Long QT syndrome in a patient with complete heart block causing torsades de pointes
Long QT syndrome (LQTS) is an uncommon cardiac disorder of repolarisation leading to prolonged QT interval and T wave abnormalities in the ECG, thus predisposing to Torsades de Pointes (TdP). This condition could either be congenital or acquired. Patients with this clinical syndrome may present with syncope or even sudden cardiac death. We are reporting a case of a 59-year-old female patient who presented to our hospital with a history of dizziness on exertion. Her ECG showed complete heart block and prolonged QTc interval, which precipitated to TdP. Her condition resolved uneventfully after initiation of permanent pacing.
