Right ventricular outflow tract tachycardia in the parturient.

Parturition is marked by physiological changes that may elicit electrocardiographic anomalies. Sustained right ventricular tachycardia is an uncommon arrhythmia that necessitates cardioversion using physical, pharmaceutical or electrical means. Patients with right ventricular tachycardia must be evaluated for right ventricular dysplasia. Long-term management of right ventricular tachycardia includes beta-adrenergic blockade and/or radio ablation of right ventricle outflow region usually below the pulmonary annuls. This report discusses the case of a 28-year-old previously healthy primigravid who experienced right ventricular outflow tract tachycardia during labor.
