in pregnant patients.

Main Results:

• Arrhythmias in pregnancy can stem from cardiac or non-cardiac origins, with increased risk in those with underlying heart disease.
• While isolated ectopic beats are often benign, some arrhythmias pose life-threatening risks to both mother and fetus.
• Management strategies include electrical cardioversion for unstable patients and medical therapy for stable cases, with expert consultation advised for complex arrhythmias.

Conclusions:

• Early involvement of a specialized pregnancy heart team is crucial for optimal management.
• Reassurance regarding the safety of many anti-arrhythmic medications during pregnancy is important for patient care.
