Why the study?
It is clinically challenging to distinguish between convulsive syncope and true seizure.
This case highlights the necessity of cardiac investigations in children presenting with convulsive syncope to identify potentially life-threatening underlying cardiac causes such as acute myocarditis.
It is challenging to clinically distinguish between convulsive syncope and true seizure. We describe a 7-year-old girl presenting with generalized tonic seizure caused by acquired complete atrioventricular block related to acute myocarditis. After hospitalization following 6 episodes of new-onset fever with seizure, she had a short episode of abrupt complete atrioventricular block followed by another generalized tonic seizure. The concentrations of cardiac enzymes were elevated, and her echocardiogram showed a decreased left ventricular function. This case underlines the necessity of cardiac investigations in children with convulsive syncope.
