TY - JOUR T1 - Long QT syndrome presenting as epileptic seizures in an adult JF - Emergency Medicine Journal JO - Emerg Med J SP - 600 LP - 601 DO - 10.1136/emj.2003.007997 VL - 22 IS - 8 AU - D P J Hunt AU - K Tang Y1 - 2005/08/01 UR - http://emj.bmj.com/content/22/8/600.abstract N2 - A 50 year old woman with a previous diagnosis of epilepsy presented to the emergency department with a generalised seizure. Her admission ECG showed QT prolongation secondary to bradycardia and a subsequent seizure in the department demonstrated that these events were secondary to cerebral hypoperfusion during episodes of torsades de pointes. This case illustrates how long QT syndrome can masquerade convincingly as epilepsy, delaying treatment and exposing the patient to a high risk of sudden cardiac death. Careful ECG analysis is recommended for all patients presenting with seizures. ER -
