title: Convulsive syncope in young adults: think of a cardiac cause.
abstract: Convulsive syncope is often misdiagnosed as epilepsy because of its similarity in clinical presentation. We present the case of a patient who had several such episodes before a definitive diagnosis was made. The diagnosis of prolonged sinus arrest was finally made with the valuable assistance of cardiac monitoring during a witnessed episode of convulsive syncope. Appropriate therapy was promptly introduced, i.e. temporary then permanent cardiac pacing. It is possible that any further delay in reaching the correct diagnosis and delivering appropriate treatment might have carried a significant risk of morbidity and mortality. Continuous electrocardiographic monitoring performed at an early stage is therefore crucial in the initial assessment of a young adult presenting with convulsive syncope, as a significant proportion may have a cardiovascular aetiology, particularly arrhythmias, for their syncopal episodes.
