Does synchronized electrical cardioversion safely terminate idiopathic sustained monomorphic ventricular tachycardia in a pregnant woman?
Synchronized electrical cardioversion can be safely and effectively performed during the second trimester of pregnancy for sustained ventricular tachycardia without compromising fetal hemodynamics.
May support synchronized cardioversion for second-trimester VT; leaves open need for prospective safety data.
The most common cardiac complications detected during pregnancy are an arrhythmia. However, idiopathic continuous monomorphic ventricular tachycardia (VT) during pregnancy is unusual. A 31-year-old pregnant woman presented at 20 weeks of gestation with progressive palpitation and episodes of agitation. An initial 12-lead electrocardiogram (ECG) showed normal sinus rhythm. However, 30 minutes after presenting at the emergency room, she complained of chest pain. A subsequent ECG showed wide complex monomorphic VT. We attempted to administer an antiarrhythmic drug, but the patient refused any medication because of concerns regarding possible adverse effects on the fetus. Therefore, we performed synchronized electrical cardioversion eight times. After the eighth synchronized cardioversion at 200 J, the ECG showed successful restoration of sinus rhythm. The condition of the fetus was monitored via ultrasonography and cardiotocography, and no adverse events were observed. We present the case of a successful synchronized electrical cardioversion performed in a woman at 20 weeks of gestation because of sustained symptomatic VT.

Sung-Min Lee (2018) conducted a case report in Idiopathic sustained monomorphic ventricular tachycardia (n=1). Synchronized electrical cardioversion was evaluated on Restoration of sinus rhythm. Synchronized electrical cardioversion successfully restored normal sinus rhythm in a pregnant woman with sustained monomorphic ventricular tachycardia at 20 weeks of gestation without adverse fetal events.
