Key result
Multiple cycles of electrical cardioversion failed to restore normal rhythm in a pregnant woman with refractory supraventricular tachycardia, which eventually reverted with anti-arrhythmic medication.
Case Report (n=1)
This case highlights that electrical cardioversion may be ineffective in some cases of refractory SVT with peripartum cardiomyopathy during pregnancy, necessitating prolonged anti-arrhythmic medical management.
May require prolonged antiarrhythmic therapy in refractory peripartum SVT; hypothesis-generating case leaves optimal strategy open.
A case of 28 years primigravida with refractory tachycardia at term is reported. She was refractory to medical cardioversion. Electrical cardioversion was applied before and after the delivery of baby. With several cycles of variable joules of electrical cardioversion, the normal rhythm was not obtained. However, patient’s rhythm reverted to sinus with anti-arrhythmic medication after third week of cesearean delivery.

Rijal et al. (2022) conducted a case report in Paroxysmal supraventricular tachycardia (SVT) refractory to medical cardioversion (n=1). Electrical cardioversion was evaluated on Reversion to normal sinus rhythm. Multiple cycles of electrical cardioversion failed to restore normal rhythm in a pregnant woman with refractory supraventricular tachycardia, which eventually reverted with anti-arrhythmic medication.
