Ventricular Arrhythmias Associated With Long QT Syndrome Type 2 and Anomalous Right Coronary Artery

Patients with congenital long QT syndrome (LQTS) are at increased risk for sudden cardiac death.

We present the case of a young woman with a history of syncopal episodes triggered by emotional stress and menstruation who experienced recurrent ventricular arrhythmias requiring implantable cardioverter-defibrillator shocks. She was diagnosed with LQTS type 2 and found to have an anomalous right coronary artery from the left coronary cusp with malignant features.

This clinical case highlights the complex interplay between LQTS type 2, sex hormonal influences, and an anomalous right coronary artery in a young female patient with recurrent ventricular arrhythmias.
