Long QTc Syndrome Type 2 Presenting in a Postpartum Patient on Medroxyprogesterone.
Introduction. Congenital long QT syndrome type 2 (LQTS2) is a rare inherited cardiac abnormality resulting in increased risk of polymorphic ventricular tachycardia (PVT). Case Description. A 21-year-old postpartum female presented with syncopal episode after phone alarm. She was noted to have PVT on telemetry monitoring in the emergency department. EKG revealed QTc of 530. The patient's only medication was medroxyprogesterone. She ultimately received a dual chamber pacemaker with ICD. Discussion. LQTS2 is associated with alarm sounds as a precipitating factor. Postpartum hormonal shifts as well as medroxyprogesterone have significant effect on native QTc duration.
