Idiopathic ventricular tachycardias, which occur in patients without structural heartdisease, are a common entity, representing up to 10% of all ventricular tachycardiasevaluated by cardiac electrophysiology services. Pregnancy can increase the incidenceof various cardiac arrhythmias. Factors that can potentially promote arrhythmias inpregnancy include the effects of hormones, changes in autonomic tone, hemodynamicperturbations, hypokalemia, and underlying heart disease. Ventricular arrhythmias inpregnancy are repetitive monomorphic ventricular premature complexes and coupletsthat frequently originate at the right ventricular outflow tract. New onset symptomaticrepetitive right ventricular outflow tract ventricular tachycardia during pregnancy hasbeen inadequately reported in the literature. We present a case of symptomatic repetitiveright ventricular outflow tract tachycardia that started during pregnancy andcontinued in the postpartum period, requiring curative treatment with electrophysiologystudy and radiofrequency ablation.
