A Novel Presentation: Epsilon Waves in the Electrocardiogram of a Patient with Dravet Syndrome Without Structural Heart Disease

Abstract excerpt

We document for the first time epsilon waves on the electrocardiogram of a patient with Dravet syndrome (DS) who does not exhibit structural cardiac pathology. DS, a severe form of pediatric epilepsy, involves mutations in the SCN1A gene, which disrupt sodium ion flow and increase the risk of sudden unexpected death in epilepsy. The epsilon waves, typically associated with arrhythmogenic right ventricular dysplasi...
