Paroxysmal tachycardia and cardioversion during pregnancy

Area of Science:

• Cardiology
• Obstetrics
• Maternal-Fetal Medicine

Background:

• Supraventricular tachycardia (SVT) during pregnancy presents a management challenge.
• Pharmacological treatments for refractory SVT may have risks for both mother and fetus.
• Limited data exist on the safety and efficacy of electrical cardioversion in pregnant patients.

Observation:

• A case of pharmacologically refractory SVT during pregnancy was successfully managed with synchronized direct current (DC) cardioversion.
• The procedure was performed without any reported maternal or fetal complications.
• Continuous fetal monitoring was maintained throughout the intervention.

Findings:

• Synchronized DC cardioversion is a safe and effective treatment for refractory SVT in pregnancy.
• The electrical countershock did not result in adverse effects on maternal or fetal well-being.
• Literature review supports the use of this modality for specific arrhythmias in pregnancy.

Implications:

• This case highlights the utility of synchronized DC cardioversion as a therapeutic option for pregnant patients with specific cardiac arrhythmias.
• Healthcare providers should consider electrical cardioversion when pharmacological options fail or are contraindicated.
• Expertise in electrocardioversion techniques and fetal monitoring is crucial for successful outcomes.
